keel-haul

a medeival naval punishment that involves tying a line to each arm of the convicted sailor and pushing him off the bow of the ship under sail. the sailor was ‘hauled’ along the barnacle encrusted ‘keel’ of the vessel aided by the movement of the ship and pulled back aboard at the stern of the ship. it hurt really bad.
“the punishment for stealing rations is keelhauling!”
keelhauling was a form of punishment for sailors at sea. the sailor was tied to a rope looped beneath the vessel, thrown overboard, and then dragged under the keel and up the other side.

keelhauling was generally a death sentence since it could take as long as three minutes, and perhaps longer, to walk the ropes all the way back to the stern. often the ropes caught and dragged on barnacles on the ship’s hull: the barnacles ripped the victim’s clothing and skin to shreds as he was dragged along.
