A retractable entry/exit system for a boat that mounts below a swim platform or other similar boat structure. The system has a main frame, a linkage, a number of step assemblies and a single actuator. The actuator is configured to move the linkage to selectively extend or retract the step assemblies. When retracted, the system is folded into a compact arrangement under the mounting structure. When extended, the step assemblies extend beyond the mounting structure, where they can be used to conveniently enter and exit the boat or as a place to rest, lounge, sit or otherwise enjoy the water. The linkage may include a bell crank assembly with integral linkage arms, as well as a pair of supplemental linkage arms. The linkage arms may be disposed toward opposite sides of the system and may be operatively coupled to step brackets that support opposite ends of each step assembly.

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.

A collapsible marine ladder has a stowed configuration and a deployed configuration. The collapsible marine ladder has a first rail, a second rail, and rungs. Each rung has a rung length spanning between the first rail and the second rail. A rung attachment is attached to each of the plurality of rungs, wherein the rung attachment comprises a rung attachment body, a recess along a bottom section of the rung attachment body for receiving the rung, and a top surface of the rung attachment body. A first section of the top surface is above the rung when the rung attachment is attached to the rung and the collapsible marine ladder is in the deployed configuration. A second section is cojoined with a front side of the first section and wherein the second section is downwardly angled such that an angle is formed between the first section and the second section.

A boarding apparatus for use on a flotation device, in accordance with various embodiments is disclosed herein. The boarding apparatus comprises a stirrup ladder. The boarding apparatus may be integral to a lifeline assembly of the flotation device. The boarding apparatus may be removably coupled to a loop patch of the flotation device. The boarding apparatus may release from the loop patch and become a boarding configuration for the flotation device.

The present disclosure describes recreational watercraft that provide a ballast system and an open platform passenger deck. An example is an aluminum hull including a ballast system to regulate displacement by the recreational watercraft and an open platform passenger deck as an integral upper surface to the aluminum hull. Multiple sides, continuous from the aluminum hull, include a stern side, a bow side, a port side, and a starboard side that surround a perimeter of the open platform passenger deck. An inboard power plant is located within a stern portion of the aluminum hull to propel the recreational watercraft.

A movable platform assembly for a boat includes a support structure configured to be connected to the boat, a platform, and a horizontal translation system connecting the platform to the support structure, the horizontal translation system having a pair of main arms rotatable about respective vertical rotation axes, and a pair of main sliders sliding in a transverse direction along a main guide integral with the platform. Each main arm has a proximal end hinged to the support structure and a distal end hinged to a respective main slider. The platform is translatable between a retracted position and an extended position with respect to the support structure.

A self-contained knotless security device and method for adjustably securing rope-style pilot ladders and debarkation ladders from any rung to ship deck lashing points, the device not relying on additional mechanical fittings or knot-tying skills. The device comprising a section of multi-strand polyester rope comprising an integrated polyolefin core and having a ship end and a ladder end, the ship end comprising a rugged, wear and corrosion-resistant thimble eye or shackle and the ladder end comprising a flexible long soft eye on the other end. The method comprising encircling ladder suspension members with the device and securing the device to the ship deck lashing point. Alternate polyolefin core construction provides tailored performance characteristics.

Attachments for a collapsible marine ladder including a rung attachment for attaching to the ladder rungs. Each rung attachment includes an upper part having a first channel defined along a downward facing side of the upper part. The first channel receives an upward facing side of the rung. A downwardly angled section of the upper part extends below the rung when the upper part is attached to the rung. A pad is received on top of an upward facing side of the upper part and interfaces with a user's foot. A second channel on an upward facing side of a lower part receives a downward facing side of the rung such that the upper part attaches to the lower part. A rail attachment attaches to a rail of the ladder and receives a rail extension for extending the length of the rail. The rail extension has a handgrip.
