摘要： A board can have an upward-facing side arranged to enable a person to stand on the board while surfing. A motor can be attached to a downward-facing side of the board to propel the board. A computer system can use data from sensors and a steering system to actively respond to actions from the person riding on the board.

摘要： A boat includes a planing hull, a propeller, a main rudder, and a pair of flanking rudders. The planing hull has port and starboard sides, a transom, a hull bottom, and a centerline running down the middle of the boat, halfway between the port and starboard sides. The propeller is positioned forward of the transom and beneath the hull bottom. The main rudder is positioned aft of the propeller. The main rudder has a rotation axis about which the main rudder rotates. The flanking rudders are positioned forward of the propeller. One of the flanking rudders is positioned on the port side of the centerline, and the other flanking rudder is positioned on the starboard side of the centerline.

摘要： A ship propulsion unit includes: an engine including a crankshaft extending in a front-rear direction of a ship; a propeller shaft; a power transmission mechanism configured to couple the crankshaft and the propeller shaft; an upper case; and a lower case accommodating the propeller shaft and connected to the upper case. The power transmission mechanism includes a drive shaft extending from the upper case toward the lower case. The upper case and the engine are fixed to a ship body. A connection portion between the upper case and the lower case is provided with a rotation mechanism configured to rotate the lower case around an axis of the drive shaft.

摘要： A floating vessel with gearless pod propulsor and counter rotating propellers is secured to a hull, each pod having a lead propeller and a trailing propeller, each propeller connected to a shaft connected to either a stator and rotor or a hydraulic motor. A lead propeller turns in a first direction and a trailing propeller turns in an opposite direction simultaneously, generating thrust for the floating vessel along a thrust vector using the counter rotation of the trailing propeller to recover swirling energy from the lead propeller improving propulsive efficiency of the floating vessel. The pod is positioned below a water line of the floating vessel providing propulsion for the floating vessel without gears.

摘要： A thruster (1) for propelling a watercraft comprises at least one propeller (11, 12) on a rotatable propeller shaft (13, 14) and a motor (20) for driving the propeller shaft (13, 14) through a drive arrangement, particularly a drive arrangement comprising a rotatable drive shaft (31) and a coupling arrangement (32) arranged between the drive shaft (31) and an output shaft (22) of the motor (20) for coupling the drive shaft (31) to the output shaft (22) of the motor (20). The motor (20) is a permanent magnet motor, the stator body (21) of the motor (20) being provided with a recess (23) surrounding at least a part of the output shaft (22) of the motor (20), and the coupling arrangement (32) being at least partially located inside the recess (23) so that a 10 configuration having minimal constructional height is obtained.

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： A vertically adjustable jack plate configured to attach an outboard motor (or analogous device) to the transom of a marine vessel. A transom bracket is provided for connection to the vessel. A motor mounting plate is connected to the transom bracket. A lift jack vertically adjusts the position of the motor mounting plate with respect to the transom bracket. The lift jack incorporates a drive shaft that is used to vary an amount of extension or the lift jack. A handle is provided on the drive shaft. In operation, the user must preferably engage the handle to the drive shaft in order to turn the drive shaft. In a preferred embodiment the user must push the handle inward toward the lift jack in order to engage the handle to the drive shaft.

摘要： A lifting spindle arrangement is disclosed for a retractable thruster unit of a marine vessel, the lifting spindle having a lower end and an upper end and being supported at its lower end to a lower support structure by a lower support assembly and at its upper end to an upper support structure by an upper support assembly. The lifting spindle is provided at its both ends with a locking member for such a connection to the support structures such that each end of the lifting spindle may freely move in an axial direction away from the opposite end of the lifting spindle.

摘要： The drive unit is designed to be mounted on a marine vessel, including a mobile housing, and is able to pivot around an axis against the hull of the marine vessel. A drive shaft mounted rotary is against the mobile housing and is supported by two roller bearings. A propulsion element rotates in solidarity with the drive shaft. The propulsion unit has, at the front, at least two braking and locking systems of the drive shaft located in an area between the upstream rolling bearing and propulsion element.

摘要： A support strut has an upper end rotatable supported at a bottom of a vessel and a lower end supporting a casing. A first electric motor within the casing drives a propeller via a first shaft. An annular nozzle surrounds an outer perimeter of the propeller and is fixedly supported on the casing, with a support construction comprising at least three vanes extending in the radial direction between the outer perimeter of the casing and the inner perimeter of the nozzle. A duct for water flow is formed through the interior of the annular nozzle. The propeller pulls the vessel in a driving direction. The vanes are positioned after the propeller in the driving direction of the vessel, whereby the vanes are optimized for redirecting rotational flow components of the flow produced by the propeller into axial thrust.
