Got thinking yesterday and started working on a mathematical equation as to determining sail size. Wondered if any one else had done such before ? All sensible responses welcome then we can make a tested formula across all people... all publish it as an iphone application and buy a share house in pozo.....or not.
variables
Surface area of board (length/ width)=SA Fin size=FS Sail Size=SS Wind strenth (kts)= knts weight (body weight+equipment in mast, sail, boom , universal)= W Volume= V experience= E swell= Sw
Try and use the same abbreviations and see what people come up with.
I think there is too many variables. You need to take boardshape, sailtype, sailor preference( do you like overpowered conditions or just enough power), sailor strength, harnessline length, fintype and so on and so on...
I normally use 1 m2 larger than most others on same boardtype, sailtype and sailorweight, so i think it is hard to make a general formula. You could make one for yourself. But i think that it would be easier just to find out what your preference is.
