Craft including hull having stern with mobile platform having first work position where it is extracted from water, and second work position where it is immersed in water, device for platform movement having a pantograph, a structure with an articulated quadrilateral connected to the mobile platform, said movement and a unit for actuating movement of this structure, which unit allows moving the platform from the first to second work position and vice versa. The structure with articulated quadrilateral folded back onto hull when platform is in first position, and extended when platform is in second position. The movement device includes a body distinct from hull. The structure with articulated quadrilateral integral with, but mobile relative to body. The body secured on hull stern and having at least one fixed step, at least one second step inside the structure with articulated quadrilateral, which step moveable and foldable back with the structure.

The invention is a multi-sectional floating dock that can be customized into 9 different configurations. This process is accomplished by inserting a tool into a rotation hole on the stationary dock and rotating it, which in turn rotates each of the four rotating dock sections into the desired format. The tool inserts into the rotation hole through various Insertion points and meets with a long row of teeth mounted on the bottom of the stationary dock. The gear and the teeth align so when you rotate the tool, this in-turn rotates each dock section pivoting around the symmetrical radii. Everything that rotates and moves is completely symmetrical in shape, size, and length. The docks will be outfitted with bullet holes for optional accessories that can be locked into place. A motorized version will also be available.

A buoyant structure having a hull, a main deck, an upper cylindrical side section extending downwardly from the main deck, an upper frustoconical side section, a cylindrical neck, a lower ellipsoidal section that extends from the cylindrical neck, an ellipsoidal keel and a fin-shaped appendage secured to a lower and an outer portion of the exterior of the ellipsoid keel. The upper frustoconical side section located below the upper cylindrical side section and maintained to be above a water line for a transport depth and partially below the water line for an operational depth of the buoyant structure.

A watercraft with a hull assembly and a mat storage system coupled to the hull assembly. The hull assembly may have a mat compartment with the mat storage system configured to move the mat between a stored position, in which at least a portion of the mat is positioned in the mat compartment, and a deployed position. The mat compartment may be positioned beneath at least a portion of a floor of the hull assembly. The hull assembly may have a cover positioned adjacent the mat compartment and moveable between a closed position, in which it covers at least a portion of the mat compartment, and an open position. The mat storage system may have a motor that is configured to move the mat to a stored position.

A dual-phase refrigeration system for chilled storage containers (CSC) aboard boats maintains cold temperatures in the CSC by chilling the airspace in the upper portion of the CSC. A cooling liquid is circulated through coils installed on an interior sidewall about an upper margin of the CSC. The cooling liquid chills the air in the upper portion of the CSC which creates a thermodynamic airflow within the CSC which aids in cooling. The temperature of the cooling liquid is maintained by a heat exchange with a Non-Ozone Depleting Hydrofluorocarbon (NODHFC) refrigerant which, in turn, is cooled by a heat exchange with circulating water sourced from the body of water supporting the boat. If ice is added to the CSC, the cooling liquid in the coils reduces the air temperature and optimizes thermodynamic airflow to eliminate the temperature differential across air/ice interface and maintains the quality of the ice.

Devices, assemblies, kits and methods for an accessory for a recreational vehicle are shown and described. An accessory may include a tray, an extension and a cover for the tray. The tray may be a horizontally oriented tray supported by the support and having a set of compartments and a set of recesses. The tray may be mountable between variable positions.

A water vessel includes a deck having an upper surface and a lower surface. First and second hulls are spaced-apart from one another and operably coupled to the lower surface of the deck. At least one of the first and second hulls has an at least partially hollow interior. A storage tank is positioned within the at least partially hollow interior of at least one of the first and second hulls. A tub for holding water is supported by the deck. The tub includes an interior cavity having a capacity and is fluidically coupled to the storage tank. The storage tank has a capacity less than the capacity of the tub. A pump system is configured to direct water between the tub and the storage tank and at least partially fill the capacity of the tub.
