I have already had experience in building boats "Skif" of wood. As a result of its use, I wanted to make the boat as light in weight and with the possibility of storage under the bed or under the wall in the garage.
Teachers! Did you use this instructable in your classroom?

Bring to your attention the process of building a folding boat made of polypropylene own design. The boat was conceived light, compact, reliable - stability, maneuverability and ample. I sailed on a boat over 300km and is fully satisfied with the result! Boat weight about 40kg in the assembled form. Board height 50cm, width 1.20 m, length 3,75m. Transported on a car roof. Very stability. Under the motor 3.5 hp with 4 people on board is 10km / h, with one person speed of 12km / h. Going on shore in 9 minutes.
When folded, the boat is a flat pack size 4 * 0.60 * 0.05 meters. Paddles and fin fit inside, sitting separately.
To build the boats need 4 pieces of 5 mm thick polypropylene. I chose 4m long sheets of them to get a boat length of 3,8 m.
First marked out the pattern on the sheet and cut out using a jigsaw. Next, using the manual milling machine cut grooves along the edges of the sheet to be able to bend side and bottom that allows you to fold the boat. Milling depth of 0.3 mm slot width 5mm.
Further, the sides and the bottom are connected by means of bolts and nuts. Between the sheets used sealant. Assembly of the half boat check for leaks, collect water inside. Leak should not be. Next, connect the two halves of the boat and check for leaks again.
In the boat has three seats. It can is 4 people. Aft transom mounted to the motor. The seats are attached to the sides of the bolts. Under the seats installed units buoyancy foam. Under the seats and floating keel blocks is inserted to enhance rigidity.
General view of the patterns represented on the photo. Good luck!
And now the boat with steering and remote control gas and reverse.
Files with the plan board, and the bottom of the seat.
