摘要： A paddle assistance and propulsion system for use with personal watercraft is disclosed. The paddle assistance and propulsion system may include different mounting techniques that allow a propulsion device (e.g., a motor) to be coupled to various types of personal watercraft. Some mounting techniques may include the use of magnets to couple a motor-side mount to a boat-side mount. The paddle assistance and propulsion system may also utilize a variety of sensors in combination with control systems to provide various types of paddle assistance and different types of paddle assistance modes for the user of the personal watercraft.

摘要： Disclosed is a system and method for regenerating and distributing energy, such as employed on a vessel or floating offshore installation, the system including a first power distribution system, a second power distribution system electrically isolated from the first power distribution system, and a flywheel mechanically connected to both the first and second power distribution systems. Each of the first and second power distribution systems may include a motor/generator mechanically connected to the flywheel and a drive module electrically connected to its respective motor/generator. The flywheel drive modules may be connected to a common flywheel control module that includes a control algorithm for operating the system.

摘要： A noise reduction system for a marine vessel having a plurality of marine propulsion devices including a first marine propulsion device and a second marine propulsion device, each of the plurality of marine propulsion devices including a drive source, each of the drive sources operating on a same principle as that of the other drive sources, and including a rotary member. The noise reduction system includes a controller configured to control rotation of the rotary member of the drive source in the second marine propulsion device, to thereby control a phase of a second noise caused thereby, such that a first noise caused by rotation of the rotary member of the drive source in the first marine propulsion device is canceled by the second noise.

摘要： An outboard motor support device includes a transom connection mechanism, a pivot joint, and a motor support. The transom connection mechanism engages directly with a transom bracket to maximize stability and is configured to provide a consistently correct angular orientation of the motor support relative to the motor during use. In particular, the pivot joint adjustably aligns to the motor is a desired orientation during assembly to ensure a firm and “nested” engagement with the lower unit of the motor in the motor support. The motor support can be designed to fit specific motors, allowing for maximum stability and maximum surface area contact when properly aligned and engaged with the motor. The present outboard motor support device is formed as a single unit that provides vertical support as well as horizontal stabilization to the motor during transit, thereby also preserving the transom brackets and tilt/trim mechanism of the motor.

摘要： A modular catamaran is a small body catamaran capable of being easily disassembled. The catamaran has approximate dimensions of ten feet-four inches (10′-4″) long and ninety-five and a half inches (95½″) wide having a pair of foam filled fiberglass pontoons. The top of the catamaran is fabricated with a welded aluminum frame that may be provided complete with seats and an engine.

摘要： A supporting structure for an outboard engine. The supporting structure includes an adapter plate for supporting an electric motor having an output shaft for outboard propulsion. Further, the adapter plate supports an invertor for driving the electric motor. The adapter plate includes an output port for fluid tight passage of the electric motor output shaft through the adapter plate.

摘要： An outboard motor includes an engine, and a propeller driven by the engine via a drive shaft and a propeller shaft, a tilting mechanism that changes a tilt angle of the propeller shaft and/or the drive shaft, a triaxial acceleration sensor and a triaxial angular velocity sensor, and a controller. The controller is configured to acquire at least one of a gravity direction, a traveling direction, or a horizontal direction of the hull using the triaxial acceleration sensor, and detect at least one of a first angle of the drive shaft with respect to the gravity direction, a second angle of the propeller shaft with respect to the traveling direction, or a third angle of the propeller shaft with respect to the horizontal direction using the triaxial angular velocity sensor, to thereby control the tilting mechanism to adjust the tilt angle of the drive shaft and/or the propeller shaft.

摘要： A stern and swivel bracket assembly for mounting a drive unit to a watercraft has a stern bracket having first and second laterally spaced portions, a swivel bracket pivotally connected to the stern bracket about a tilt/trim axis, and a hydraulic linear tilt-trim actuator operatively connected between the stern and swivel brackets. The swivel bracket includes a hydraulic steering actuator, and defines first and second hydraulic steer ports facing outward in a first lateral direction. The swivel bracket further includes at least one drive unit mounting bracket connected to the hydraulic steering actuator for connecting the drive unit to the swivel bracket. The hydraulic linear tilt-trim actuator is located laterally between the first and second portions of the stern bracket, and defines trim-up and trim-down hydraulic ports facing outward in a second lateral direction opposite the first lateral direction.
