Ramp assembly systems and methods of use are described. According to one aspect, a vessel ramp assembly system includes a ramp assembly configured to assist with ingress and egress of an individual with respect to the vessel, a deployment system configured to move the ramp assembly between a stowed position with respect to the vessel and a deployed position with respect to the vessel, and a positioning system configured to move the ramp assembly to move a first end of the ramp assembly with respect to a deck of the vessel and provide a second end of the ramp assembly at an appropriate position where the individual may use the ramp assembly for the ingress and egress with respect to the vessel.

A floating device for transfer of personnel and material to and from the shore, where the device is divided into sections that are mutually brought together by articulated couplings to form an extended, continuous path for the transfer of said personnel and material, as the sections are set up to be reset between a parked, folded position and an extended, using position. The device is characterized by a first section (10) that comprises mutually separated hull sections (14, 16) that are connected via a deck (12) where the other sections (20, 30) in the device are set up to be parked in under the deck (12) between the hull parts (14, 16) of the first section (10), and also that the device comprises means to securely couple the other sections (20, 30) to the first section (10) up under the deck, as the hull parts can be ballasted to be able to raise and lower the first section (10) with regard to the other sections (20, 30).

A ladder system for a boat having gunwale tubing comprises a ladder including two side rails and at least one rung transversely disposed across the side rails and a platform having a curved recess and platform surface. The top portion of the ladder is pivotably attached to the side of the platform and extends downward therefrom. The platform is disposed on the gunwale tubing of the boat such that the curved recess of the platform receives and engages the tubing. A stanchion extends laterally from the ladder and includes two support each extending from a corresponding side rail of the ladder. A stanchion pad is disposed at an end of said stanchion disposed between the two stanchion supports, and engages the hull of the boat to prevent twisting of the ladder when it is deployed. The ladder system prevents deformation of the gunwale tubing while providing enhanced stability.

A boat ramp designed to collapse so the amphibious vehicle may be towed at highway speeds. The ramp fabricated of a central isosceles triangle hinged to the vehicle at its base flanks a pair of right triangles hinged along their hypotenuses such that the ramp can be folded over the vehicle during travel. The hinged portion is reinforced with removable steel channel during use.

Disclosed is a boarding apparatus for boarding animals onto a boat or other above-water surface, and methods of using the apparatus. The apparatus has a boarding step assembly, a mounting assembly attached to the boarding step assembly for connecting the step assembly to a boat hull gunwale or transom lip, and a strut assembly for supporting the engagement of the boarding step assembly to the boat hull.

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.

Aspects of the disclosure include apparatus for and methods of facilitating transfer of objects using a crane. Disclosed apparatuses include a target tracking device mounted on or near a crane at a first location, and a target located near a landing location for the object. The target tracking device and the target facilitate real time determination of relative motion between the two locations. Methods of using the same are also disclosed.
