Abstract: The powered retractable ship ladder replaces the current technology of manually-lowered ship ladders. The powered ladder includes powered extension and retraction, with the added capability of being able to lift a user during ladder retraction. The ladder is formed from a collection of links. The links only permit the ladder to bend in one direction, thus keeping the extended ladder against the side of the ship, rather than swinging toward and away from the ship.

Abstract: A high speed, reduced clearance lift has a lift platform that is raised and lowered by operation of a telescoping hydraulic ram that has at least three telescoping sections, such that, the retracted height of the telescoping hydraulic ram is minimized while the deployed height of the telescoping hydraulic ram is such that the lift platform is lifted the height needed to, for example, lift a device out of the hull of a watercraft. To better stabilize the lift platform both in the retracted and deployed positions, locks, preferably in the form of actuated locking pins, interface with receivers mounted in a frame in which the lift platform travels. In such, when the locking pins are extended into the receivers, the lift platform and any payload resting on the lift platform are held steady without the need for hydraulic pressure.

Abstract: A swim platform lift mechanism is disclosed, the mechanism mounted between the transom of a boat and a bottom surface of a swim platform. The lift mechanism provides a powered lifting/lowering of the swim platform from a retracted position that is level with the deck of the boat to a deployed position in which the swim platform is below the surface of the water surrounding the boat and from the retracted position to an up-and-over position in which the swim platform and its contents are positioned above and forward of the rear edge of the deck. When in the retracted position, an adjustable stop interfaced to the swim platform abuts rest areas on lower arms of the lift mechanism, thereby providing structural support to the swim platform.

The up-and-over position provides for an improved center of gravity when transporting a dingy on the swim platform.
