Is that yours on the car? it looks like its 90% structurally finished.

This web site is full of show boats and you can just use it the way it is for now. Get a foam seat and store back band and just use it. When You get time you can sand it out, do some hatches etc. Unless you have 0 interest in paddling. My point, is to just enjoy life and use the boat once in a while and don't worry about completing a show piece. (just an alternative suggestion)
