The reality of course was that the whole escapade was planned by a couple of 20 years olds who knew nothing. The only reason we didn't sink both boats was just dumb luck absolutely nothing more.
Why don't you just call your local BoatUS or TowBoat guy tell them you are a member and be up front and say your boat is in place x and needs repair
work done in place y and want a tow.
It is a shot. And if you pull it off even with some cost at least you have no risk. They know how to tow safely. If you don't want to fib about being a member to just ask the question just go down to the dock in the evening and chat up some friendly looking captains and get them to make the call for you. The phone call doesn't cost them anything.
I have boatUs and they have been remarkably helpful. You don't want to take advantage of them but if you ask nicely?
