Marine lift apparatus for raising and lowering vessels, platforms, and cargo are disclosed. A lift apparatus comprises a multi-component structure capable of movement, at least one flexible member, and at least one piston device. In some aspects, marine lift apparatus facilitates the level raising, lowering, and storing of vessels, platforms, and cargo. Lift apparatus mountable onto multi-hull vessels, such as catamarans, configured for lifting a combination swim and dinghy platform are also disclosed.

A vehicle system may include a mother ship and an unmanned water vehicle that can be received on the mother ship. To recover the unmanned water vehicle, a floating body connected to the mother ship via a line can be lowered into water. A catch device for catching the line may be positioned on the unmanned water vehicle. The floating body may transmit location signals that can be received and used by the unmanned water vehicle to navigate towards the floating body. The unmanned water vehicle may be configured to circle the floating body, and the catch device of the unmanned water vehicle may then catch the line to create a connection between the mother ship and the unmanned water vehicle.”

Disclosed is a floating structure for an autonomous watercraft with a keel deployed and recovered on a vessel. The longitudinally elongate structure includes a floating port-side and starboard lateral edges and a submersible bottom submerged when the structure is in the water, the lateral edges and the bottom defining an interior space at least partly submerged when the floating structure is in the water, the lateral edges defining a prow at the front and, at the rear, an opening towards the rear of the floating structure, which opening is downwardly limited by the submersible bottom with at least one longitudinally elongate slot open towards the rear for the passage of the keel, and the floating structure is configured in order that at least the front portion of the autonomous watercraft including the keel can engage by floating inside the interior space, with the keel engaging in the slot.

The invention relates to an apparatus for launch and recovery a submersible vessel from and to an off-shore site. The apparatus comprises an actively operated gimbal coupled between said first end of the launch/recovery cable and the submersible vessel, when the submersible vessel is suspended by the launch/recovery cable. Both the displacement unit and the winch areoperated by electrical motors during displacement of the displacement unit and during winding of the launch/recovery cable. Electrical power for the electrical motors is provided by batteries of the apparatus.
