Arrived when the wind was a bit strong, but most people where changing from 7.0 to 7.8 :(
Quickly rigged the 8.4 (still no F2017...) and hit the water with a lot of non-planing windsurfers.
Got some decent gusts, after 30km wind picked up and 7.0 would have been better, but had to leave quite early....
Last 20min I tried the SL-X 37cm in less wind, fin length was fine with 8.4 to my surprise... Maybe I'll try that again next time :)
