A manual and submersible auxiliary swim platform for a vessel having a main aft platform, the main aft platform having a recessed area for receiving the auxiliary swim platform. A pair of bracket assemblies secure the auxiliary platform to the main aft platform, and both bracket assemblies have a first bracket member, a second bracket member, and a bushing. The bushing is interposed and secured to the first and second bracket members at a common end. The bracket members and bushing have limiter surfaces which limit rotational and pivotal movement of the bracket assemblies in conjunction with external edges, a pin and interface designs of the bracket assemblies.

The present disclosure relates to a rolling reduction boat, and more particularly, to a rolling reduction boat having a structure that allows a rolling reduction tube, which is formed to surround a boat main body, to be filled with water. The present disclosure has the following advantageous effects. That is, according to the present disclosure, by filling a rolling reduction tube, which surrounds a boat main body, with water, there are advantages that the overall weight of the boat is increased, and the center of mass is moved downward and distributed, thus making it easy to get on the boat even in water, and the degree to which the boat tilts or rolls due to external factors such as a strong wind, a wave, and a change in the position of a passenger is reduced and a restoring force of the boat is increased, thus making it possible to more safely sail the boat.

A swim platform is built into a side of a boat, either the port or starboard side. The swim platform is raised and lowered by a mechanism that fits within the side wall of the boat beneath the gunnel. The swim platform is raised when the boat is underway to prevent water intrusion, provide safety, and reduce drag; while the swim platform is lowered, for example, when the boat is anchored for enjoyment of the boaters using the boat.

A bulwark terrace with integrated door is provided; the bulwark terrace may be a portion of a bulwark on a ship or yacht that is hinged so as to be able to fold outwards and downwards and be flush with the deck after doing so, thereby extending the deck surface. The bulwark terrace may also include a door that may open independently of the bulwark terrace to allow boarding of the yacht or ship through the bulwark without deploying the bulwark terrace.

A boat comprises a deck supported by one or more deck floats, and a paddle wheel cockpit comprising a seat proximal to a pedal-driven paddle wheel adapted to engage water and propel the boat; wherein the deck and the paddle wheel cockpit are joined by at least one cockpit hinge that allows the paddle wheel cockpit to fold over the deck, in some embodiments.

A boat with a deck has a sidewall or railing at the periphery of the deck, a door opening in the sidewall with a hinged door, and a pocket ladder assembly adjacent the door opening. The pocket ladder assembly including a stowing enclosure and an access port on one side of the stowing enclosure facing the door opening. A collapsible ladder when in an upright compacted stowed configuration is receivable and stowable in the stowing enclosure. The ladder in the upright stowing configuration is movable laterally out of the stowing enclosure into a door opening seating position when the door is in an open position. The collapsible ladder then rotatable from the upright stowing configuration to an intermediate configuration. The ladder then further convertible from the intermediate configuration to a fully deployed configuration, where the ladder extends outwardly and downwardly from the boat deck.

A platform assembly for a boat has a box assembly that can be mounted in a hull of a boat. A platform assembly is received in the box assembly in a stowed position, but can be actuated to extend to a deployed position projecting from the hull. The platform may include ladder and/or stairs to facilitate entry into the boat, particularly from the water. In some versions, a fold-down railing can be used together with the platform.

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 dive door and ladder assembly includes a door positioned on the side of a boat, preferably in a rearward or aft position. The dive door is attached to a horizontally oriented hinge on a bottom portion thereof, and opens by pivoting inwardly and downwardly (vertically). When the door is in an open position, the underside of the door is generally in a horizontal plane with the upper surface of the doorway, forming a platform for divers and snorkelers to stand on. The upper surface of the doorway further includes a small hatch that may be opened to reveal a compartment therebelow. A collapsible ladder may be positioned within the compartment, in a collapsed state, and may be pulled upwardly from the compartment and folded over the side of the boat, through the doorway and extended into the water.

A marine ladder includes a base and a stair assembly connected to the base. The stair assembly includes four telescoping assemblies, each having an outermost member and one or more telescoping members telescopingly extendable therefrom. A step is connected between the respective outermost members of the four telescoping assemblies. Further steps are connected between respective telescoping members of the four telescoping assemblies.
