last winter buddy with somewhat short keel found that the ramp is not endless but stops... Trailer tires dropped off the end of the submerged ramp ... required a diver to get them back on the ramp. so OK the diver was part of the fire department, and had a fire truck and two assistants with him. With the fire truck automatically came a police car, and then we also had a tow truck ... duh... [what you see is the front mast carrier which was the only thing above water.]
