A crane for ships and having a boom pivotally mounted for vertical movement on a base, telescopic hydraulic jack means connected to the boom to support the outer end thereof in a desired position, a pulley carried by the boom near the outer end thereof and means for shifting the pulley towards and away from the base, a cable threaded over the pulley and winch means for reeling in and paying out this cable, and a control system including accumulator means connected to the jack means for maintaining the boom outer end substantially in the position thereof regardless of ship motion under wave action when the cable is supporting a load in the water.

Heave compensating cranes

A method of launching and recovering self-propelled submersibles by using a drogue below the surface of the water where comparatively stable conditions exist. A probe on the submersible is unlatched from or latched to the drogue during relative movement therebetween when it is desired to release or recover the submersible. The apparatus includes a suitable drogue, a probe connected to the submersible, and releasable latching device in the drogue and on the probe.
