A watercraft has a deck; central, left and right pods connected to a bottom of the deck; and a helm assembly disposed on the deck. The central pod is laterally centered relative to the deck. The central pod has a central hull defining a central tunnel, a motor connected to and disposed at least in part in the central hull, and a jet propulsion system disposed at least in part in the tunnel and operatively connected to the motor. The left pod is disposed at a left of the central pod and is laterally spaced from the central pod. The left pod has a left hull that is narrower than the central hull. The right pod is disposed at a right of the central pod and is laterally spaced from the central pod. The right pod has a right hull that is narrower than the central hull.

A system for autonomous ocean data collection includes at least one sensor capable of collecting sensor data, at least one transmission device, and at least one computing device comprising one or more hardware processors and memory coupled to the one or more hardware processors, the memory storing one or more instructions which, when executed by the one or more hardware processors, cause the at least one computing device to generate data for transmission based on the sensor data collected by the at least one sensor, and cause the at least one transmission device to transmit the data.

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.

A device for coupling a propulsor to a marine vessel. A rail is configured for attachment to the marine vessel. A carriage is moveable relative to the rail into first and second positions. A shaft has a first end pivotally coupled to the marine vessel and a second end for coupling to the propulsor. An actuator is configured to pivot the shaft relative to the marine vessel to thereby move the propulsor into and between stowed and deployed positions. A lock is manually operable to fix the carriage in the first position in which the actuator prevents manual pivoting of the shaft and alternatively in the second position in which the shaft is permitted to be manually pivoted.

Disclosed is a motorised wave-piercing ship with hull with a deck, the ship including a conning tower and, under the hull, a weighted keel, the keel being removable and being able to be placed in a low position and a high or extracted position. According to the invention, the ship can sail as a monohull or as a trimaran, the hull including a device for removable attachment of an anti-roll stabilisation system including an elongated connection arm terminated at its two lateral ends by two floats, the connection arm including an attachment member, the attachment member being configured to be removably attached on the attachment device in order to transform the ship into a trimaran, and the ship is monohull in the absence of the anti-roll stabilisation system.

A device for coupling a propulsor to a marine vessel. The device includes a mounting bracket configured for attachment to the marine vessel. A support frame has a carriage and is configured for the propulsor to be coupled thereto, where the carriage is configured to slidably engage with the mounting bracket into a fixed position. A member is manually engageable to prevent the carriage from sliding out of the fixed position. The propulsor is coupled to the marine vessel by sliding the carriage into the fixed position and engaging the member, where the propulsor is operable to propel the marine vessel in water when the carriage is in the fixed position, and where the propulsor is configured for decoupling from the marine vessel by disengaging the member and sliding the carriage out of engagement with the mounting bracket.

A floating solar array having a grid of structural members with openings therebetween and supporting pontoons underneath. One or more floating solar PV modules are positioned in each of the openings and elastic connectors are used to isolate these floating solar PV modules from the movement of the structural member grid. A first end of each of the elastic connectors are connected to the structural members or to one of the grid supporting pontoons, while a second end of each elastic connector is connected either to a PV module supporting pontoon or to the PV module mounted thereon. Together, these elastic connectors allow for limited linear and torsional movement of each of the floating solar PV modules with respect to the structural member grid.

The invention relates to a floating structure, comprising a plurality of interconnected frames and a plurality of buoyant members supporting the structure, wherein the frames are substantially triangular in planform. Adjacent triangular frames may be movably connected, in particular pivotably connected. The triangular frames may comprise right-angle triangles, isosceles triangles or equilateral triangles. The floating structure may support an installation, like e.g. a solar farm. The invention also relates to a triangular frame for use in such a floating structure.

A pontoon boat includes port and starboard pontoons and cross members connecting the pontoons. A shock absorber may be installed at each point of connection of the pontoons to the cross members. A cross member may be embodied as a double-webbed beam having first and second parallel flanges and first and second webs disposed between and connected to the flanges. Each pontoon may include a two-stage lifting strake having a first surface and a second surface inclined from the first surface.

A system for autonomous ocean data collection includes at least one sensor capable of collecting sensor data, at least one transmission device, and at least one computing device comprising one or more hardware processors and memory coupled to the one or more hardware processors, the memory storing one or more instructions which, when executed by the one or more hardware processors, cause the at least one computing device to generate data for transmission based on the sensor data collected by the at least one sensor, and cause the at least one transmission device to transmit the data.
