The Jupiter Point series of kayak designs are intended as easy-to-build, fun-to-paddle, versatile collection of kayaks. With a simple 3-panel hull and unique 3-panel deck, the boats are quick to assemble, have a lot of character and perform very well. Plans are currently available for Ganymede a 13′ recreational kayak that uses 3 sheets of plywood. You can download free plans from my website: http://bit.ly/xde8Bz
The preferred material for this construction is 4 mm thick okoume marine plywood, covered with a 6-ounce per square yard fiberglass cloth coated with an epoxy resin. This will provide the strongest, longest lasting construction, but if you are strapped for cash, you can substitute lauan “door-skin” for the okoume and polyester resin for the epoxy. Lauan is apt to have gaps in the interior veneers that make the plywood. These gaps can weaken the material and may accumulate condensation leading to rot, but with a little care in building and storage when you are done lauan can make a nice boat. The description of techniques in these instructions assume epoxy resin, you may need to adjust your technique if you opt to use polyester.
