Organisation/ISAF Windsurfing Trials/World Sailing Games Reports

STUDY RESULTS ON FORMULA WINDSURFING CONCEPT

Made by Pascal CHAULLET  National Coach, Responsible for Windsurfing organisation

This study ,which was ordered by the French Sailing Federation regarding the Formula Windsurfing concept, is divided into three parts.

  1. A study on the equipment concept under racing conditions over two events – ISAF WORLD CHAMPIONSHIP IN MARSEILLE and the FRENCH QUALIFYING EVENT For the ISAF WORLD.
  2. A study on speed polarities for the present Formula Windsurfing equipment.
  3. A study on Weather conditions met on the Peking Olympic Games site.

The purpose of this study is:

To evaluate and measure the technical characteristics of this equipment ( Speed/direction)

To determine advantages and inconveniences  within a sport structuring possibility and within an Olympic bid proposal .

To evaluate possibilities to present this concept for the Peking Olympic Games.

Hereunder results is the first summary for N° 1 part – A full report will be presented on November. Part 2 and 3 will be followed by Didier Flamme.

Human and technical means to realise this study are the following:

Observers team are including: An engineer Paul Iachkine, A video specialist Lionel Cottin, Didier Flamme CTN and Pascal Chaullet National Coach heading the Windsurfing National structuration.

Measurement and watching tools are video cameras, a meteorological buoy anchored before and during racing to permanently measure direction and wind speed , GPS to determine the racing surface limits and Speed/direction compromises.

The one Design Equipment used was : one board, two fins and two different rigs see details.

First statement on measures and observations:

Courses:

Ten courses have been raced within four days over nine regatta days as follows:

One day cancelled for all racing series du to strong wind

 One day cancelled due to lack of wind to the exception of J80 and J22

 Three days cancelled due to insufficient wind for the Formula Windsurfing

Racing area surface is very large due to the widely open angles on the windward leg. Raced distances are of about 2 miles for a 0.7 mile upwind leg. Racing areas are so large that it is advisable to make use of a Windward/Leeward  course rather than a trapezoidal course for inter series regatta.

Equipment:

Many broken masts but nothing happened on the water. Although the board is perfectible, the one design equipment was of good quality. Sizes and number of sails are in line with an adaptability target for a large number of potential users and also the equipment limitation.

It is not possible to make a long term equipment viability  statement considering the short utilisation period.

Coaching statement:

Coaching on water  is more difficult due to the large racing area surface used, board speed and course duration. It is more difficult to over watch a race from the beginning till the end . The coach duty is somehow modified by the many technical details linked to tuning and also sails and fins replacements. Coaches interventions take a technical dominance. It is quite difficult to back-up more than two competitor, to back-up two different series, men and women is not satisfactory.

The sail choice is determinant and competitors may be conducted to call an assistance boat. This is a problem we have to think about and regulate.

Racing condition:

The wind ideal conditions for this equipment stages between an average of 10 to 15 knots ( Ref the Meteo buoy ) . For stronger wind sailing is time being very difficult with the larger sail and generally for women. Over 20 knots sailing is merely possible for few competitors only.

The main difficulty is staying with the wind speed and variations which may jeopardise sailing if fins and sails sizes are not matching.

However there is a large progression margin regarding equipment adaptation, tuning and evolution of the large sail, competitors technical level under such perfectible conditions.

Above elements may let us think about a very quick equipment or competitors adaptation for sailing under superior or equal weather conditions and rough sea.

Low wind speed range is far more problematic since it has not been possible to validate races with an average of 10 knots( see measures ref.).  Under these conditions the number of competitors together with wind variations  are unfavourable elements for sailing with a wind below 10 knots. Board speed estimated ( GPS ) would be 3 knots for a wind of 9 knots hence reaching the Laser performances, upwind route angles may go down as much as 70 to 80° from wind direction.

Under above conditions, speed differences linked to planning or not acquisition conditions are leading to considerable gap between competitors ( differences can be up to one mile on only one upwind leg )  therefore leading to inequity .

Concept development

In view of short boards development  ( without centre board ) , this concept seems to be adapted to a mass practice.  The One design concept answer the necessity of low costs  and equipment restriction. It encourages the individual adaptability to the equipment  and puts limits to over equipment.

As regards to women this concept is for the time being not adapted to  mass practice taking into account the existing population.

Within ideal conditions 10/15 knots it is particularly efficient, good for recreational  activities, rapid and attractive. It needs very strong lower limb  muscular qualities and people of a higher and heavier dimensions than for the actual centre board equipment.

Tacks and gibes are costly  which gives to courses a strategic prominence to the detriment of tactic. Rigs and board speed do not favours a fine perception of wind variations  in its direction. In view of a practice at high level, it should be wished to consider an initial formation on equipment which favours the tactic basic knowledge such as Optimist, Laser or Centre board Windsurfing.

A more detailed statement  will be presented in November , it will compile all data and measures  together with observers reports.

Wishing you a good receipt , I stay at your disposal for any explanations or complementary information.
