You can build your son or daughter a plywood canoe in a weekend. The simplest canoes are made of just 3 pieces of plywood: the two sides, and the base. More complex shapes can be created, but these instructions are for a simple canoe.
Step 1: Cut Out Two Strips
Cut out two strips of plywood 10 inches in diameter (25.4cm)drill a series of 4 holes through both, at each end. Use small cable ties to fasten them together.
Step 2: Get Your Child To Sit On The Remaining Sheet Of Plywood
Get your child to sit on the remaining sheet of plywood, and pull open the two strips of plywood, lifting them over the child's head and onto the plywood. The child can then decide what shape the canoe should be, by pushing the sides out. The wider the canoe, the more stable it will be on the water.
Step 3: Hold The Sides Carefully
Hold the sides carefully, and get someone to draw around the shape on the bottom sheet of plywood.Cut out the bottom of the canoe, and fasten it to the sides with the cable ties. Put the "tails" of the cable ties on the outside of the boat.
Step 4: Use Polyester Resin
Use polyester resin and 2 inch (50.8mm) wide glass fibre tape to seal the seams, starting on the inside.
Step 5: Turn The Boat Over And Cut
When the resin has dried, turn the boat over and cut off all the cable ties. Use an electric planer to tidy up the outside before using the resin and tape on the outside seams. A small deck can be gunwhale.
Step 6: Work Fast
Work fast. You can complete the whole job in a weekend, and be on the water on the Sunday afternoon.
