The PDRacer is a developmental one-design racing sailboat that is basically a plywood box with a curved bottom and is the easiest boat in the world to build. The rules are aimed at keeping the lower 10″ of all hulls the same but the rest is up to the builder.
A simple hull can be made from 3 sheets of plywood, Titebond II glue, and latex house paint. If you work hard for 2 weekends you can go sailing on the 3rd weekend. If you are really in a hurry it is possible to go from lumber to the lake in 5 days.
