Sailing in Different Conditions
You really need to experience sailing a Finn in order to fully understand
what it is all about and as many have found out in the past, once bitten
by the Finn sailing bug it is hard to give it up. Special techniques need
to be learnt, understood and then mastered to make sure that at all times
in a race you are in charge of the boat and have the ability to put the
boat where you want it to be. Most techniques require a combination of
coordination, finesse and sheer brute strength. It has to be said that
to handle the boat well in a strong breeze you have to be 14 stone plus.
Many people of a lesser weight can and do sail the boat competently in
all conditions, but the extra weight undeniably provides a significant
advantage on the windier days.
When analysing a certain aspect of boat handling or control, it is usually
best to break down each action into its constituent parts so as to gain
a better understanding of what needs to be achieved. That is what has hopefully
been accomplished on the following pages. In this chapter there is a basic
subdivision into upwind and downwind sailing, followed by a further breakdown
into areas of boat manoeuvring and sail control while considering specific
aspects such as beating, tacking, gybing, surfing etc. The idea is to present
a general picture of what, how and why a Finn is sailed the way it is.

First Things First
When all is said and done and you hit the straps out of the start line,
the best gear in the world is not going to get you to the windward mark
first if you don’t sail the beat correctly. Get the first few shifts wrong
and you might as well be sailing the slowest boat in the fleet for all
the difference it will make. Fail to set the sail correctly for the conditions
of the day and you may as well have used a blown out old relic rather that
the state of the art. Good gear is important, yes, but it MUST be used
properly to get the best out of it.
Wind
Consider what the wind is doing. There is only one thing that is definite
about the wind - that is that it is never constant in either speed or direction
for any length of time. It is therefore essential to use your compass and
intelligently consider what the wind is doing and what it is likely to
do during the race. The importance of this cannot be overestimated. A slow
boat can get to the windward mark before a faster boat if the slower boat
takes a better route. Everything that follows here is useless unless you
get this bit right!
Setting the Sail
Most sail setting ability comes from experience within the class over
a wide variety of conditions, learning the ‘look’ of a fast sail and being
able to repeat fast shape settings. As a basic guide though you should
be considering the following when setting up a sail on a mast:
• fullness for the conditions of the day
• mainsheet / kicker to give correct leech tension.
• don’t oversheet - if underpowered or stalled, ease sheet and build-up
speed again
• adjust traveller and mainsheet for pointing or for power
Basics
What the above has tried to spell out is that you must get the basics
right before anything else. Work on the rest of it as well perhaps, but
don’t expect large gains until you have mastered the basic sailing of the
boat. A new sail will improve your speed, yes, but not as much as using
the sail correctly, getting a good start and tacking on the first few shifts
correctly.
Summary
Kicker - leech tension offwind (i.e. twist)
Outhaul - lower sail fullness and angle leech
Inhaul - angle of entry at luff and angle of lower leech
Cunningham - draft position in sail and upper leech fullness
Mainsheet - leech tension upwind and angle of attack offwind
Traveller - angle of attack upwind

Basic Finn Sailing to
Windward
Although at first sight the Finn rig may seem to be a relatively simple
piece of gear compared with other boats of a similar size, almost as many
problems can be encountered in tuning it as in two-sailed boats. The first
difference that a novice Finn sailor will notice is that the boom is sheeted
at an angle to the centreline and never on the centreline. Because the
Finn does not have a foresail, airflow is not specifically directed along
the back of the mainsail. The air therefore breaks away earlier than would
be the case with a foresail present. To move this break point further aft
the maximum draft is cut into the sail at about half the chord length.
This produces a resultant force which is angled further aft than would
normally be the case. To overcome this, the traveller is slipped to leeward
to increase the angle of the boom to the centreline and hence shift this
resultant force angle to point further forwards so that the driving force
is moving the boat forwards rather than sideways. It will be seen later
that the windier the conditions experienced the further the boom is let
out. It should never be sheeted further in than the inner sidedeck and
the end can sometimes be a matter of several feet away from the gunwale
in a strong breeze.
Before we look into sailing the boat, here is a description of the controls
available on the Finn.
Kicking Strap
The kicking strap, usually a powerful lever system bolted onto the
boom with a number of purchases attached to it, controls the leech tension
and hence is basically a power control. Upwind it is generally ignored,
leech tension being gained through the mainsheet. Offwind, the kicker is
increasingly tensioned as the wind picks up to keep the leech tight and
contain the power.
Cunningham
The Cunningham controls the fore and aft position of the point of maximum
draft in the sail. As the wind increases the draft will be pushed
further aft in the sail, making the boat hard to control. (The resultant
force points aft or sideways again.) Tensioning the Cunningham will bring
the draft and the force angle forward again. It also has the effect of
opening up the top half of the leech, essential in very windy conditions
to de-power the sail when the helmsman is overpowered.
Outhaul
The outhaul is used to control the fullness in the bottom of the sail
and the angle of the leech. When the outhaul is tensioned, the foot is
flattened and the leech is opened. In light airs the outhaul is eased,
bringing the clew nearer the mast. This puts fullness into the bottom of
the sail and makes the leech stand up - i.e. point more to windward which
causes weather helm and gives the rudder more 'feel'.
Inhaul
The inhaul is used in conjunction with the outhaul to flatten the bottom
of the sail. It also opens up the lower leech and removes fullness from
the luff when it is tensioned. Tensioning the inhaul will open the lower
batten and lessen weather helm. Releasing the inhaul will close the lower
batten and create weather helm - letting you point higher.
Mainsheet
Often overlooked as a sail control, the mainsheet has more effect on
sail shape than all the others put together. Mainsheet tension is critical
both to pointing ability and to power (boatspeed). When the mainsheet is
pulled in, the sail is progressively flattened. This action causes the
leech to hook, so some inhaul/outhaul tension is required to open it up
again. A flatter sail will help you to point higher although some power
will be lost. Easing the sheet will have the reverse effect in that you
will gain power but lose some of your pointing ability. In all instances
a compromise is necessary when deciding whether to go for power or pointing
- you cannot always have both. Care should be taken when setting the sheet
so that it is not undersheeted (giving you no power and no pointing) or
that it is oversheeted (making you point very high but travelling very
slowly) and it should be appreciated that the mainsheet should always be
used in conjunction with the other sail controls to obtain the best shape
for the conditions of the day. How hard you tension the mainsheet (and
hence the sail) will always affect what you need to do with the other controls
to set the sail correctly.
Note that if you are using an old sail that has seen its best, you will
have to do more to it to flatten it to the same degree as a newer sail.
The draft will probably be further aft in the sail, requiring more cunningham
tension to move it forward and generally more tension to take the fullness
out.
Rudder Feel
The feel of the rudder is an important aspect of Finn sailing. Weather
helm is necessary to make the boat point in light airs and give the rudder
enough feeling. This can be induced by slackening the inhaul so that the
tack of the sail moves away from the mast. To go for more speed in a breeze
the inhaul is tightened to open up the bottom batten and make the boat
easier to steer. Easing the outhaul a touch also has the effect of inducing
more weather helm and helping pointing ability, but don't ease it too much.
