Abstract
An apparatus for attaching a pad eye to an underwater ship includes explosives connected to the wings of the pad eye to explosively weld it to the hull of the ship. A water-tight housing holds the pad eye and allows gas to be introduced to drive away all water. Magnets hold the housing to the hull before detonation, a window in the top of the housing allows the diver to observe the entrance of the gas.
