It’s summer and the canoe has been placed on the roof of the car for convenience. My canoe (we all have one here in Canada) is narrow, fast and very wobbly. It was made for solo paddling, but I converted it to a two seater. At 30″ wide it’s about 6″ narrower than most canoes and it can feel quite unstable. So I did some research on homemade outriggers and the other day I ran all over town and got what I needed. It wasn’t that difficult and it has made a major improvement in the boat. We tested it last night and found the canoe to be much more stable, but with no discernible drag. The pontoons are set just above the waterline, and they dip in on one side then the other as the boat rocks, enough to create stability without ill effect.
I made a manual in case anyone here wants to make their own. Have fun and let me know how it works for you. Please note: this has not been certified, rigorously tested or engineered for safety. Use at your own risk, and be careful!
