This disclosure provides wave-powered vessels equipped for fish stock management. The vessels have observational sensors for monitoring fish, a positional sensor to determine the geographical location of the vessel, and a transmitter for sending data to a central control unit. The observational sensors may be deployed on a tow body pulled behind the vessel, or the tow body may relay information from sensors located on a separate unit on the bottom or at a defined depth. The control unit communicates with each of the monitor vessels to direct navigation and obtain data from the sensors. Substance distribution vessels in the fleet are equipped to distribute fish food in target area for the purpose of fish farming.

A mooring device includes a canister, a spool having two side walls with teeth around their perimeters, a mooring cable wrapped around the spool, a lid having a first piece and a second piece, and two pairs of stops extending from the bottom surface of the lid. The two pairs of stops engage the notches of the two side walls of the spool when the first piece of the lid rests in the closed position. The stops disengage from the notches when the first piece of the lid is open. A thumbpad allows a user to move the stops from a lock position to an unlocked position without opening the lid. The device extends and retracts the cable to accommodate tidal and other water action.

A motorized watercraft is a vehicle that is used to transport a user across the water. The motorized watercraft includes a floating board, a control unit, at least one electrically accessible system, a power source, and at least one conduit stringer. The floating board allows a user to float above the water. The at least one electrically accessible system may include a propulsion system, lights, or other features. The control unit is mounted to the deck of the floating board and is used to regulate the speed of the propulsion system and may be used to control lights which are mounted into the floating board. The power source is used to provide the energy needed for running the propulsion system and the lights. The conduit stringer runs through the floating board, strengthening the floating board and providing a channel through which wiring may run.

The present invention provides a solar panel float in which an increase in the number of components is prevented and which is easy to assemble. A float for mounting a solar panel is provided with: an annular float portion; a first support portion that supports an edge on one side of the solar panel; and a second support portion that supports an edge on the other side of the solar panel. The first support portion includes a first support plate portion rising from a wall surface on one side of an inner periphery of the annular float portion. The first support plate portion is formed of a cut-and-raised piece that has been cut and raised, from a flat plate portion integrally formed so as to close the inner periphery during molding of the annular float portion, using a lower-side portion of the flat plate portion as a bending-fulcrum point.

A system for collection of rainwater in the open ocean may include: (a) one or more ocean-going vessels, wherein each ocean-going vessel is configured for collection and storage of rainwater, wherein each ocean-going vessel is configured to drift with surface ocean currents in order to navigate to one or more delivery locations, wherein each delivery location is on or near to a land mass; and (b) one or more delivery stations located at the one or more delivery locations, wherein each delivery station is configured to receive stored rainwater from one or more of the ocean-going vessels.

An electrically-propelled marine vehicle and method of making same, including providing a hull of the marine vehicle and mounting a submersible electric thruster to the hull. The thruster includes a stator assembly and a rotor assembly. The rotor assembly forms an internal cavity with a plurality of magnets arranged radially outwardly of the internal cavity. The stator assembly includes electrical windings that are disposed within the internal cavity of the rotor assembly. The thruster is configured to allow the internal cavity to be flooded with water when the thruster is submerged, and the electrical windings are covered by a protective barrier that prevents the flooded water from contacting the windings. The thruster of the marine vehicle is thus water cooled, and the electromotive forces provided by the windings generate sufficient thrust to propel the marine vehicle through the water.

Provided are an offshore floating light energy storage integrated charging station system and an operation control method thereof. The system includes a triangular floating floater structure, a control unit mounted on the floating floater structure, an energy storage tank arranged on the floating floater structure, an energy storage unit mounted in the energy storage tank, and a photovoltaic electricity generation unit paved on the energy storage tank. A battery pack in the energy storage tank on each triangular floater is one energy storage unit. The energy storage unit can independently supply electricity or charge the vessels when the photovoltaic electricity generation unit does not generate electricity and the state of charge of the energy storage unit is sufficient. The energy storage unit are controlled to switch between four control modes according to the system's needs to ensure stable operation of the system.

A vessel for sequestering carbon includes a cavity associated with a first opening and a second opening. The vessel is configured to perform a first operating mode to collect seaweed into the cavity and a second operating mode to discharge the seaweed collected in the cavity for sequestration. In the first mode of operation, the vessel is moved across the sea surface, such that water and floating seaweed pass into the cavity via the first opening. The second opening is provided with a filter, such that seawater is able to exit the cavity via the filter, but the seaweed is retained by the filter in the cavity. In the second mode of operation, the vessel is submerged to a transition depth at which the collected seaweed is compressed by water pressure to have a density greater than the sea density. The collected seaweed is then discharged from the cavity to sink to the seabed for sequestration.