When sailing the Finn for the first time it is important to get the
basics right before attempting fine tuning and sail control. Make sure
that you can hike comfortably so that you can look up and see where you
are going with ease. Whoever can hike the hardest for longer has an immediate
advantage. Alter sidedeck pads and add toestrap pads where necessary. Make
sure the mainsheet flows freely and has a ratchet block on the floor. Also
check that the boom can be brought down to touch the deck, as this is where
it will be when sailing to windward in any sort of breeze.
Boom Position
The first thing to get right when sailing a Finn to windward is where
to set the boom - its height above the deck and its angle to the centreline.
The boom end will start off in light winds roughly in the middle of the
sidedeck and about a foot to a foot and a half above it. As the wind increases
the mainsheet is tensioned to bring the boom down to meet the deck. The
traveller is then eased so that the boom end is eventually carried outboard.
By tensioning the mainsheet and bringing the boom lower, you are bending
the mast and flattening the sail and hence allowing the boat to point higher.
How much the mainsheet is tensioned depends on the wind strength and the
stiffness of the mast. A stiff mast will require a flat cut sail and a
soft mast will require a full cut sail. As the mainsheet is tensioned the
mast is bent forwards between the gooseneck and the mast tip, taking fullness
out of the sail as the mid section of the mast is forced forward. A softer
mast will curve forward more than a stiff one and hence will take more
sail with it and make the sail flatter. Your aim should be to keep all
of the luff tell-tales flowing all of the time. If you over-sheet, the
leech will become excessively hooked and the boat will feel sluggish.

Light Airs
In light airs, you should be perched on the sidedeck with slight mainsheet
tension and all controls eased to provide a powerful sail. Care should
be taken not to ease the outhaul to much as this is likely to cause the
leech to hook and slow the boat. As the wind increases and you have to
start to hike out to keep the boat level, the boom should be gradually
brought down to the sidedeck. This bends the mast more and hence produces
a flatter sail. At the same time as flattening the sail by tensioning the
mainsheet, it should also be flattened by gradually tensioning the outhaul
and also the inhaul and Cunningham when it is very windy. As you hike harder
and flatten the sail it may be necessary to slip the traveller to keep
the boat upright. The boat should only be sailed with a slight heel in
very light winds so that the heeling can be used to develop the natural
shape of the sail when the wind is not strong enough to do it.
Wind and Waves
If you are sailing on the sea and the wind picks up, the chances are
that waves will start to develop. If this happens it may be necessary to
slip the traveller earlier than you would do on flat water in order to
control the boat. In largish waves much steering action will then be needed
to keep the boat moving. Slamming into a wave will stop the Finn in its
tracks so it is essential to steer round each wave, a strength sapping
practice when it is windy. As you sail up the face of the wave, the apparent
wind will free so you must head up to cut through the crest at a more acute
angle. Once over the top the apparent wind will move forward and so you
must bear away down the wave, doing so in enough time so that the bow does
not slam into the trough but goes smoothly down the wave, keeping the speed
up. Therefore the process should be one of heading up to meet the crest
of the next wave and then bearing away sharply down the face of it to keep
the boat moving.
Steering
In rough conditions, constant and often vigorous and rapid steering
is required to keep the Finn moving. Cessation of proper steering technique
will result in the slowing of the boat due to hitting the waves and increased
heeling. Conversely in flat water rudder use will only act as a brake and
it should be used as little as possible, the boat being controlled by its
angle of heel and mainsheet tension.
There are two ways of sailing the Finn to windward. It can either be
sailed for power or for pointing. Generally you have to go for power before
pointing in order to build up speed and only then begin to head the bow
slightly up into the wind to start gaining height. In strong winds, light
helms have little option but to go for pointing because body weight is
vital for power sailing. Usually all helms will use a combination of each
technique during a race as the situation they are in dictates. Perhaps
a bit of power to get some speed off the start line and some pointing later
on in the race to lay a mark or escape from a leeward boat or stuff a windward
boat.
The table above basically shows what should be where in different conditions.
Don’t take it all literally though. It’s just a guide. With a different
sail and a slightly different chop, some of these settings may vary considerably.
Just use them as a pointer and most importantly, understand why!

Hiking and Steering
Sometime ago a Finn turned up at a National Championship and went around
the course, after a fashion, heeled at an angle of somewhere between 35
to 50 degrees, yet the helm was working really hard. So hard in fact that
the back of the helmsman's legs were against the side of the hull when
going upwind! Either this guy was super fit, a masochist or had forgotten
to shorten his toestraps! Something was a little wrong. A comment was passed
at the Finn Dinner, 'Sit up and look where you are going.' What was this
new concept?
Well, first of all become very self critical. Never accept mediocrity.
Either try to do it well or take a complete rest from sailing! Secondly,
find a comfortable hiking position from which you can 'work'. When a Finnster
is steering well through a classic sea breeze chop, the amount of energy
expended is considerable. He needs to be able to breathe well, to look
up at the sail, the compass, the waves, the gusts and the other boats.
All these activities need thinking time. This will not happen if the poor
old chap is incapacitated with pain and excess sea water from the last
wave. We all know - we have all been there!
It goes without saying that the boat should have wide padded toestraps,
pussy pads with or without camping foam underneath to suit the helm and
the helm could perhaps also wear a decent set of hiking shorts. The toestraps
should be adjustable in order to change your body position in relation
to the wind strength, waves and fatigue.
Hiking
Hiking positions change from the bent leg position through to the classic
drooped 'W' position, then to the extended power position for special circumstances,
depending on: the wind strength, ability to steer effectively, weight and
personal strength. Note that the most frequent problem is the misconception
of beginners of the need to hike like a Soling crew: not only is this difficult
without a harness, but there is a tendency to drag your body though the
water, and most importantly it is difficult to breathe or to see properly.
Fast Cruise or Flat Out
Bearing in mind that a Finn race might last 2 hours or more, plus time
sailing out and back, the helm needs to evolve a 'fast cruise' hiking position.
Therefore Finn sailing at the high standard that the vast majority of us
do in fact reach, is like the 1500 metres; you need to be able to turn
it on when it matters and to rest at times in readiness for the next interesting
bit.
When in a race, should a Finnster put in a bit of extra effort and sail
flat out?
-
at the start of a race to break out of the melee to find clean air
-
when the wind gusts up and before the helm can de-power the rig to compensate
-
after each tack to get the boat back up to full speed and everything working
well
-
getting a good windward mark rounding
-
boat to boat problems
-
pumping down the reach and run
-
on the finish line, either to impress that pretty young lady on the committee
boat or to get a better race result.
Apart from the above situations it is better to adopt the 'fast
cruise' mode. 'Ah yes,' retorts the beginner, 'but my boat is still going
along on its ear making horrible sucking noises!' First things first -
you are now in a hiking position where you can breathe, look, listen, feel
and make good decisions on what to do....that’s it - engage brain now -
clunk!
