Hey Dave,
I hear you loud and clear on the appeal of building your own boat. For a while I was building one every winter, just for the fun of the project. And of course this all falls in line with why we are all on this forum for TRADITIONAL archery, celebrating the unique challenges and character of lower tech, more hands-on equipment, some folks building their own gear from scratch.
It's the difference between a home cooked meal and McDonalds, isn't it?
I'm sure you will have a lot of fun with your boat (whichever one you decide on) well before it gets wet. In fact, it has started already.
