ABSTRACT:
Equipment for the raising, sunken vessels, specifically small to medium sized ships which are submerged in depths to which human descent for purposes of rigging retrieval gear to the ship is impractical or unsafe. The equipment can be employed remotely using video equipment for aligning the required underwater assemblies. The equipment involve lifting slings which are levered underneath the hull and then used to mechanically raise the vessel to the surface. It is particularly applicable to vessels which are resting on soft sand or clay ocean, sea, or lake bottoms, where interferences with the equipment as it is deployed underneath the vessel are a minimum.
