I’m not convinced the extreme narrow boats with tumblehome are all that desireable. Seems to make them a little rocky in heavy waves, the opposite of what you want. My Magic can make my behind pucker if I’m battling wind. I’m used to it, but I don’t remember having the same amount of trepidation and gnashing of teeth with more standard hull designs. That said, I don’t remember paddling a large canoe with excessive tumblehome.