Steering Style
Steering is that very important sail control that virtually everybody
forgets to stress in sailing articles. You need to really steer a
Finn in comparison to other dinghies. As far as the Finn is concerned,
the rudder has more effect on how soon the windward mark is reached than
all the other sail controls put together. The very basics first. In all
hiking positions, try keeping the upper tiller arm down the side of the
chest, the elbow then allows the forearm to come across to roughly the
middle of the stomach and parallel to the tiller. Thus the tiller extension
is held with the palm of the hand on top of the extension. The advantages
of this style may not be apparent at once, but in the end the helm will
get more feel from the rudder such as:- over-steering, weather helm, helm
suddenly gone light, run aground! Those small rudder movements that give
better control are also easy to make continuously.
That is the arm bit, but how the tiller extension is held is also important.
The thumb extends up to the free end of the extension with the fingers
folding round the extension naturally. Simple perhaps, but in light weather
there is no need to clench the extension until the whites of the knuckles
show. Varying the grip slightly with the wind and wave conditions will
all help to give better control and response; also essential for that all
important feedback of information that you get from the boat. In heavy
air grip the extension with the hand only just sufficiently hard enough
to steer the boat in an easy fluid but positive motion. As the wind lightens
not all the hand needs to be used, with the extension being held by just
the thumb and finger tips. But beware of holding it too loosely and dropping
it when the rudder gives an unexpected pull.
Sheeting In
All steering movement comes from lower arm movement below the elbow,
because far better control is gained in comparison to moving the whole
arm from the shoulder. Holding the tiller in this way, the mainsheet can
be pulled in quickly and smoothly using the steering hand. The free arm
grabs the mainsheet by the floor block and pulls the sheet up and across
the helmsman’s chest to the hand on the tiller extension. The last three
fingers on the extension hand hold the sheet stationary as the sheet arm
goes back down to the floor block for another armful of mainsheet. At the
leeward mark a far longer pull is possible, by standing up, sheeting in
from by the floor block to above the helmsman's head, the tiller extension
hand catching the mainsheet at waist level. In such cases of leeward mark
rounding, the boat needs to be sailed round even the tightest of mark roundings.
The Finnster should be positively steering and putting his boat where he
wants it to be in relation to the mark and the other boats. At times like
pre-race manoeuvres, when things get hectic, these refinements must be
second nature as the Finnster must make the time to look round at other
boats, wind gust patterns on the water and awkward waves, in order to get
in there and really race.
Upwind Priorities
sail trim = boat speed
positive and firm steering through waves and gusts

sail instinctively - watch the race, not the boat
|
Reading the Water
So, armed with the fundamentals of an effective hiking position, good
steering position and smooth steering techniques, the young Finnster has
the basics with which to work the boat through the waves and the gusts.
So some thoughts now on how to use these tools in different conditions.
The biggest mistake is not looking upwind and 'reading the water'. Quite
surprisingly air is quite invisible and compasses on a boat only tell the
direction of the wind at that immediate moment, but never forecast what
it is going to do, or at what strength. What to look for? If behind several
boats, look at the mess the guy in front is making of dealing with the
gusts, or how well he responds to them! Watch to see when his rig heels
over as the wind gusts and lulls and work out how long it will take for
that wind to reach you. What should be done?
Read the water. Scan the water upwind over an arc of 90 degrees to windward
and ahead of the boat, virtually all of the time, in the order of 50 to
500 meters ahead. A puff of wind shows up as a darker patch of water. Look
hard and look for the different types of ripples - small to large ones.
Is it a big patch stretching way back upwind or is it just a localised
gust? Usually the darker the patch the stronger the gust; does this mean
there will be five minutes of stronger wind requiring a touch of Cunningham
or dropping the boom down an inch or so? This is the normal panic measure
written up in all the sailing books, but consider leaving all the control
lines alone for once and think - rudder!
Rudder Usage
Leave all those sheets cleated and put that big powerful rudder to
work. Try to keep the boat dead level using the rudder to feather up momentarily
and then getting back on the wind immediately. The sail should never physically
flap or flutter in the luff at all, in fact the tell-tales should be flowing
almost all of the time. The rudder at times is used as if you were sculling,
but moving the end of the tiller by only 10 inches at the most, the rapidity
of movement increasing with wind strength. Obviously nothing is ever constant,
so be prepared to deal with the awkward big wave, by superimposing the
luff or deviation round the wave with the steering to keep the rig dead
upright. Sheer weight and height is not going to keep the boat upright
alone, so keep in the comfortable 'fast cruise' position. It will become
very obvious why, as those old arm and shoulder muscles will ache after
a time so you will need space to breathe. If you overdo the feathering,
which is an easy mistake, the boat slows, gets bashed around by the waves,
heels over and slips off sideways. For the purposes of training, drop the
traveller right off and try to keep the luff full as before. Out on the
race course this is suicidal, so put a tell-tale half way up the luff and
at mid-chord. When the boat is being stuffed excessively, look at the special
tell-tale and try to keep it flowing all of the time.
Look Around
Obviously before the start of a big race, when the adrenalin quite
naturally causes ‘nerves’, go out onto the race area early. Once out there,
get the boat tidy and into race/combat state, and then go off upwind towards
the windward mark. After five minutes of sailing upwind away from the other
boats, having thrown a few tacks to loosen up - stop. (If your brain is
not engaged, do so now.) With the boat pulling gently upwind on a half
sheeted sail, look around and to the windward mark.
-
What are the waves like, perhaps a little bigger, but how close together
are they?
-
Looking at the water in more detail can you see the wind gusts on
the water?
-
Can you find the windward mark easily and also the wing mark?
-
Is there a land feature to guide your line of sight to the windward mark
quickly?
Thinking back on all the practice that you have been putting in,
what sort of sail shape do you want, how much camber do you reckon you
need? Now readjust the sail if need be. Having done all this make sure
that you do not miss the start though. Sail upwind as though racing and
really use that rudder to keep the weather side of the foredeck level with
the horizon. If you start 'stuffing it', drop the traveller and foot for
a few moments. Then perhaps gradually pull the boom end towards the gunwhale
until you have found the right position. Just check this for both sides,
for equal time. If you have a compass, obviously note a few readings down,
ready for the race.
The above points form the basics of windward boatspeed. Windshifts and
current are far better explained by professional writers, but these are
absolutely essential to get right so you do not have to sail an extra half
mile. The Finn rig is a elegant piece of kit but you must understand what
the sail controls do and how to apply them - so engage brain. There is
no getting away from the fact the the Finn needs more physical strength
than other toy boats, but hiking badly will not help. Finn sailing is a
subtle blend of physical prowess and intense understanding of the technical
elements of yachtsmanship. Anybody who knocks this class is probably deficient
in either one of these areas. This deficit may be overcome, over several
years of sailing but only if one sits and looks where one is going. There
is a lot to see and learn out there.
The Fundamentals of Winning:
Simple Compass Work
At the 1991 European's prize giving, Charles Currey pointed out that
the Championship winner was lighter than the second placed man. Big is
not necessarily best, but a brain is certainly of use; the use of eyes
and careful analysis of the total picture at a rapid rate is essential
for anyone wanting to win.
The next most important piece of kit after a good sail is the compass.
As with the sail, the compass needs to be used intelligently or it is just
a waste of space. Intelligent use of it can provide you with a route up
the beat that can be 20 per cent shorter than many other boats may be sailing.
