If you like the boat in my avatar , i can tell you how to build one . It takes about one day to build and about one hundred bucks in materials. They are very stable in the water and only draw about two inches of depth. I use mine in the Kentucky river which is pretty calm. I don't know how it would work in high waves though, but I imagine much like other flat bottomed boats.It is easy to get it licensed. Simply call the water safty people and they will come to your house to inspect the boat. Mainly they say, 'Yea, that's a boat allright." They then give you a title which you take to the courthouse and get a registration and stickers. This one is twelve feet long, but I have made them as big as twenty feet.One thing I like about wooden boats is they are so easy to modify to suit your needs.If I can figure out how to post a drawing I will add it to my thread.
