And these cats clip along at 40 knots with retracted centerboards.... I think the term daggerboard refers to day sailor mono hulls.. Haven't heard them called that in years..
Grew up racing Hobie's just bought another one last week, also have a laser. Fully understand the benefit of lifting the windward daggerboard to reduce drag and wetted surface.
The word asymmetric threw me off but I stated, "If you mean catamaran sailors lift the windward daggerboard then I think I understand but both rudders and daggerboards are the same size."
Thought you were indicating that nacras had one board shorter than the other, my mistake.
Also, many beach cats and performance dinghies have daggerboards not centerboards, and that includes the AC45's and AC72's. Daggerboards go through the hull, centerboards pivot into a pocket in the hull. The Hobie 17's and 21's have centerboards but the Hobie 18's, 20's, Tigers, and Wild Cats all have daggerboards. And while incorrect even Nacra describes their centerboards on the 5.8 as "kick up daggerboards." Tornados do have centerboards.
Not trying to troll, just got confused by the reference. Good luck with the fin experiment. Also, another AC45 race next month. It was cool watching the races from the shore a few weeks ago.