This sort of advantage is too big to just throw away through lack of straight
thinking, so get used to using the compass all the time. It can be used
in any number of circumstances:
-
determining bias on start line
-
determining position on start line
-
finding marks of the course
-
tracking shifts in wind
-
determining which tack to start the beat
-
determining which gybe to start the run
Positioning of Compass in Boat
Older boats often had twin compasses on each sidedeck, but by far the
most popular position today is in front of the centreboard case on the
strut that joins the centreboard case and the foredeck. Have it as big
as possible so it is easy to read, but make sure that when the centreboard
is raised it does not hit the compass.
Use on Start Line
Take a bearing of the line and of the wind. Work out the difference
to decide which end of the line makes a smaller angle to the wind and start
at that end. With a bearing of the pin your approach can be more accurate.
Just sight the pin and when the bearing corresponds to the noted one you
are on the line. If the bearing to the pin is greater than the line bearing
then you are behind the line.
Tracking the Wind
One of the most important pre-race actions is to periodically check
the direction of the wind or the course the boat is making on either tack.
Then, for any given wind direction you will know if it is currently veered
from the norm, backed from the norm or near the norm - and then be able
take the appropriate action. Sail for a while a either tack and note down
a range of compass readings. These will not be wind bearings but boat headings
and you will have a different set for either tack. If the bearings increase
the wind will have veered, if the bearings decrease the wind will have
backed.
If the wind is continually shifting in one direction then this will
be picked up and can be acted upon. If you don't look you won't find. Geographic
variations are more difficult to detect - you have to sail a good part
of the course to find these. If the race area is downwind from the launching
area then check the wind when you arrive at the windward mark and periodically
down to the starting area. This will save having to sail a beat before
the race.
If the wind swings round to the left - backing - and the boat is on
starboard tack you would be headed, the compass reading would decrease.
Therefore to avoid sailing the longer course tack onto the now favoured
port tack. If the wind were to swing back to the right - veering - the
port tack reading would increase and it is time to tack back onto starboard.
The simple reason why it pays to be on the correct tack is that a boat
sailing on the wrong side of a five degree shift doing five knots for a
minute against a competitor on the correct opposite tack will be 20 yards
or five boatlengths behind the competitor. Use the adage - Plus Port (tack);
Subtract Starboard (tack). Scribble down all the port tack readings and
all the starboard tack readings as you sail the trial beats.
The above scribbling produces a critical piece of information - the
average wind direction for the forthcoming race and the key wind direction
against which wind shifts are compared. Taking the average wind direction
reading into account it is not always necessary to tack on a small header
if the compass reading is showing the current tack is favoured. If for
instance the compass values have been between 70 degrees and 90 degrees,
the average wind direction must be 80 degrees. If the boat is sailing on
starboard on 90 degrees and the compass reading falls, but to just over
80 degrees, there is no need to tack. As soon as it goes below 80 degrees,
then it’s time to put in a tack and repeat the process on the new tack.
Easy really.
Example: (assume port hand triangle / sausage / beat)
This may be an oversimplified version of events in a typical race but
it does highlight some important points of compass use.
-
wind readings are: mean = 0 degrees (45 degrees on port; 315 degrees on
starboard), veer = 10 degrees (55 degrees on port; 325 degrees on starboard),
back = 350 degrees (35 degrees on port; 305 degrees on starboard)
-
line readings are 260 degrees and 80 degrees - starboard end bias of 10
degrees (mean wind direction)
-
sail triangle
-
in veer ( port tack reading > 45 degrees) tack onto starboard
-
in back ( starboard tack reading < 315 degrees) tack onto port
-
round leeward mark and head up - wind = 5 degrees (50 degrees on port),
therefore tack onto starboard
-
approaching windward mark - wind = 355 degrees (310 degrees on starboard),
therefore start run on starboard
-
later on run - wind = 5 degrees, gybe onto port
-
on the run gybe on the lifts
-
round last mark and head up, wind = 350 degrees (40 degrees on port), stay
on port tack
-
play shifts up to finish
A compass merely records what the wind has just done, it does not tell
what is going to happen. The reader is strongly advised to read 'Wind Strategy'
by David Houghton wherein more useful titbits can be gleaned to make the
compass as devastating a weapon as you will ever find.
Tacking The Finn
When sailing competitively there are certain areas of sailing that can
be improved upon more easily than others. For example - boat handling skills
are trainable, easily learnable skills where an immediate improvement in
their execution can be seen through the correct technique. The more abstract
skills of feel, concentration, mental preparedness are much more difficult
to practice. Tacking is one of the areas that can be worked on a great
deal during race training and here is described a typical analysis of tacking
a Finn
To start with we will assume that the sailor is in the hiking position
on a close hauled course. It is the combination of hiking position, tiller
extension, low boom and the predominantly high weight of a Finn that allows
a unique technique to be employed during a good tack.
First of all the boat should be set up with the tiller end bent down.
This allows full movement of the tiller when the extension is pushed away
from you, preventing the tiller simply banging on the boom. Tack the Finn
as follows:
-
you are hiked out, boom cleated on the deck ready to tack in response to
the windshift
-
uncleat the mainsheet and smoothly push the tiller across to the other
side of the boat
-
simultaneously sit in onto the side deck, unhooking your feet
-
lean down with your mainsheet holding front hand moving down to the floor
block (this movement allows the boom to lift and the tiller extension is
continued to be pushed across to the leeward side of the boat)
-
as the boat goes through the wind, begin to move across towards the new
side of the boat, moving your back foot first
-
the tiller extension is kept firmly in the back hand and if the wind is
lighter you should attempt to induce a small amount of roll in order to
increase speed out of the tack
-
immediately you have moved underneath the boom, centralise the tiller and
simultaneously stand up while keeping the same grip on the mainsheet so
that the boom will be pulled down hard onto the deck
-
this action allows the boat to shoot into the wind momentarily allowing
a small amount of height to be gained
-
sit on the new side deck, lean your arm across your body and place the
mainsheet in the cleat.
-
control the amount of heel by pulling the tiller slightly and bear away
to your new close hauled course.
This technique achieves two things:
1 the action of shooting the wind gains height through the tack
2 the action of standing up allows the boom to be pulled down to the
deck using the leg muscles only. This is better than allowing the sail
to fill on new close hauled course allowing the boat to heel and then pulling
it down whilst hiking by using the arm muscles alone which will then fatigue
much faster!
In lighter winds a slightly different technique is employed because
the boom will be higher up and not down on the deck. In this case the helm
is usually perched on the inside edge of the side deck. When the tiller
is pushed away and the boat rounds up into the wind the mainsheet tension
should be increased slightly. As the boom comes into the centreline the
helm ducks down and at this point the mainsheet will be eased by the action
of ducking down. The helmsman goes underneath the boom and up onto the
new side sheeting out the mainsheet as required in order to produce the
correct mainsheet tension for the new tack. The important point to note
here is that sailors who weigh 14 or 15 stone are able with this technique
to induce a good deal more roll in the tack than those people who weigh
13 stone.
