Puddle Duck Racer-Simplicity Is The Essence Of True Beauty 
Officially speaking, there are no plans, only a hull shape that you must conform to as specified in the rules. You can build the boat any way you want, the most common and easy method is the "nail and glue" method where you use a chine log to join pieces of plywood. For a pictorial of how this is done, see the Building Bucket Ears article. The PDRacer is a one design racing sailboat that is basically a plywood box with a curved bottom, and is the easiest boat in the world to build. Free plans, free club, all boats must have have the lower 10" of their hulls be alike, but the rest is up to the builder. You can put any type of sail rig or underwater fins that you wish. Also the interior and deck above 10" is completely up to you. Many Other Uses: Not just for racing, this is a great boat to use for recreational purposes - and in most states a boat this small does not need to be titled or registred. The hull shape carries 630 lbs, and if you build it with the simple bow and stern airboxes, there is lots of room in the center for people and gear.

Daytrip Canoe: The canoe can be build from 3 sheets of 6 mm plywood and can easily be transported on a car roof. It easily loads two adults and a large picnic basket. The stitch and glue building method will be an obvious choice. I would figure that the canoe could be built in 2-3 days. It will have a hull weight of approximately 25-28 kg.  download canoe.zip  Need Viewer. Touring Canoe:  If the need for a canoe is for longer trips on lakes and rivers this canoe is perfect. It is a large canoe and it carries all your gear when your plans are to stay long time on the water. The touring canoe can be build from 4 sheets of 6 mm plywood. It is mainly an enlarged version of the daytrip canoe so the building method would be the same. The time used for building would be 3-4 days. The hull will have a weight of 32-35 kg. download touringcanoe.zip  Need viewer.
