Josh, if you're seriously looking to build a bigger boat similar to this, have I got a deal for you! I have a, (I believe), full set of plans for a 16' Devin Scaup. They were given to me by Capt. Jack Passie a few years ago. At the time, I had every intention of building her, but things happened beyond my control which eventually squelched that idea. I'd be willing to "pay it forward" IF, you were to really use them.
It's a lot of work, but I have a boat I built from scratch, a Zack Taylor Widgeon, and I'll tell you, there is no telling how much satisfaction you will get out of hunting out of a boat you built with your own hands.
