A retractable hammock support system includes a tubular housing and a first plurality of wheels. The first plurality of wheels are secured to the housing. The system includes a tubular member having a first portion disposed within the housing and a second portion disposed outside the housing. The member is slidable into or out from the housing. In a retracted position, the second portion has a first length. In an extended position, the second portion has a second length. The first length is shorter than the second length. The system includes a handle disposed on the member. The handle is disposed on the second portion of the member. The first plurality of wheels are disposed within an interior space of the member. The first plurality of wheels are configured to contact a first internal surface of the member.

A system includes a housing and a swim up bar configured to be mounted on a boat. The swim up bar is movable into or out from the housing. In a deployed position, the swim up bar is extended from a bow of the boat. In a storage position, the swim up bar is contained within the housing.

An articulating top having a frame, a cover attached to the frame and a mounting bracket to attach the frame to a vehicle can be moved between a deployed position to provide shelter to an area below the top and a stowed position. The frame having main and secondary frame members in addition to one or more struts between a frame member and the vehicle to provide additional support to the frame such that the top can be used while the vehicle is in motion or in windy conditions. The top may also use one or more braces.

A seating assembly for a watercraft is provided. The watercraft has a deck including deck attachment features provided on an upper surface of the deck. The seating assembly includes: a padded mat for seating a user, the padded mat being configured to abut the upper surface of the deck, the padded mat having a mat attachment feature for selectively connecting the padded mat to the deck by engaging the mat attachment feature with one of the deck attachment features; and a backrest for supporting a back of the user, the backrest having a backrest attachment feature for selectively connecting the backrest to the deck by engaging the backrest attachment feature to an other one of the deck attachment features. The padded mat and the backrest are usable together to allow the user to sit on the padded mat and be supported by the backrest.

The invention relates to a watercraft, particularly a kayak having a battery compartment and motor mount for mounting a motor thereto. The kayak can be propelled either by a motor mounted to the motor mount or by manual paddling by a user of the kayak. The kayak may additionally have a seat mounted onto a track to allow the user to adjust their position as needed in the kayak. The kayak is extra wide to provide stability, while chamfered side walls allow the user to paddle with comfort regardless of the extra width. The kayak may optionally have wheels mounted thereon to facilitate handling and transport by the user.

Embodiments of the present apparatus and method feature a permanently fixed canted keel. The apparatus and method feature tacking maneuvers which shift the sail element and reverse the direction of the hull form.

A light display system and device for use in a body of water or other liquid is described. The light display device may be controlled remotely via a control hub and/or control panel, or controlled by internally preprogrammed commands. A plurality of light display devices may be controlled in selected, choreographed sequences to provide various unique visual displays including, for example, geometrical patterns and/or naturalistic patterns giving the impression of organic phenomena such as swarming fireflies, bioluminescent creatures and the like.

A marine helm seat includes a seat base positionable within a marine vessel. The marine helm seat also includes a seat back extending from the seat base in an upward direction from a longitudinal axis of the seat base. Further, the marine helm seat includes an actuation mechanism that reclines the seat back in response to a reclining force acting on the seat back. The actuation mechanism is also able to lock the seat back in a reclined position. Additionally, the actuation mechanism is positioned on an underside of the seat base.

A system for repelling sharks is disclosed. Magnets are connected to a rod along its length. If necessary, the rod may be extended. Additionally, one or more flotation devices may be connected to the rod to manipulate or adjust the buoyancy of the system, depending on the user's objective(s). The rod is connected to a fishing line once a fish is hooked and is in close proximity to the boat or other structure from which the fisherman is fishing. The weight of the rod and magnets cause the rod to slide down to the end of the fishing line, where the rod will come in contact with the hooked mouth of the fish. As the fish struggles during the fight, the rod creates a protective magnetic field around the fish to deter sharks from engaging the fish.

A multi-functional aquatic vehicle comprises a main body. The main body comprises: a propulsion system, comprising at least one propeller for changing a motion attitude of the main body; a camera system, comprising at least one camera; a communication system, comprising a signal receiving module for receiving an external signal detected by the aquatic vehicle and a signal transmitting module for transmitting a signal to an external control system; and a control system, for controlling an operating state of the propulsion system, adjusting a capturing angle of the camera system and controlling internal and external communication of the communication system. A towing hook device comprises: a driving system, a connecting mechanism and a towing hook mechanism. The driving system drives the connecting mechanism to rotate such that the towing hook mechanism turns over or rotates to release a load.
