No, windsurfers are NOT restricted to the trench. The current OPEN WATER world speed record is 44.35 knots..... faster than any cat has recorded over an official trial, anywhere.
Maxicats have recorded over 44 knots offshore, fully crewed and provisoned.
Someone in this forum commented that they might try the outright speed record, if they stripped the boat of everything unnecessary for the short sprint.
Also, Orange II is bigger and faster than the maxicat that recorded over 44 (Orange I, probably).
