Where did you got that side plate of it Larr? Very good, Got a larger one? Well, hull is the simplest part of this babe. Dead ride angles, keel, step, planing angles etc. On the boat side I'm safe, on the wing side..... the story is quite different. I am currently lofting the keel (hull) to a 1:1 plan. Will start cutting assembly soon. ( As I said before, boats are easy) Anything Larr, anything you can input would be appreciated. calculating swept at 11 degrees.
