Re: Boat for rent, would you do it?
Nope never and any true friend knows better than to ask such a silly ? That's why in 30 years of boating it has never happened. Anyone who knows enough about boats knows that's a stupid idea to begin with!
Really? I let all my boating friends and family know they are welcome to ask to borrow mine (but not rent). I am not stupid, either.
Like everything in boats, it's all situational.
But one situation that will not occur is criminal charges against the owner who rents out his boat. Civil liability will be unlikely, too, although they may take a poke at you--until they learn there's no insurance coverage. The only way the boat owner could be civilly liable is if he does something negligent in the renting itself: rent to a visibly drunk guy, rent to an underage person, rent a boat that has something wrong with it AND that problem is the cause of the accident (example: no running lights. Wreck at night, you have a problem; wreck in broad daylight, probably not.)
But still, we can all agree that it is not worth the risk to rent to a stranger; you shouldn't rent to a friend/family; loaning a boat to someone you know is situational.
Here's a work-around: let's say you have a boat you seldom use and a friend wants to use it for an extended time--like a summer. You sell him the boat with an agreement that you will buy it back for some lesser amount and if it's in as good a condition. You could also finance the sale with a lien on the title but that's more complicated and increases the risk.
A friend did that with a car: his broke down 6 hours from home on the first day of a 10 day family car trip. So he left his with a dealer/mechanic to get a new engine, bought a used one from him (with a large family he needed a Suburban), sold it back to the mechanic on his way home and picked up his repaired vehicle. win win.
My wife and I have talked about renting a larger boat someday for a trip down the intercoastal but other than boat clubs it's hard to charter one around here (sailboats aren't so hard), so if we did it, I'd go for the sale/buy back, or just buy it and sell it open market on return.
None of that applies to the small boat/half day situation of course. But if someone asked you about renting, propose that to put it all in perspective for him.
