A molgogger is a mechanism fixed to a minesweeper ship to tow a paravane or underwater glider to detect and destroy naval mines. Usually constructed of wood and non-ferrous metal to reduce the magnetic signature, the molgogger would have supported a towing cable which when it snagged the cable anchoring a mine then the anchoring cable would be cut, allowing the mine to float to the surface where it could be destroyed by gunfire. If the anchor cable would not part, the mine and the paravane would be brought together and the mine would explode harmlessly against the paravane.
