Here is one of the runs I got yesterday on Pittwater, Palm Beach. Super light (way under 10kts) and having a blast on the Hover 122 and Chopper XL (roughly 5.3m).
Sounds like all the big brands will be windsurf foiling in 2018. Naish is doing a windsurfing foil and board along with a small sails NeilPryde have their product on their website now...
I plan to GPS windsurf on windy days over 15 knots and windsurf/foil in the light stuff
Keep an eye out for pictures of these products from all brands on the web and please post here.
