I'm not a trained Marine architect, but I believe that rafts are quite stable, though they do have two stable modes (not unlike my small sailing catamaran); right side up and upside down.

Having personal experience on the Charles River and coastal areas of the open ocean, I'd suggest that conditions on the open ocean can provide a more severe test of craft stability than the Charles.

Oh, yeah. I still think Heyerdahl was nuts. Great story, though.