You will know when you have executed a good tack because the boat will
shoot out of the tack smoothly and at speed. Break down the tack into smaller
components and 'visualise' each action during the tack - where you and
the boat should be at any particular point. Then practice each part until
the tack is fluent and smooth. The major element is to maintain boat speed
through the tack, especially important in waves when a bad tack can stop
the boat dead in its tracks.
Steering by Balance
The rudder is just about the most inefficient way of steering the boat
that there is. Instead try using the sail, the centreboard and a bit of
heeling to accomplish it. Steering will then be much more fluent with hardly
any drag from the rudder.
To help the boat head up
-
heel to leeward
-
sheet in
-
drop centreboard
To help the boat bear away
-
heel to windward
-
sheet out
-
raise centreboard
These techniques work because you are using the forces on the hull
and sail to assist in the steering. Normally these forces are balanced
because you want to go in a straight line. As soon as you alter their positions
relative to each other they start to work to against each other to turn
the boat one way or the other.
Slow Speed Boat Handling
There are times during a race when it is essential to be able to handle
your boat at slow speed. For example on a packed start line when you do
not have the luxury of being able to do as you please. If you want to make
a good start then you have to be in there with the rest of them putting
the boat where you want it to be when you want it to be there! This is
not something that comes easily, but only with experience and practice.
There are four basic manoeuvres that you need to master. These are: stopping,
starting, moving to leeward and moving to windward.
Stopping
If you find yourself being edged forward toward the start line too
early then you need to be able to stop the boat and perhaps sail it backwards
for a bit. The best way to stop in a hurry is to reach forward and push
the boom out to windward so that it fills on the wrong side. Don’t push
for too long or you will find the boat moving backwards - the last thing
you want to happen on a packed start line. Just stop the boat and then
make it stay head-to-wind by using the rudder and mainsheet. Be careful
not to get stuck in irons because then you really will start to move aft
and may have trouble slowing down.
Starting
An ability to get your boat moving quickly often separates the good
sailors from the average. It means that you can:
-
get off the start line more quickly
-
come out of a tack or a gybe quickly
-
round marks better
If the helm that does each of these well gains 1 boatlength over
the helm that does each badly, during a race that can mount up to a large
gain (assume 5 mark roundings, 10 tacks per beat, 3 gybes = 38 boatlengths
- 171m!)
It is therefore necessary to be able to accelerate the boat to maximum
speed in the minimum time. Assume you are stationary and sitting almost
head-to-wind. Heel the boat to leeward, bear away from the wind and then
squeeze the boat upright whilst sheeting in and heading up to the wind.
This action should squirt the boat forwards. It is the same procedure as
the latter half of a roll tack.
If you are stationary or are stuck head to wind or just want to turn
the boat and get going quickly grab the last purchase of the mainsheet
direct from the boom and pull it to windward. The bow should rapidly swing
away from the wind. Drop the mainsheet, sheet in and go.
Moving to Leeward
You might need to move the boat to leeward if for example you are just
over the start line and need to move back slightly but have not got time
to sail round and retake up your position. If sitting with your sail flapping
does not help, pull your board up into the case. You will now drift rapidly
sideways. Keep hold of the uphaul to release it the moment you are in position
or you could end up going too far. Likewise you could use this method to
come in late at the windward end of the starting line by drifting in sideways
until level with the line and then dropping the board.
Moving to Windward
It is not really possible to move the boat to windward legally. It
can only be done by putting in two quick tacks. What you really have to
do is to maintain position on the start line better that the next boat
to leeward. Push the boat into the wind, then gain control. The bow will
gradually swing away from the wind again so push it back into the wind
again. The trick here is to be able to do it without moving the boat forwards.

with lots of practice in still water

Basic Offwind Finn Sailing
Sailing a Finn offwind in a strong breeze can be one of the most rewarding
experiences around. The exhilaration of the acceleration and power, slicing
through the water with spray flying over your head is something that has
to be experienced first hand in order to be fully appreciated. While most
races are won and lost on the upwind legs of the course, it has to be said
that distance lost (or gained) offwind is much harder to regain upwind.
Downwind speed is mainly dependent on good concentration and balance when
sailing in light airs but is much more dependent on strength, technique
and coordination in strong winds.
Balance and Steering
When sailing the Finn upwind in a breeze, vigorous steering is often
needed to gain the best performance. When sailing offwind, the opposite
is usually the case, the rudder acting as a brake every time it is used.
You should aim to use the rudder as little as possible, because every time
you use it you will be slowing the boat down. Instead, steer by balancing
the boat and by continuous trimming of the mainsheet. When there
is any breeze the boat should be kept level, but when there is very little
it should be heeled to windward on a run and to leeward on a reach. However
beware of heeling to leeward in a breeze as any gust coming through could
catch you unaware and tip you in. Heel the boat to aid steering.The boat
can be made to turn, gybe and tack faster just by using a combination of
boat heel and sheeting. Obviously the rudder is going to have to be used
at some point but when you do use it, use it gently and smoothly so as
to maintain boat speed. One final point here, make sure that your rudder
system has no play in it at all. All joints should be tight fitting so
that the boat responds immediately the helm is moved and not a few seconds
afterwards. Also make sure that your mainsheet is long enough to let the
boom out to 100 degrees from the centreline.
Sheeting
As soon as you are sailing free such that the boom is a few feet out
from the gunwhale the sail can be sheeted directly from the boom using
the last purchase of the mainsheet. This gives a much better feel on the
sail. You can feel the puffs and lulls as they arrive and can respond to
a change in direction much more quickly. As the wind increases you may
have difficulty holding onto the single sheet. There are various other
ways that the sail can be sheeted other than through the floor block with
three purchases or directly from the boom.
1 Cleat the sheet in the sidedeck cleat or let the sheet run through
the bottom block until it reaches the stopper knot (the latter is not practical
on a close reach). Pick up the purchase from the traveller to the block
on the boom and then sheet from the block on the boom.
2 Take the sheet from the other side of the floor block and then sheet
straight from the block on the boom.
When sailing in medium to strong winds, sheeting the boom through less
purchases gives an advantage when the sail is pumped because the pump will
be sharper and therefore more effective in accelerating the boat. However
this can take great strength and stamina and needs a strong arm and a good
technique to be able to execute it effectively.
Light Winds
As far as the hull is concerned, one of the major factors for going
fast in light airs is to reduce the wetted surface area of the hull. All
areas in contact with the water cause friction and hence induce drag on
the hull. When on a run sit well forward, sometimes even in front of the
traveller so as to bring the wide transom area out of the water. At the
same time heel the boat to windward. This reduces the overall area of hull
surface which is immersed in water. This extreme technique is only used
in very light winds. As soon as the wind increases, body weight will have
to be brought aft again so that the rudder has enough grip on the water
to be effective in steering the boat. Body motion in the boat should be
kept to a minimum as every movement will shake what little wind there is
from the sail. A steady flow of air over the sail is imperative at all
times. When on a beam reach or tighter, the boat should again be trimmed
bow down, but it should also be heeled to leeward so that the sail takes
up its natural shape.
