When you are upside down the tumblehome acts like flare, secondary
stability for being upside down ;-)
I've got a canoe with extreme tumblehome. It's about the least sea
worthy craft I have ever paddled. 6 inch "waves" scare me. On
one occaision I encountered motorboat waves from the beam, the canoe slipped
sideways and dipped in one of the wings (the tumblehome is severe enough to
come to a point), the wing stopped the boat from side slipping and quickly
dumped me into the water. The canoe the righted itself, with virtually no
water getting in - just a quick "out you go" for the paddler.
If you care to see a similar extreme tumblehome design
