A water vessel boarding ladder device and method of manufacture are described herein. The boarding ladder device may include one or more of a ladder portion, a handle portion, a coupling portion, and/or other components. The coupling portion may be configured to provide a variable rotational relationship between the handle portion and the ladder portion during simultaneous rotation of the handle portion and the ladder portion.

Boats can include a swim platform with an integrated system of steps that can be selectively deployed and retracted. Such platforms can be attached to a transom of a boat or can be fabricated as an extended portion of the boat's hull. In another embodiment, deployable steps can be integrated with a boat's hull as a side-entry door. In order to reconfigure the step system into a deployed configuration, a linkage is actuated that causes the step system to unfold, forming steps (or a seating configuration) at least partially below the water line. Since the steps can be deployed below the water line, a swimmer can more easily get on board the boat.

A deployable marine system for anchoring a vessel in a body of water and to enable a user to ingress into the vessel from the body of water or egress out of the vessel and into the body of water, the deployable marine system includes an anchor-ladder device and a deployment device. The anchor-ladder device includes a first member and one or more steps, the first member including a first end and a second end. The second end is opposite the first end and is associated with an anchoring component that may anchor the vessel. One or more steps may be attached to the first member. The deployment device may be attached to the vessel, connected to the first member in proximity to the first end, and may deploy the anchor-ladder device into, or retract the anchor-ladder device from, the body of water.

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.

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 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.

The present disclosure includes recreational watercraft including a drop down boarding point. One example includes a hull, an open platform passenger deck, and a plurality of sides, continuous from the hull. The watercraft includes a panel drop down boarding point, hingedly attached horizontally to the hull, for ingress and egress of persons to the watercraft. The panel drop down boarding point includes a first surface interior to the watercraft when the panel drop down boarding point is closed, a second surface, opposite to the first surface and exterior to the watercraft when the panel drop down boarding point is closed, and an aperture formed between the first surface and the second surface and having an opening in an end surface of the panel drop down boarding point. The aperture is sized and shaped to house a retractable ladder and for the ladder to extend out through the opening.

The objective of the present invention is to provide an accommodation ladder fixing device, which more firmly and safely fixes, to an exterior wall of a ship, an accommodation ladder temporally provided so as to allow pilots to safely board and disembark the ship. That is, the present invention comprises: a housing (10), which has a fixing plate (13) formed at the rear end thereof to be mounted on the accommodation ladder (100), has a fixing box (11), of which the front side is opened, formed on the fixing plate (13), and has hinge shafts (15) formed at both sides of a through-hole (14) of the fixing box (11); an attachment/detachment means (20), which has a movable block (21) insertively provided so as to be movable forward and rearward to/from the fixing box (11), and a magnetic member (22) attached/detached to/from the exterior wall of a hull (200) and provided at the front end of the movable block.

A restraining device, such as a bolt, pin, or latch, removably secures a connector sleeve to a U-bolt, such as a tow-rope-eyelet on the bow of a boat hull. The connector sleeve is machined with an internal cavity having surfaces and dimension that correspond to outer surfaces of the U-bolt. The sleeve contains holes through which the restraining device passes after the sleeve has been slid over the U-bolt such that the restraining device, while installed, prevents the sleeve from sliding back off of the U-bolt. The sleeve also includes accessory mount holes to receive restraining devices that attach an accessory, such as a ladder, to the sleeve and thus to the boat via the sleeve that has been secured thereto. The sleeve may provide for set screws to snug the sleeve to the U-bolt if clearance exists between surfaces of the cavity and the U-bolt.

The invention relates to a platform arrangement (110) mounted to a stern portion of a marine vessel (100). The platform arrangement comprises at least one first platform section (111) with a first transverse pivot joint (113) mounted adjacent a transom (105); at least one propulsion unit (101) mounted to a lower surface of the first platform section (111), wherein the at least one propulsion unit (101) and its first platform section (111) are tiltable between a drive position and an upwards tilted position. A second platform section (112) is located in front of the at least one first platform section (111), which second platform section (112) has a second transverse pivot joint (114) mounted adjoining the first transverse pivot joint (113) of a corresponding first platform section (111). The first and second platform sections (112) are foldable relative to each other about their respective first and second pivot joints (113; 114). The invention further relates to a vessel comprising the platform arrangement.
