Another thing that makes boards fast is weight, this weight gets more important in lightwind conditions soo I found. This could also be translated to lightweight boards are important for extreme efficiency windsurfing, I believe this is true. At least it works really well for me and my sailingstyle.
There is always a balance between board/fin/sail for vertical lift. There are lots of compromizes possible, but this is what I prefer (for speedsurfing only):
- Sail lifts the surfers weight for 50-60% or even more? while putting another 10-30% on the mastfoot? (these values are not measured, a very rough estimation)
- The fin lifts out the boardweight from the mastfoot and behind+ maybe 10% riderweight.
- The board also will need to generate lift, but I prefer for efficienct to sail the board as much as possible out of the water.
- Begin April 2010, sailing Patrick van Hoof his 4kg? 100liter Sonck board, this was a really interesting experience...
- 22 May 2010, sailing the fanatic ray 140 liter, 9.5kg
- The 2009 and 2010 fanatic falcons (I never measured) being heavier than the previous ones (at least it feels like)
- I read somewhere Antoine Albeau believes the JP boardconstruction is the main reason for their performance. Only thing I don't understand why 2010 JP boards are heavier compared to 2009. Starboard is now lighter in the 131 liter size, and looking to Korea results with 2 starboards in top-3..... It was a smart thing to introduce the woodcarbon, innovation in boardconstruction might be the key for next years.
