When someone is blowing you in a pool and you are walking backwards "towing" them around the shallow end with your knob while making motorboat noises. A variation would be the steamboat, this would be done in a hot tub instead.
I am banned from the public swimming pool for life after doing the tow boat in front of all of those families with that lifeguard last month.

A boat tow is when a man tightly grasps a woman's labia while in a body of water (bath tub, pool,etc) and pulls upon it until the woman howls like the horn on a boat.

The Tow_Boat Method refers to when someone uses their hand to pull a stuck shit out of their constricted asshole.
