Not sure what you meant by the incorrect answer, but my original is correct - a quick call to FW has confirmed this. Only Disney owned canoes and other watercraft are allowed, with the only exception being the boats owned by the concession people who handle the parasailing.
FW guy, I think what he meant by "wrong" answer was "the answer he did not want to hear". Or the answer he didn't like. I know sometimes the only answer I would consider to be the "right" one is the the one that I want to hear.
