The only thing to add would be that we built our two "Petrellas" at 95% size, but full length. Also, the knee bumps look like bump outs, but they really aren't. We made a sharp drop in the strips in the area of the cockpit front, flowing toward a low rear deck. The sharp drop gives the illusion of a bump out. No problem with keeping the akiulisaq or tuiliq in place on the ocean cockpit.
