Great discussions as always.
The more I think about the more I am convinced that what windsurf racing (including the olympics) needs is Formula 1.2 (1 sail, 2 boards). Take Starboard's FOD and add a serenity and you have close to the ultimate wind powered racing in <25knots for the rough equivilant cost of the rsx and much cheaper than formula.
Look at James' great chart - Formula + Serenity is the best racing for those winds. (I hope you don't mind the link James!)
