We fished gheenoes alot. To me the gheenoe is a stable boat after fishing in canoes. It just takes a little consideration and balance. Small boats of old were not very wide in comparison to modern planing hulls. I think this is where comparitive stability attributes or the lack of gets lost a little.Coming from a canoe to a gheenoe, makes the additional stability apparent then from coming from a 17ft Mako down to it. Jet ski's are tippy,kayaks are as well. But once you get to using them,they in effect become part of you from familiarity. Seems like one's body involuntarily compensates after a spell.
If one thinks about it,the same could be said for, lets say, "rollerskates".
