Systems, methods, and apparatuses are described herein for providing electrical power to a marine vehicle. In some aspects, a marine vehicle includes a power system arranged to receive and store electrical power delivered from a solar panel assembly. The power system may include one or more batteries. The vehicle also includes a processor arranged to determine an extension time and an retraction time for a solar panel assembly and a controller that, in response to instructions from the processor, is arranged to extend the solar panel assembly and retract the solar panel assembly. The solar panel assembly is arranged to be configured in at least one of an extended position and a retracted position. The solar panel assembly includes one or more solar panels where the solar panel assembly is in electrical communication with the power system.

An apparatus for the management of one or more power sources when connected to one or more batteries, in particular on a boat, comprises a first power source such as an engine alternator 11 connected to a first source charge manager 26 and a second power source such as a solar panel 13,14 connected to a second source charge manager 26. The first and second source charge managers 26 are connected to a rail 5 maintained over a predetermined range of voltage. The rail 5 is connected to a battery charge manager 33, which manager is connected to a battery such that the battery can be charged from at least one of the first and second power sources.

Implementations of communication devices may include: a housing having a hollow compartment in a waterproof shell. The waterproof shell may be configured to float on a surface of water. The communication device may include a computing system having a memory and a processor within the hollow compartment of the housing. The communication device may include an onboard power unit electrically coupled with the computing system. One or more radios may be coupled with the housing and with the onboard power unit and the computing system. The one or more radios may be configured to act as a gateway by receiving data from one or more watercrafts and transmitting the data to one or more receivers over a radio telecommunication channel.

Disclosed herein are hydrofoil vessels and systems integrated with renewable energy sources. In one aspect, the hydrofoil vessel includes one or more hulls, an omni-directional platform connecting the one or more hulls of the hydrofoil vessel. The omni-directional platform may include at least one of: a sail, a wind turbine, a solar panel, a hydroelectric motor, a hydrofoil controller platform, and a battery component. Also disclosed herein are methods and computer readable medium for controlling an omni direct modular hydrofoil vessel having one or more hulls integrated with renewable-energy sources.

The disclosure relates to a method for operating an internal combustion engine of a watercraft, in particular on inland waters, in which (i) in an electrolysis unit for the production of hydrogen, water is split into hydrogen and oxygen, (ii) a carbon dioxide sorption unit extracts carbon dioxide from the ambient air, (iii) the hydrogen and the carbon dioxide are fed to a methanol synthesis unit for the production of methanol, and are synthesized therein to methanol, (iv) a photovoltaic unit absorbs solar energy and converts it into electrical energy. The electrolysis unit, the carbon dioxide sorption unit and the methanol synthesis unit are powered by the electrical energy generated in the photovoltaic unit. The methanol produced is transported by means of a distributor system to at least one tank of the watercraft, and is fed from the tank as required to the internal combustion engine, and therein is combusted to generate mechanical energy.

A watercraft, in particular a SWATH-type yacht is intended to have improved and greater functional properties. To this end, the watercraft, in particular a SWATH-type yacht, has upper works that receive a structure, and on the underside thereof, i.e. the wet deck, two stilts, i.e. partial hulls are arranged which are spaced apart from one another transversely in the direction of travel. Each partial hull is positioned on a submerged hull which is arranged substantially in the direction of travel of the watercraft and extends over at least part of the upper works. The submerged hulls have characteristic narrowed portions in cross section, which portions are formed on the longitudinal extension of swimmer profiles of the partial hull.

A plurality of rolling pontoons with or without a plurality of protrusions (paddles) and their use on amphibious vehicles and watercraft. The application of tires, power, suspension, paddle designs, towing apparatus, pontoon geometry and/or a plurality pontoon arrangements that will allow said vehicle to be towed without a trailer, easily and quickly traverse a variety of environments, and/or maneuver a variety ways. The further addition of electric motors, solar panels, and batteries allow efficient electric amphibious vehicle/watercraft and provide battery backup and power for a residence. A method of manufacture is defined with the modular application of said electrical drivetrain to new or existing amphibious vehicles or watercraft.

Implementations of communication devices may include: a housing having a hollow compartment in a waterproof shell. The waterproof shell may be configured to float on a surface of water. The communication device may include a computing system having a memory and a processor within the hollow compartment of the housing. The communication device may include an onboard power unit electrically coupled with the computing system. One or more radios may be coupled with the housing and with the onboard power unit and the computing system. The one or more radios may be configured to act as a gateway by receiving data from one or more watercrafts and transmitting the data to one or more receivers over a radio telecommunication channel.

A watercraft includes a pair of inflatable pontoons. Releasably affixed atop each of the pontoons and aligned therewith are inner and outer lengthwise frame members. Forward and aft beamwise frame members are affixed to the inner and outer lengthwise frame members. Primary arch members are affixed to the forward and aft beamwise frame members. A main fabric panel is stretched between the pair of primary arch frame members, the forward beamwise frame member, and the aft beamwise frame member. A motor mount is affixed centrally to the aft beamwise frame member, the motor mount being configured to removably support a motor assembly. Aft panel side members are rotatably-lockably affixed to the aft beamwise frame member and joined by an aft panel top member. An aft fabric panel is stretched between the aft panel side members, the aft beamwise frame member, and the aft panel top member.

A solar-powered boat comprising a hull which comprises a bottom panel and side panels extending upwardly from opposed sides of the bottom panel for defining a hull interior region. At least one of the side panels comprises an upper section angled inwardly with respect to an axis orthogonal to the bottom panel; and at least one panel opening provided in the upper section. The solar-powered boat is further comprised of at least one solar panel configured to supply electricity to the boat, the solar panel being mounted within the panel opening using a solar panel mounting kit.
