Rick- you have the best avatar
I don't know of anyone who sells or even has a set of blueprints. The outside dimensions are not that hard to figure. Bigshrimpin went over them a little in his thread. The important measurements are the transom height, bracket set back (length)and transom angle. You build around those numbers. The bracket I'm working on now for my 20sf is the third bracket I've either built or helped to build. All three of those brackets have different dimensions. The bracket on my 23 seacraft has a 29 inch set back and the brackets for the 20 seacrafts have a 26 inch set back. The flotation chamber on the bracket I'm making now has a slightly narrower dead rise then Tims so the sides of this bracket are taller then Tims. what I'm trying to say is that there are lots of ways to skin this cat. Pm me if you want and I can go into more detail.
