A guy in our marina had one he kept on the boat with him. Poor boat had belonged to some friends of mine before he bought it, and he and the dog basically ruined it - not the dogs fault. He also took it offshore with him, but one trip he couldn't find the dog after he tied the boat up!Figured it went back in the cockpit and fell or jumped overboard a few miles out. He immediately drove to the beach, found it playing with some kids a few miles from the jetties, where it had swum ashore!

I should mention the old boy drank A LOT!
