RE: Kits or scratch plans?
There are several threads on the "Wild Thing" in this forum. Look them up. I built one a few years ago and I can attest to the capability and speed of the boat. However, it is not a boat that you want to run in rough water unless you throttle back a lot. As I alluded to in my previous posting, get some good quality marine grade plywood from someone like Lone Star Balsa or National Balsa. Don't try door skin or light ply. You'll be back in the Dumas category if you do.