Light Air - Reach
-
trim boat to leeward
-
open leech
-
keep still in boat
-
minimum kicker tension
-
use sail fullness to create rudder feel
|
The centreboard should be fully retracted when on a run, and only down
slightly when on a reach. As a general rule only put enough down to keep
the boat moving in a straight line. If too little is down, the boat will
tend to skid sideways. The centreboard still causes frictional drag so
use as little as possible. Another important device is a strong JC strap
to hold the boom out. Without one, the boat cannot be heeled to windward
on a run or broad reach without the boom falling back to the centreline.
In light airs the sail needs to be flat with an open leech. Little or
no kicker tension is ever required. A tight kicker would give a hooked
leech and would kill boatspeed and make the sail fold in on itself, making
it very difficult to fill and produce drive. Ease the inhaul to produce
depth in the foot of the sail and continually adjust the sheet.
Light Air - Run
-
centreboard fully in case
-
sail out to 90 degrees
-
body weight forward
-
steer by heeling and sail trim
-
hardly any kicker
-
tight JC holds boom out
-
heel to windward if enough
-
wind to hold sail shape
|
Medium Winds
As the wind increases more kicker tension is required to keep the leech
behind the mast. If the leech is allowed to go in front of the mast, a
twisting force is set up which can roll the boat into windward. However
if the rolling can be controlled, this technique, combined with sailing
slightly by the lee, can be fast. You must have twist in the sail to make
sailing by the lee effective. To induce twist in the sail ease the kicker
so that the leech moves forward and to reduce twist tension the kicker
to move the leech back. When sailing by the lee the wind flow along the
sail reverses and flows from the leech to the mast so a hooked leech is
not good as it offers a barrier to the wind as it enters the sail. To utilise
this technique your mainsheet must be long enough to allow the boom to
extend out to 100 degrees from the centreline. To gain a little bit of
extra length, let the traveller right out to the sidedeck.
Medium Air - Run
-
centreboard up
-
some kicker
-
boom out to 90 degrees
-
sheet direct from boom
-
heel to windward
|
In the increased wind move your weight further aft to gain rudder control
and to bring the bow out of the water (essential when it is windy enough
to start planing). The sail will need to be flattened slightly when reaching
otherwise the boat might prove hard to control. Tensioning the kicker without
flattening the sail will cause the leech to hook and that will induce weather
helm. This is alleviated by flattening the foot so that the leech opens.
Also the centreboard may need to be dropped slightly on the run to gain
stability, and on the reach to stop the boat slipping sideways. Continually
adjust the mainsheet. Ease it until the sail just luffs then haul in until
the telltales stream, then ease until the sail just luffs and then do it
again and again.
Medium Air - Reach
-
play gusts/waves constantly
-
use kicker to produce even luff
-
sit aft to bring bow up
-
slight tension on inhaul/outhaul
-
keep boat flat
|
Sail Shape on a Reach
On a reach the fundamental requirement is an even angle of entry of
the wind at the luff. Set up the fullness of the sail to match the wind
conditions and then adjust the kicker such that all of the luff tell tales
are flowing together - that they all lift together at the same time. If
the wind eases, there will be less force on the leech and consequently
it will start to hook and the sail will stall. Ease the kicker to open
up the leech a bit until the tell-tales are streaming together again. If
the wind increases, the extra pressure in the sail will cause the leech
to open up more (giving the sail more twist). As a result the luff will
not be aligned. Tension the kicker to bring the sail back into line, closing
the leech and straightening the luff. Whereas too loose a kicker can be
seen by the fluttering luff, too tight a kicker can be seen by the leech
tell-tales looking lifeless and not streaming. It can thus be seen that
on a offwind leg, the kicker needs to be adjusted almost as much as the
mainsheet in order to maintain optimum sail shape.
Priorities on a Reach
-
balance boat to minimise steering and drag
-
adjust sheet continuously to match wind direction
-
trim to leeward in light airs - otherwise keep it flat
-
sail trim - even luff shape, leech contains power
-
coax sail in gusts and lulls using kicker and sheet
-
obtain clear air and space to realise strategy
Waves
There will no doubt be waves around by now and the helm that can use
them well can make big gains over those helms that cannot. Basically the
technique consists of watching for a wave to come, steering (by trimming,
balance and perhaps a little rudder) to catch the wave, surfing down the
wave, loosing it and then picking up another. Always head for the troughs,
and you will always be heading downhill. If you head for the crests you
will always be heading uphill, which is slow. When on a wave, steer down
for the lowest point that you can see so that you are always moving down
a wave. If it is very windy you may find yourself ploughing into the wave
in front. Head up or bear away and pick up the next wave just before you
hit the wave in front. Hitting waves not only slows you down considerably,
but you also run the risk of a broach. If the wind is not quite strong
enough for you to keep up with the wave, you will eventually find the wave
overtaking you, the crest moving underneath the boat. Pump hard (maximum
3 times per gust/wave)to maintain position on the wave for as long as possible,
steering for the lowest point of water around you, so that you are always
moving fast. When you eventually fall off the the wave head up a little
and look for the next one on which a catch a ride, and then bear away again
once on it, pumping hard to initiate surfing.
Strong Winds
Sailing a Finn offwind in strong winds requires strong arms and quick
reflexes. Your primary task is to stop the bow burying into waves because
not only will this slow you down somewhat it also runs the great risk of
causing a capsize, which becomes more spectacular the further away from
the wind you are. So sit well back in the boat to bring the nose up. Play
the sheet constantly either from the boom or more probably direct from
the floor block, as this allows better body movement - you are not being
pulled out of the boat, just into it. The gusts need to be played on the
reach and the run. On a reach bear off to stay with the area of stronger
wind for longer; come up in the lulls to find the incoming gusts. When
on a run it may pay to come up slightly to promote planing in the gusts
and bear off in the lulls. Conversely in survival conditions it can pay
to bear off in the gusts to reduce the heeling effect and so gain better
control of the boat and also to head up in the lulls when you will be able
to control the boat more easily when planing flat out.
Heavy Air
-
keep sail fairly flat
-
half centreboard down
-
sit further aft
-
tight kicker - but avoid dipping boom in waves
-
let kicker off for the gybe
|
When gybing use minimum kicker and a flat sail to survive. With no kicker
on, the boom will be way above the deck and your head, and there will be
little power left in it. Also beware of too tight a kicker on reach. A
gust catching you unaware can heel the boat just enough to dip the boom
end in the water and flip you in. Whereas in some classes body weight can
be enough to 'lump' the boat upright again and bring the boom out of the
water, in a Finn this can be almost impossible. Therefore try to keep the
boat dead level or heeled slightly to windward and ease the kicker slightly
if you find the boom starting to skim the water. Waves just make the matter
worse of course.
Centreboard position is very much personal choice. As a rough guideline,
a 'safe' point to have it is when the top upper most corner is just going
into the case. More than this is usually unnecessary and less than this
make the boat hard to control in waves and gusts, but can be faster if
you are in control of the boat.
Downwind Speed
When sailing upwind, the boat that reaches the windward mark first
is normally the boat that has taken the best route up the beat as dictated
by wind shifts, tide etc - in short, by taking the shortest route possible.
Offwind, the speed of the boat has more importance than distance sailed.
