Hello Roy, I never did like leeway either. On the kproa models, I found that if the sail's center of lift is far enough forward, the keels can be placed at a...
Hello Malcolm, The windward hull on a kproa, as currently configured with vertical keels and an 80%/20% windward to leeward hull weight distribution, will rise...
Hello Todd, Yes, I tried a moveable parallelogram to get the sail forward and, as you, abandoned it as too complicated for use on a full size craft. In my...

Aka is the structure between the vaka and ama. (Vaka) main hull usually leeward on pacific type with (ama) being windward hull. Sometimes I confuse windward...

The only way I can keep these term straight is thinking that an aKa is the Kross-arm and the aMa Meets the water. ~Greg On Tue, 01 Mar 2005 13:54:40 -0000,...
... To put it another way, 75kg of reserve ama buoyancy on a small proa might create a high-buoyancy ama; 75kg of reserve on a big proa would be considered a...

Hi Peter. If wind speeds in your area is high enough see no reason why you cannot go fast. I am no expert but think 10knots fairly easy, 15 knots yes if a fast...
