Introducing: myboatplans – "instant boat building!" the complete boat builders resource. over 518 detailed boat plans, schematics, cutting patterns, material lists for all types of boats.. 1 sheet + is an attempt to make a nice looking, good performing small boat out of a single sheet of plywood. with a 30" beam and a length of 88", the boat achieves 4 mph with a trolling motor. of course it can be rowed and paddled too. costing about $100 to construct, and capable of a 6 foot 190 pound occupant, it can be many things to many people.. This is a pram dinghy i built when i got tired of pumping up the inflatable every time i wanted to get aboard the sailing boat i used to own. unfortunately, by the time the dinghy was completed i had sold the sailing boat, but it now get regular use in the summer on the local river..