Always steer for clear water and clean wind. Disturbed water and wind can
completely destroy downwind performance, so a route should be steered clear
of all other boats and obstructions. You may find yourself taking a very
roundabout route to the leeward mark but if you can maintain full speed
all the way while others are only travelling at 50 per cent speed you will
obviously get there quicker. With a constant wind always try to power up
the sail, by sailing by the lee, easing kicker and reversing flow, raising
centreboard and reducing wetted surface area. In a very shifty wind, sailing
by the lee can be slow because the boat will always be wanting to gybe
and much steering may be required to hold on the boat course. Better to
tighten the kicker and steer a higher course to maintain the wind in the
sail.
Going for it Offwind
The following attempts to point out some of the more obvious techniques
to enable mid fleet sailors to have a better chance of winning. A cheque
book will not be required just the enthusiasm to work with your existing
boat, rig and rudder. However there is a certain molecule that is well
worth getting hold of:- ATP or adenosine triphosphate.
Whilst the upwind slog invariably involves pain, the offwind leg, whilst
giving momentary relief at the windward mark, can offer more horrors and
pleasure in both legs and arms as the Finnster goes into overdrive to surf,
plane, pump and 'work' his craft to the gybe mark. To cap it all he might
even get puffed out.
Energy
Simply put, for muscles to work a copious supply of ATP is required
to facilitate the contraction of your muscle fibre(s). To produce a continuous
and adequate amount of ATP, a good supply of blood glucose and loads of
oxygen are needed allowing - aerobic glycolysis. It is not rare for the
muscle to run out of oxygen to some degree: ATP is still made but very
inefficiently by - anaerobic glycolysis, so you get less from your bag
of sugar in this way. What is more, when there is a lack of oxygen in the
muscle, a by-product builds up - lactic acid. This acid not only causes
cramp and pain, but uses up even more energy in your liver as it is detoxified,
so you get exhausted quicker. There is a very simple remedy to sort this
little problem out. You need bigger lungs and a stronger heart to collect
more oxygen and pump it more quickly to the muscle. Forget the glucose
tablets, it will arrive too late, but breathe deeper, it's your only chance.
Luckily it is possible to stretch your lungs and so increase the availability
of oxygen. Running, swimming, cycling, circuits, dancing or anything else
that increases the heart rate for 15 minutes or more is useful in this
respect.
To be really fast offwind you need to be mobile in the boat, often single
or two parting the mainsheet, then have sufficient composure to flip the
boat round at the gybe mark and set off on the correct tack on the next
leg. This all requires stamina, without which on a breezy reach you have
had it. This aspect of Finn sailing should not be lightly dismissed if
you want to do better.
Offwind Steering
The rudder is an obvious item to tackle. It would seem a good idea
to get rid of it! Rudders used badly have probably accounted for more lost
races and positions than any other bit on the boat. The reason for this
is that they become a first class brake when abused. The rudder needs to
be used in conjunction with all the other controls that turn the boat.
This means heeling the boat to windward (leaning aft too) to bear off and
heeling to leeward (and leaning forward) to head up. At the same time,
the mainsail needs to be trimmed: eased to bear off or pulled in to head
up.
If when steering you have weather helm it may be due to the sail being
over trimmed, boat heeling to leeward, not hiking hard enough or the centreboard
may be too far down. In any case the weather helm will be causing the boat
to slow, miss waves, be slow to get up on the plane and so lose distance
on the other boats. So if in doubt let it out. The sail!
Obviously the rudder does need to be used to some degree offwind, but
in judicious amounts relative to the wind and wave conditions. In light
winds the rudder should have no feel - a neutral feel with the flow
of the water passing across both sides of the blade evenly. To achieve
this, balance the boat by heeling it, steer with just the tips of your
fingers and keep still in the boat. If you wish to move do so by degrees.
Tactical situations excepted, move gently. If you are looking around, just
swivel your head, not your whole body or you will rock the boat.
In medium breezes, but before planing or surfing opportunities appear,
small waves will be washing against the boat and the rudder. In this case
the rudder should be allowed to wriggle with the altering water flow, the
tiller extension moving an inch or so either side of the mean position.
Again steer the boat with heel to maintain the strategic course and make
course changes with all three controls: sail, heel and rudder,
In high winds the need to be aware of outside steering influences is
vital: the gust that increases weather helm, the solid wave in front of
the bow. The key is anticipation. Ease the sail and heel to windward as
you bear off for a gust. Hike aft when a big wave threatens to turn the
boat into a submarine. Don't just sit there, move around the boat and keep
it balanced. In the lulls head up a touch and look for a dark patch of
water, indicating a puff.
Wave Technique
Catching waves takes precedence over minimal rudder use as the advantages
of being quickly on the plane offset those of rudder drag. However, bear
in mind the above for top performance. At high speeds the centreboard is
likely to cause weather helm and heel the boat, so pull it up to suit you.
The idea is to keep the boat heading for a hole so that it is always surfing
downhill. The boat needs to be dead flat, the helmsman working the mainsheet
continuously and hiking in and out to achieve this. Obviously there is
the panic down-helm lunge to prevent the windward wipeout in those moments
of concern! Remember at high speeds the powerful Finn rudder can have a
very dramatic effect on the boat’s course, so go gently. Ploughing into
the back of waves is a frequent hazard in a Finn. To reduce the damage,
head up, sheet in and lean backwards, helping the bow up and out of the
mass of water. Then head for the next available trough to start planing
again.
Pumping to some Finnsters may appear out of order, but it is a fact
of life on the International scene, so the top helms are going to use the
technique whenever the rules allow. Therefore we all need to learn how
to use the technique effectively, as bad pumping can do more harm that
good. It is not necessary to single part if you are not up to it: alternative
methods can be used. Up to three good tweaks of the sheet are needed, as
the bow bursts into space on a wave crest and at the same time moving your
body forward to drop the bow into the trough, trimming the sheet in for
the increased boat speed and then moving aft a little to keep the bow riding
just above the water. If you are surfing/planning with huge sheets of water
flying up off the bow towards halfway up the mast, you need to move further
aft!
Maintain the surf for as long as possible, essentially learnt by much
practice in the right conditions. Methods to prolong a ride include gently
snaking down the course on a really big wave, again with the combination
of heel, sail trim and rudder. On the shorter more confused seas try to
traverse the wave by luffing or bearing away a touch, but always away from
the highest mound of water in front of your wave. In this way when the
surf is lost you don't pile into a wall of water, screw round with your
boom in the water and capsize! Even if you are scared, maintain the aggression
and tackle the elements head on - no messing. If however you have run out
of ATP, sit right back, sheet in a bit and steer to keep the boat plumb
upright. If it heels towards you push the helm away; the helm to you if
the boat starts to broach to windward.
Essentially practice makes perfect on the technical side, but fitness
and agility are of paramount importance to keep going.
Gybing the Finn
Gybing the Finn is one of those manoeuvres that requires much practice
and is easy to improve with practice. However it is essential to 'visualise'
what you are trying to achieve during the gybe - where you should be in
the boat and what you should be doing at all times into the gybe, during
the gybe and out of the gybe. How you go into the gybe and how you come
out of the gybe is probably more important than actually doing the gybe
as this is where the mistakes are more frequently made. There are many
techniques for gybing the Finn. Pick one that you can get along with and
perform confidently in all conditions.
