A navigation aid light-signaling device includes a main body inserted in an upper extremity of a dolphin. The light-signaling device includes: fasteners for the attachment of said light-signaling device to the upper extremity of a small dolphin; at least one light source generating a directional and fixed light beam, said light beam being directed toward a second light-signaling device located at a given distance from the light-signaling device on a second dolphin, and a power supply supplying said light-signaling device.

A system for a marine vessel includes a peripheral device having an actuator configured to move part of the peripheral device between a retracted position and an extended position. A first serial bus is configured to connect the peripheral device to other peripheral devices. A controller is operatively connected to the actuator and is in signal communication with the first serial bus. A sensor is coupled to the controller via a second serial bus. The controller is configured to activate the actuator to move the part of the peripheral device from the extended position to the retracted position and from the retracted position to the extended position in response to information from the sensor.

The present disclosure provides a flotation device for ensuring that a container held within the device floats upright in water. The device is a ring with an opening to receive and securely accommodate a container. The ring is comprised of an elastic material to accommodate a variety of sizes of beverage containers and containing a plurality of buoyant inserts such that the ring forms a regular polygon shape. The ring further comprises spacers in between the buoyant inserts for ensuring that the buoyant inserts maintain approximately equidistant spacing, and the floatation device holds its regular polygon shape.

A self-propelled hydrofoil surfboard includes a surfboard having a mast mounted to the lower surface of the surfboard, a selectively controllable thruster mounted at a lower end of the mast, a controller and a battery to supply power to the controller and thruster, the controller cooperating with a remote controller adapted to give control inputs to the controller and to be carried when in use by a rider, navigation lights mounted around at least a portion of the circumferential edge of the surfboard, and wherein the mast may have an adjustable length.

A fin for a water sports board capable of receiving one or more insert accessories is provided. The insert accessories may operate to add a functionality to the fin, and to any board the fin is attached to. Typically, the fin disclosed may be used with a surfboard, paddleboard, or similar water sports board.

The present application is directed to an apparatus that includes a hollow cylindrical threaded channel providing a circular light housing on one end and a pair of conduits passing through the other end, and a threaded nut disposed on the hollow cylindrical threaded channel with one or more elongated arms extending outward and upward from a base of the threaded nut.

A pole light and base system that includes a pole light base configured to be secured to a gunwale of a watercraft. In practice, the pole light base might include a pole light tube and a female Universal Serial Bus connector. The pole light tube may have electrical contacts configured to engage respective electrical contacting portions of an all around light pole if an all around light pole is inserted into the pole light tube. In some cases, the system might include the all around light pole and light. The electrical contacts of the tube might include a positive contact electrically coupled to a first wire and a negative contact electrically coupled to a second wire. The first and second wire may be designed to connect directly to a 12 Volt watercraft battery. They may also connect to a boat fuse box that is connected to a battery. Similarly, the female USB connector can be electrically connected to a printed circuit board that includes transforming components capable of transforming 12 Volt power from a watercraft battery into a lower voltage, such as 5 volt, that is made available via the female USB-A connector.
