A system is provided. The system includes a fuel receiving module configured for being installed within a marine vehicle, the fuel receiving module including at least a fuel receptacle. A tank module for storing gaseous fuel is provided. The tank module is in communication with the fuel receiving module. A pressure reduction module is configured for reducing a pressure of the gaseous fuel from the tank module to a pressure suitable for an engine of the marine vehicle. An engine module is in communication with an engine control module for controlling operation of the engine. A helm control module is in communication with the engine module and at least one other module for controlling operation of the system.

A camera mounting system for a vehicle. The camera mounting system comprises a base mount configured to be coupled with an exterior surface of the vehicle. The base mount includes an interior space. The camera mounting system additionally comprises a sub-housing received within the interior space of the base mount. The sub-housing is configured to rotate within the base mount. The camera mounting system additionally comprises a camera configured to be removably mounted to the sub-housing. As such, when the camera is mounted to the sub-housing, the camera is configured to rotate in conjunction with the sub-housing. The camera mounting system additionally comprises at least one damper configured to permit a position of the camera to translate toward the sub-housing in response to an external object impacting the camera. The camera mounting system further comprises at least one attitude sensor configured to sense an orientation of the camera.

A device for connecting the elastic elements and dissipaters of variable type of a mechanical suspension interposed between two vibrating or tilting mechanical systems, the source body and the receiving body, respectively, in order to reduce the forces acting on the receiving body, and/or the displacement thereof, and/or the speed thereof, or combinations of the previous physical magnitudes and/or of any other ones, which are produced on the receiving body due to the motion or forces to which the source is subjected. The device consists of elastic elements, such as metal components or compressed gases, energy dissipating elements, either by means of friction between fluid and solid, and between solid and solid, or by means of suitable electromagnetic couplings the damping ability of which can be automatically varied by a suitable control system according to the operating conditions of the suspension; elements forming the kinematic connection structure between the elastic elements, damping elements, source and receiving bodies, such connections being solid or fluid or electromagnetic connections.

A combination fishing pole holder and cleat has a bezel portion for affixing to a surface. The bezel portion has a first hole for accepting an object and a shaped indentation to accept and fit a cleat portion. The bezel portion has a pair of studs, each having a cavity formed there within. The cleat portion is shaped to fit within the shaped indentation and has a second hole, also for accepting the object. A pair of legs extends from the cleat portion and through respective studs. Each of the legs is terminated by a device/end that is wider than the cavity of the studs. A tubular portion extends from a side of the bezel and is aligned with both the first hole and the second hole for insertion of the object. The cleat portion moves between a retracted position and an extended position.

A fender hook is disclosed that is formed by a base material carrying a gripping material disposed between sections of hook and loop material. By wrapping the base material over upon itself, the gripping material is brought into frictional engagement with a mounting substrate such as a nautical railing and is held in place by the hook and loop material.

The present disclosure belongs to the technical field of power generators, and in particular relates to a marine support column structure with power generation function. The support column structure solves technical problems that existing marine power generators can only generate power with single energy and have few functions and so on. The marine support column structure with power generation function includes a column body. The support column structure of the present disclosure is capable of generating power with sea wind and waves, and is further capable of serving as a guardrail.
