View with the mooring attached to the ships trawl wire. The quick release is attached to the wire; the three legs of the release rigging go thru the lifting eyelets and back up to the quick release via a sash which captures all of the three point attachments.
Side view of the mooring rigged and ready to put over the side. Note the yellow polypro line - this is the release line for a safety pin which keeps the quick release from dropping the load when it hits the sea surface. Once the package is approx 1m below sea-surface, the safety pin is pulled and the gear can be lowered to the deployment site. When the mooring hits bottom, the fulcrum of the quick-release pivots down, releasing the 3 point rigging from its grasp. The trawl wire is then brought back up to the surface which pulls the rigging back thru and free of the lifting eyes.

Mooring rigged and ready to go over the side. Tag lines are used to control the moorings side to side movement as the gear is put over the stern.
