Disclosed herein are Melloship personal watercraft, optionally motorized, which are designed to be very comfortable and promote personal relaxation, and even allow one to doze off and nap while maintaining personal safety.

An assembly for a watercraft according to an example of the present disclosure includes, among other things, a flotation device defining an elongated slot extending between opposed ends of the flotation device, and an elongated mount that has first and second flanges extending outwardly from a bracket body. The first flange is configured to be mechanically attached to a frame, and the second flange is slideably received in the elongated slot to secure the flotation device. A method of assembly for a watercraft is also disclosed.

A pontoon boat includes port and starboard pontoons and cross members connecting the pontoons. A shock absorber may be installed at each point of connection of the pontoons to the cross members. A cross member may be embodied as a double-webbed beam having first and second parallel flanges and first and second webs disposed between and connected to the flanges. Each pontoon may include a two-stage lifting strake having a first surface and a second surface inclined from the first surface.

An inflatable water-based motorised device docking station is described. The inflatable water-based motorised device docking station includes an inflatable tube configurable to form an open ended area to receive a water-based motorised device; a floor area coupled to a portion of the inflatable tube; and a ballast bag with dump attached to the floor area and configured to stabilise the inflatable water-based motorised device docking station.

An expansion deck system for vessels includes an elongated deck body that is pivotally secured to a vessel by a plurality of hinges. The deck body transitions between a folded position that does not affect the overall width of the vessel, and an expanded position that extends outward from the side of the vessel. A plurality of triangular-shaped braces is removably secured to the bottom surface of the deck body. The braces including a first section that extends along an entire width of the deck body and a second section that engages a pontoon of the vessel. An electromechanical bracing unit is positioned along the bottom surface of the vessel and includes a linear actuator that moves an elongated rod between an extended and retracted position, and A power lifting unit transitions the deck body between the folded and extended positions.

An alignment guide for a pontoon boat lift that includes a pair of laterally spaced rails, where the spacing corresponds to the spacing between the pontoon floats. The rails are attached to the boat lift by adjustable brackets, so they are positioned at an elevation above the waterline of the pontoon floats, and below the deck that is supported by the floats. A stop bar is positioned at an elevation above the boat motor and extends between rail extensions that are directed downwardly and rearwardly from the spaced rails. The alignment guide functions to provide support under the deck of the pontoon boat, to limit movement of the craft from port and starboard, and to stop the craft when it has advanced to the full forward position to keep it properly positioned bow to stern.

A pontoon boat includes at least two pontoon tubes, a platform supported on the at least two pontoon tubes, and an occupancy compartment capable of containing at least one occupant, the occupancy compartment having a length, a width, an upper portion extending vertically above the platform that includes a ceiling, and a lower portion extending vertically below the platform and into one of the at least two pontoon tubes, the lower portion including a floor surface for supporting the occupant. An entrance to the occupancy compartment is provided in the upper portion that permits the occupant to enter and exit the occupancy compartment.

A structure for stabilizing a barrel on a pontoon vessel includes a deck structure. First And second hull frame members are affixed to the deck structure and extend therealong. In spaced relationship to each other. A first and second conduit extends along a respective hull frame member; the first conduit being spaced from the second conduit by a distance to receive a portion of a barrel therebetween and each conduit contacting the barrel above a barrel central line. A strap having a first end anchored near the first conduit, and tracing a path from the anchor beneath, and in contact with, the barrel disposed between the first conduit in the second conduit, along the second conduit, and returning to the first conduit by tracing a path from the second conduit to the first conduit beneath and in contact with the barrel. The strap having a second end anchored near the first conduit.

A lower deck for a watercraft is attached to and supported by an amidships hull, and an actuator slides the lower deck and amidships hull between a stowed position and an extended position on rails that are secured to the underside frame of the upper deck that is supported by abeam hulls. When fully extended, the lower deck remains attached to the watercraft while a portion of the lower deck's aft section remains beneath the upper deck. A hold within the amidships hull can store accessories used with the watercraft, such as live wells, tables, seats, a foldable slide and ladder assembly, and other items which can be accessed and deployed when the lower deck is extended. The holds are covered by panels which may be individual separable panels, a foldable set of connected panels, or laterally expandable panels. The lower deck can have foldable handrails and recessed cup holders.

Embodiments include a retrofit pontoon system including a pontoon, the pontoon having a pontoon body defining a first cavity, a retrofit assembly, the retrofit assembly including a tube, wherein the tube is sized to pass through a first aperture formed in the pontoon body and a selectively fillable container, where the tube is operably coupled with the selectively fillable container, and a pump, the pump being coupled with the tube such that operation of the pump selectively fills and drains water from the selectively fillable container, where filling the selectively fillable container lowers the profile of the pontoon in the water and emptying the selectively fillable container raises the profile of the pontoon in the water.
