IFA Clinic 9-12 September 2003,
Cadiz
Arif Gurdenli

The 2003 Finn
Clinic took place in Cadiz just before the Gold Cup, with participation
from China, Japan and France.
The program had
intensive content, both on shore and on the water. The mornings were
covered by classroom work, where Luca Devoti, Ben Ainslie and Sebastien
Godefroid were the guest speakers.
On the water
(2-4 hours per day) sail trim, speed testing, boat handling drills (mark
rounding, tacking, gybing), start drills, short races were the focus
areas.
Luca's lecture
was on boats, rigs and tuning : all the secrets for a fast Finn. (9th
Sept)
Optimum weight
for a Finn sailor
These days the
optimum weight seems to be around 103. This may be down to 95 as minimum,
and up to 115 as max. to be competitive.
Centreboard pin
position
In general,
heavy guys can move the pin forward where the lighter sailors would prefer
to move it back. Also in light winds it would be faster to move it forward
and would be faster to move back in heavy winds.
Deck ring
position
Considering
Devoti boats, 1 big + 1-2 small pieces of blocks would be ideal in from of
the mast ring. In heavy wind the ring can be placed more forward and in
light winds could be moved aft.
Mast rake
More technology
is involved in the rake measurement. A tape is still used but a weight
system seems to be more accurate.
With a tape,
6.77 metre would be an average rake. Using a cord of leach length where an
electronic scale is attached at the end, boom is positioned on deck and
the load is measured as 37 kg for an average measurement. This can go down
to 32-33 kg as a minimum (by raking the mast aft).
In flat waters
and light winds you can rake the mast more back and in choppy conditions
more forward.
Mast types
Two type of
masts seem to dominate the class these days:
a) Diamond
shape; can deliver more consistent masts according to the required
measures. Since the shape is more symmetrical and the draft position is in
the middle, it's easier to build the mast to the numbers. Also the centre
of gravity may be slightly lower. These masts have quick response (more
nervous)
b) Teardrop
shape; may have a better aerodynamic shape to produce a narrower angle of
attack on the sail. This type of masts is more difficult to produce to the
required numbers. Therefore, would be vise to get the numbers of already
built masts and choose in between. These masts are slower in reaction.
Mast deflection
Most sailors and
sailmakers test the masts by supporting the mast at the bottom and at the
deck ring, then by attaching 12 kg at the tip.
Fore/aft
measures:
Tip deflection
(difference of mast tip position before attaching the 12 kg, and after
attaching it); 49 cm is stiff - 52 cm is on the softer side.
Middle
deflection; 110 (stiff) - 125 (soft)
An all-round
mast (fore/aft); 86 mm at 1/4 - 117 mm at 1/2 - 86 mm at 3/4 with 51.5 cm
tip deflection
Side to side
measures:
Tip deflection;
37 (stiff) - 42 (soft)
Middle
deflection; 115 (stiff) - 130 (soft)
3/4 deflection;
90-93% of middle deflection
An all-round
mast (side to side); 127 mm at 1/2 - 92% at 3/4 with 39 cm tip deflection.
Sails
North Sails have
a firmer cloth and is built for relatively stiffer masts.
Victory Sails
have softer clothes, need more mast bend in the middle.
In general, best
would be to decide on one sail and stick with it, since the feelings are
very different.
1 mm of change
in the mast curve (by the measurement) may result in 0.8 mm change in luff
curve of the sail.
Many thanks to
Luca.

Sebastien's lecture
was on fitness: must do for all Finn sailors. (10th Sept)
Balance seems to
be the most important idea in the physical preparation. In sailing certain
muscles work more than the others and they are more developed. During the
workout program, it's more important to focus on unused parts of the body,
to develop those muscles. This will result in a better performing body in
the long term (over a busy season)
Before starting
a training program it's very critical to find a good physio man who can
analyse you, your movements in a Finn and can come up with a specific
program to your needs.
In general,
before developing your most needed muscles in a Finn, it's necessary to
develop the opposite muscles to those.
Resting is a
very important aspect of the total preparation. When the regatta season is
over, one month of resting (in October) , with little exercises would be
good.
In November,
starting a heavy physical training with 3 sessions a day, 6 days a week:
Program type-A
(in a day)
1st session;
cardio by 2 hours bike or 1 hour run
2nd session; Gym
for about 1.5-2 hours.
3rd session;
Trunk (upper body) workout
Program type-B
(in a day)
1st session;
cardio intervals (focus on speed - explosion)
2nd session; gym
for about 1.5-2 hours.
3rd session;
stretching
In December,
include sailing in the training program after the cardio session in the
morning. On sailing days, gym work can be combined with trunk workout
after sailing session.
In January, it's
good to travel to warm countries for more on the water training and
regattas. Less cardio work and opposite muscles workout (heavy weight less
reps) in the gym should be integrated in the program. Longer sailing
sessions replace cardio time.
In February,
training type turns to speed/quick and active sessions in gym and cardio.
On the water focus on short racing and start drills by doing your best
(maximum effort) for shorter periods. Closer to the regatta season focus
more on the shorter, quicker training style with more effort in a shorter
time interval.
Sailing season;
focus on 3-4 major regattas (like Hyeres, Europeans, Worlds). Train really
hard for 3 weeks before your important regatta. During your important
regattas stop your cardio and gym work. In other regattas, gym and cardio
work should continue as before. Therefore, it's important to find a good
gym as the first thing when you arrive at the venue.
Between
regattas, take a rest, by sailing just 1-2 times a week. Fitness training
continues.
Heart rate: Keep
track of your heart rate in the night. If the difference between night and
day is high, you're doing well.
Nutrition:
Strong breakfast
with lots of carbohydrate is essential.
No fat before
sailing.
Lots of drinks
during sailing, especially in light wind and hot days. Rehydration
specific drinks are good in such days. In long days of sailing, energy
drinks can be included as well.
Protein rich
meals could be eaten 30 min. after training.
Carbo intake is
necessary during gym training.
Many thanks to
Sebastien.

Ben's lecture
was on Regatta preparation: should be considered by anyone
with big goals (11th Sept)
For a good
preparation of an important regatta, logistics are very important. Finding
a good place to stay, a gym, restaurants to your taste, nice pubs etc.
that can make you feel relaxed after a long and stressful day is needed.
To get used to
the conditions, three weeks would be a good time in advance. More than 3
weeks would be boring and cause demotivation during the regatta. During
the three week period, focusing on wind patterns, wave types, small
racing. Spending 3-5 hours on the water is good enough.
If you really
focus on the regatta, coming to the same location and training 3-5 months
before could be very positive. For the 2003 Worlds, Ben was in Cadiz in
March.
Extra info by
Ben
Few things to
consider in downwind :
- After rounding
the windward mark, do not gybe too soon. This will help you in keeping
clear wind.
- Boom vang
tension is more crucial on reaches than on the run.
- Keep 1/4 of
the centreboard down on the run, where 1/2 could be down in reaches.
- Using the
rudder is very slow downwind. Keeping the balance of the boat while
playing the waves to have minimum rudder action is very critical.
- Planning down
the wave, keeping the boat flat or slightly to leeward seems faster.
Many thanks to
Ben.