Boat Set-up
A number of aspects apply to all methods of gybing. The idea is to
perform the gybe without the boat losing any speed through the water, doing
it smoothly and with the minimum of fuss. To allow adequate space underneath
the boom the kicker should be slackened a touch. In strong winds this is
essential, as is sheeting in the boom slightly so that the leech does not
extend forward of the mast. If it does then the resulting force will try
to roll the boat into windward. A tighter kicker will give you more acceleration
out of the gybe, but with the disadvantage of a lower boom. A looser kicker
will provide a safer gybe but with less speed out the other side because
of the loss of power in the now open leech. With the centreboard, a compromise
has to be reached between having too much down so that the boat may trip
over itself and having so little showing that the boat skids sideways,
possibly rolling you in in the process if you are not quick enough to respond
on the helm. In general, set its position such that the corner on the aft
face of the board is just showing out of the case. This gives an extension
of about ten inches below the hull. The mainsheet system should be free
flowing and must not catch on any fittings or jam up in its own blocks.
When to gybe
There is only really one moment to gybe, if you have the luxury of
time. Gybe when the boat is going fastest down the biggest wave that you
can find. This will ensure that there is hardly any pressure on the sail
and it will be easier to haul over. Also when the boom extends out to the
new leeward side there will be very little force on it (providing you are
still moving down the wave that is), and the boat will therefore be much
easier to control while you sort out your position in the boat. On the
larger waves you may find the boom has reluctance to actually take up position
and the sail flaps along the centreline. This happens because you are moving
faster down the wave than the wind is blowing. Watch out for when you slow
down and make sure the boom is hovering on the side of the boat that you
want it to end up on.
Steering
Steering is a very important part of the gybe. In strong winds how
you steer into and out of the gybe can determine how successful it is -
i.e. if you capsize or not. You must steer positively through the gybe.
Don't hesitate or back out - this will invariably cause a capsize in windy
weather or a significant loss of speed in light airs. Sometimes it can
pay to steer a 's' shape into and out of the gybe when on a run. Bear away
hard into the gybe, swing round through the gybe and bear away again to
resume your original course.
Ways to Gybe
There are two principle ways to gybe a Finn. In one method you are
facing the boom as it passes through the wind, and in the other method
you have your back to the boom. The method you choose to gybe can be changed
depending on the situation you are in, although it is far better to stick
to one method and excel at that. However you may have to change technique
occasionally, for example in extreme windy weather or when crash gybing
to avoid another boat or an obstruction.
Gybing Facing the Boom
If you are sheeting through the block on the floor (and not direct
from the boom) then when gybing grab hold of at least one, if not all,
of the mainsheet purchases to pull the boom over. Don't try to gybe by
giving the sheet a sharp tug through the floor block (except in survival
conditions). Because of the length of the boom it can take a long time
to react to your pull and come across too slowly- taking it straight from
the boom produces a more positive action which is more reliable. In lighter
winds, when gybing from a reach to a reach, the boat can be rolled to windward
going into the gybe, thus making the boom fall down. Once the boom has
passed through the wind, roll the boat the other way, to the new windward
side. As the wind increases you will need to keep the boat flat at all
times. Only try to pull the boom across the boat once you have steered
round so that the wind is blowing onto your lee quarter. The technique
is therefore thus:
-
sheet in, ease kicker and point tiller extension away from you
-
bear away until wind is off lee quarter
-
holding the sheet directly from the boom, give a positive tug, pulling
it as far across the boat as your reach permits
-
as boom passes overhead move aft foot across boat, body facing forwards
-
with the tiller extension behind your back steer the opposite way out of
the gybe to the way the boat is trying to go - you will then follow a straight
course. If the boat is trying to spin into the wind (more usual), then
you must bear away hard to counteract it
-
move forward foot over, swivel body and then sit on sidedeck
-
drop the tiller extension, or sit on it, change hands on sheet and pick
up extension again. (In light airs the change can be made while standing
up after the gybe)
-
tension kicker, sheet out and adjust course
The main advantage of this method is that you can see the boom coming
and can time your movements and actions much more precisely.
Not Facing the Boom
This method is very different from that just described. First of all
you change hands on the sheet and the tiller extension before the gybe
is commenced. This means that as you come out of the gybe you are ready
to start sailing properly immediately and have little sorting out to do.
As a result your speed out of the gybe can be faster. Kicker and
sheet adjustments are the same as above.
-
holding the sheet straight from the boom, bring your tiller hand across
to grab it while
-
turning your back to the boom and and picking up the tiller extension from
behind your back. Keep the tiller extension pointing at the current windward
side.
-
pull the sheet and duck down so the boom passes over your head and across
the boat.
-
flip tiller extension to new windward side as soon as boom has passed
-
move backwards onto the new sidedeck and sit down
-
assume correct course
From this it is obvious that as soon as the boom has passed overhead
you have effectively completed the manoeuvre. All you then have to do is
sit down and carry on sailing. This gybe has often been dubbed 'the experts
gybe' in that it looks cleaner and done properly can produce a better result.
However it is much more difficult to get right and can cause problems in
windy weather because the boat has to be kept dead level throughout, while
you are facing the wrong way and unable to sit on the sidedeck. It is also
much easier to make a mistake and harder to recover from one because your
hands are effectively crossed. But practice makes perfect!
Sailing in Different
Conditions
The following short sentences are taken from an article on Stuart Childerley
in 1988. Remember them and understand why they are important.
Light Wind Technique
-
Mast rake at 6.76 on Stuart's boat. This will vary between individual boats
due to differences of mast position and transom height, but gives you a
starting point.
-
Vary the mainsheet continuously altering the leech tension all the time.
Leech exhausting parallel to the centreline of the boat, but trying to
bend the mast to start pointing up.
-
Outhaul approx. 4'' from black band.
-
Adjust the tack to pretty the sail up.
-
No Cunningham.
-
Only a small amount of kicker downwind.
-
JC Strap very tight.
-
Body weight in boat by the traveller.
-
Very gentle on the rudder movements.
-
Little or no plate downwind.
Medium Wind Technique
-
Mast rake goes forward to 6.78m.
-
Tension mainsheet and adjust traveller so boom is on edge of the deck at
the sheerline.
-
Outhaul tensioned a bit.
-
Tack near the mast.
-
Sometimes use the Cunningham.
-
A tight kicker downwind to maximise power.
-
Body just away from traveller.
-
Use the rudder a lot in the chop and to keep the boat level.
-
Minimum plate downwind.
Heavy Wind Technique
-
Traveller out more. Adjusting all the time.
-
Tack to the mast.
-
Outhaul to the black band - no further.
-
Cunningham on and off as required.
-
Kicker hard on downwind, but let it off for the gybe!
-
'Heaps' of rudder.
-
Body back to keep the bow from digging.
-
Plate down a little more downwind.
-
Enjoy yourself and take a pride.
Go Sailing
Now the boat is set up. All the figures given will obviously have to
be continuously fine tuned to find the exact settings that suit your body
weight, your hull and your choice of rig and make your boat go like a train.
What you have to do now is go out and do an awful lot of sailing.
