Overboard!

An early middle aged man starts out on a relaxing overnight sail for the weekend; intentionally alone on his sailboat to enjoy some solitude. As he is motoring down channel, on his way out of the harbor, he is passed by a pontoon boat, fully loaded with college kids. A girl on the party boat sticks her head up and makes eye contact with him, moments later she jumps overboard and swims over towards him. He brings her aboard and thus starts an unexpected relationship between them which includes a rescue, an education and a romance.
