Anyone here ever built a boat?

I’m short on foam, and feeling less and less enthused each time I’m working on a surfboard. I have enough foam for a special board for a special friend, plus a fish for “disposal”… Then I’m kind of looking for a new project, a little break from boardbuilding, a new challenge as it were.

I was looking into those plans you can get to make trailerable sailboats out of plywood and stuff…

Anyone ever do anything like this?
