I had decided to build a canoe before the pandemic hit, just a coincidence in timing. The idea was to build something that would be light enough for my daughter and I to get on and off the car by ourselves so we could go paddling and fishing more often. It also had to be simple enough for me to build with a minimum of tools (and experience) in our carport... Well, at least I kind of got the last part right. I settled on the "Quick canoe" after watching a Youtube video.
It is basically a few pieces of plywood stuck together with a few other bits of wood added here and there.
Sticking the bottom pieces together, the side pieces are next to it.
The sides held in position with temporary thwarts.
The bottom and sides held in position with duct tape and a few zap straps. This process would have worked better if there was also some framing near the joint.
