Heard of a "Story" once that a new joy boat owner lauched his cabin cruiser out of Ky Dam marina and then proceeded to run out into the lake for a while. New boat owner, first boat ever owned, can't get on plane and does not understand it. Comes back into the marina and ties up to the dock, goes inside and asks around to which finally a person comes out to take a look and sees the trailer still attached to the boat. The boat owner was serious in the fact that he did not know that he had to take the boat off the trailer. The way it was told to me, is the boat owner intentionally unhooked the hitch. I guess it takes all types.
