I weighed 130 lbs when I was 14. I'm close to double that now. If I just shift my butt 2" to the left, I tell my canoe companions to lean right.
We had everything from a 10 footers to a 26 footer to play with. Six in all. The 26’ was almost impossible to flip. Four foot wide and it would handle a 20 hp motor just fine. It was meant for guys your size.
