A powered water vessel includes a unitary section of the bow that is pivotably rotatable about a horizontal axis thereby permitting a closed-bow configuration and an opened-bow configuration. The closed-bow configuration is generally amenable to regular boat operations, while the opened-bow configuration is generally amenable to loading and unloading passengers, vehicles and/or cargo. A folding ramp assembly is extendable through the open-bowed configuration for loading and unloading, with track extensions providing additional extension distance.

A marine vessel may include a propulsion system and a rechargeable energy storage system inclusive of at least one rechargeable energy source configured to supply power to the propulsion system. The marine vessel may further include a vessel-side inductive charge component in electrical communication with the rechargeable energy storage system, and be configured to inductively couple with a platform-side inductive charge component positioned at a marine-based platform. The platform-side inductive charge component may be electrically coupled to a power generator that generates electrical power. A moveable structure (e.g., gangplank or crane) may be coupled to the marine vessel on which the vessel-side inductive charge component is positioned to enable the moveable structure to be moveably positioned to wirelessly (e.g., inductively) couple the vessel-side inductive charge component with the platform-side charge component that is positioned at the marine-based platform, thereby causing the rechargeable energy storage device to be recharged.

A device, such as a gangway, for transferring personnel and/or goods from a surface vessel to a fixed or floating structure, e.g. an offshore structure, such as a wind turbine, or to another vessel, the device comprising first and second telescoping elements and an intermediate platform for bridging the transition between the first and second telescoping elements, which platform is movable relative to both telescoping elements.

Vessel (60), comprising a transverse bow (62) with an elongated bow fender (10) protruding with respect to the bow (62), which bow fender (10) is designed to be pushed against a stationary object (50), said vessel 60) further comprises at least two engagement arms (20) with telescopic parts (22,24), said engagements arms (20) are mounted in a position above the bow fender (10) and facing each other, and each engagement arm (20) is pivotable against each other for engagement with the stationary object (50) from opposite directions. Each engagement arm (20) comprises a tiltable engagement pad (26) with a contacting surface (26a) creating stabilizing contact between the contacting surfaces (26a) of the engagement pads (26) and at least a part of the stationary object (50), said engagement pads (26) being tiltable about an axis running in same longitudinal direction as the engagement arms (20).

A deck extender for a personal watercraft can include a deck member supported in a cantilevered configuration over an edge of the deck of the personal watercraft. The deck extender can include mounting sleeves fixed to an upper deck of a personal watercraft with mounting tabs of the deck member received within the mounting sleeves. The deck member can include mounting mechanisms having a receptacle and a pivoting cleat mounted above the receptacle configured for mounting accessories to the deck member. The deck member can have recessed channel members for mounting accessories.

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.

A gangway has a proximal gangway element, a distal gangway element, a distal stanchion hinged to the distal gangway element, and a distal stanchion control mechanism for converting sliding movement of the distal gangway element into rotational movement of the distal stanchion. The distal stanchion control mechanism has a spring associated with the distal stanchion and configured to bias the distal stanchion towards a raised terminal position, a return bracket slidably mounted to the distal gangway element, and a cam member rotationally integral with the distal stanchion and configured to engage the return bracket. With the distal gangway element in the retracted terminal position, the return bracket abuts against a distal end of the proximal gangway element and is located in a distal terminal position relative to the distal gangway element. Raising of the distal stanchion is caused by movement of the distal gangway element relative to the return bracket.
