How To Build A Plywood Canoe

Picture of How To Build A Plywood Canoe
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.

I would strongly suggest that anyone considering coating their canoe-boat with polyester resin should read up on it. I didnt when coating my canoe which resulted in the resin bubbling and flaking of. I later found out that this a condition called "Osmosis" due to the fact that polyester resin isnt waterproof. The sites that I have been all recommend " epoxy resin" which though more expensive does the job and lasts if coated with a UV protector such as yacht varnish or marine paint. Sorry to be a party pooper but I am having to strip mine and redo it after only on summer. my comment is only meant to helpful and possibly save someone from repeating my mistake, Space Alien.

A picture of a girl, however cute, in a canoe and a picture of a can of resin do not an instructable make. Like wrivera6 said, this sounds like a cool project, I would have liked to see pictures of it being built.

It would have been great to see actual pictures of you building the canoe. I would like to see how you cut and fastened every piece of plywood before you applied the resin. It looks like a great weekend project.

I did this, it was really fun. You should try it too. But it does take long.

Not trying to be rude or poke fun but when you say "Cut out two strips of plywood 10 inches in diameter" I think you mean width not diameter as diameter refers to circles.
