ok, thanks for the advise, ill add 1 more stringer to the side and another one on the bottom. you are partially right, the plans had a round bottom on it with no keel , but i altered it to a shallow V ,at 3.5 degrees and i rounded the chine slightly, thought that would give it a little more stability, in the rougher water that ill be running it in. When i get started with the frames, right now I've just cut them out of foam core just so that i can see how will work out before i cut any plywood. ill post a few pics, when i get started assembly.
