The invention relates to a motorization system for an electrically assisted craft which is intended to allow a user to be transported on water, the invention being used particularly in the field of surfboards, paddleboards or sailboards, and in the field of kayaks or canoes.

The electric motorization system is configured to be connected to an electrical energy source and comprises, on the one hand, a watertight enclosure 1 which is intended to be integrated in or on a craft, in which enclosure 1 a rotor 2 and a stator 3, 7 are arranged, and, on the other hand, a shaft 4 which is connected at a first end to the rotor 2 and which protrudes in a watertight manner outside the enclosure 1 at a second end opposite its first end. The shaft 4 can be connected at its second end to propulsion means of a craft, such as a propeller, so that when the system is supplied with electrical energy, the rotor 2 is rotated and drives the shaft 4 with this rotation.

The system also comprises cooling means 5 which themselves comprise at least one first elongate assembly 5, which is at least partially made of metal, and a first end of which is arranged inside the enclosure 1, the elongate assembly 5 protruding in a watertight manner outside the enclosure 1 at a second end opposite its first end so as to allow conduction of the heat from the inside to the outside of the enclosure 1 along the first elongate assembly 5.

A propulsion system for a seagoing vessel includes a rotatable frame and either (a) at least two masts coupled to the frame and each having a sail and a boom, or (b) at least two blades coupled to the frame. The rotatable frame and either the rotatable boom or at least two blades may be locked in position in a locked mode and unlocked and freely rotatable in an unlocked mode. A control system that is in communication in communication with a frame lock and either a boom lock or a blade lock and may be configured to determine when the vertical axis wind turbine should be in either the locked mode or the unlocked mode based on the direction of the wind and a direction that the seagoing vessel is traveling.

A solar electric pump-out boat for removing human waste. The pump-out boat may include a boat hull, wherein the boat hull may include a bow, a stern, and a self-draining sole disposed therein. The pump-out boat may further include a holding tank disposed within the hull underneath the self-draining sole for collecting waste. The pump-out boat may further include a console disposed approximately center of, and on a top surface of the self-draining sole. The pump-out boat may further include a solar panel for absorbing sunlight to convert into electrical power. The pump-out boat may further include a pump disposed within the console. The pump-out boat may further include a battery connected to a motor, the pump, and the solar panel, such that the solar panel charges the battery to provide the electrical power to operate the pump and the motor.

A Hybrid Vessel Propulsion and Generation System diesel jet drive outboard and inboard motors, with an electrical generator attached to a prop shaft of the motors to generate electricity to power batteries. On large boats or ships with a gear change, the generator is mounted on the back of the gearbox and is attached to the prop shaft, with the generator being driven by rotation of the prop shaft and the drive of the gearbox. The system also incorporates electrically powered water thrusters and mechanical pressurised water turbines used for charging the batteries. The system also incorporates electric motors attached to propellers powered by electric batteries. Solar panels may be arranged in the port hole windows incorporating a housing, latch and lever arms to position them towards the sun.

A watercraft includes a positioning system having a controller and at least two stationary mounted propulsion units that are stationary with respect to the watercraft for generating a forward and backward thrust with respect to the respective propulsion unit in a respectively fixed direction with respect to the watercraft. The controller is arranged for individually controlling the thrust generated by each of the two propulsion units for moving and steering the watercraft.

A Pulsed Locomotor (120), for propelling media, fluids and crafts, in fluids and on land, comprising a blade (124) securely connected to a drive shaft (122). Upon reciprocation, the ambient medium is forced towards the trailing edge of the blade (124) thereby causing a reactive locomotion of the apparatus, substantially along the plane of the blade. Apparatus is secured to motor M by fastening through aperture (130). The apparatus can be operated directly by motor M, and indirectly by the reaction momentum imparted to a supporting platform P. Thrust is directed by steering handle (128) about a bearing (126), rotatably coupling to platform P and base C. Lubricant L is supplied to outlets (134) via conduit (136) and inlet (132), to coat the apparatus with a lubricant cavity, for drag reduction. The blade (124) planes along a figure 8 reciprocation path s1e1s2e2s1. Crafts are embodied.
