Objet : Re: CR du FW speed session du Der le 10/04 par pepewind sur 30-04-2009 11:56:29 pour info, en lisant un article (en anglais) mentionné ici, il n'y a pas très longtemps : http://www.carbonsugar.com/technique/how-fast-can-your-fw-kit-go/ en rapport avec vitesse en Formula et platitude du plan dl'eau : "... It has long been said that the best setup for sailing formula (FW) kit at its top speed potential is to have: * tiny sail * tiny fin * dead flat water * lots of wind * balls of steel! ..." "... So in actual fact, the conditions needed for a super fast FW speed should be: * powerful sail (10m/11m recommended) * small fin (+66cm at least, but powerful enough to help rail the board) * lot's of wind (+25 knots mandatory) * relatively flat water with small, close together chop (we'll get to this in a minute) * balls of steel! ..." et sur la platitude du plan dl'eau... : Chop, Not Flat: Believe it or not, small chop helps your FW speed by increases the board's ability to rail downwind. On a speed strip, with ultra flat water it is more difficult to rail the board and keep it railed. Dennis Littel commented after his famous day that his fastest runs were in the small 20-40cm chop away from the smooth bank he had been running along. The board would be easier railed, which allowed the sailor to concentrate on his stance and sheeting, to keep the board trimmed and fluent through the water. The closer the chop is together, the more this will help. In strong winds this may be a dangerous combination for some - but you have already signed your life away by wanting to get a FW board over 30 knots !! ©carbonsugar.com |
