PROPULSION SYSTEM FOR A WATERCRAFT

A mount for mounting a drive module to a watercraft is described herein. The mount in-use with the drive module is also described. The mount in-use with the drive module and the watercraft is also described. The mount includes a frame configured to be attached to the watercraft. The mount is also configured to attach to the drive module to selectively allow the drive module to translate from a first position to a second position. When in the first position, the drive module is capable of propelling the watercraft. The frame has a retainer to fix the drive module in the first position and a first spring to assist translation of the drive module toward the second position. The second position is a relatively raised position compared to the first position.

A dual drive system for providing motive power to a watercraft has a frame configured for connecting to the watercraft and a drive assembly connected to the frame. The drive assembly has a manual drive mechanism configured for receiving mechanical input from a user, a motor drive mechanism configured for receiving mechanical input from a motor, a driveshaft having a first end in selective engagement with one of the manual drive mechanism and the motor drive mechanism and a second end in engagement with a propeller, and a drive selector for selectively engaging the manual drive mechanism or the motor drive mechanism with the driveshaft based on a position of the drive selector between first and second positions. In the first position, the drive selector engages the manual drive mechanism with a driveshaft. In the second position, the drive selector engages the motor drive mechanism with the driveshaft.

Watercraft with pedal-drive mechanism

In one example, a watercraft includes a hull that defines a well extending through a bottom of the hull, and the hull defines an upper tray recess and a lower tray recess. A pedal-drive mechanism is connected to the hull and configured to assume both a stowed position and a deployed position, and a portion of the pedal-drive mechanism extends through the well when the pedal-drive mechanism is in the deployed position. A pedal-drive housing and attachment mechanism is provided that includes a tray configured to move between a forward position in which part of the tray resides in the lower tray recess, and an aft position in which part of the tray resides in the upper tray recess.

The interface also comprises fastening assemblies for removably fastening the second portion to the first portion of the interface, and a guiding assembly for maintaining the channel of the second portion in registry with the hole of the first portion.

Modular hybrid propulsion unit for watercraft
11591059 · 2023-02-28 · ·

A modular hybrid propulsion unit is disclosed that is mountable to a watercraft. According to an example, the modular hybrid propulsion unit includes a housing configured to fit within a complementary housing receiver on a topside of the watercraft, and a rotational output coupling configured to rotationally engage with a rotational input coupling for a propeller of the watercraft. The propulsion unit further includes an electric motor within the housing, the electric motor having a motor shaft connected to the rotational output coupling for providing an electrically powered rotational input to the rotational output coupling. The propulsion unit further includes a crank having one or more crank arms. The crank is connected to the rotational output coupling for providing a human powered rotational input to the rotational output coupling independent of the electrically powered rotational input by the electric motor.

Personal hand and foot operated watercraft

A watercraft includes at least one floating member, a central frame supported thereon, first and second foot platforms, and first and second handlebars. The first and second handlebars define elongated configurations and include grasping end portions, intermediate portions pivotably coupled to the central frame, and base end portions pivotably coupled to first end portions of the respective first and second foot platforms. A propulsion system includes an axle assembly, first and second rotating arms, and first and second oars. The rotating arms are fixed relative to one another, pivotably coupled about the axle assembly at first ends, and pivotably coupled to second end portions of the foot platforms at second ends. The oars are engaged with and extend from the foot platforms. The propulsion system cycles the oars approximately 180 degrees out of phase to propel the watercraft while maintaining substantially perpendicular orientation of the oars.

Watercraft and associated pedal drive system

A watercraft and associated pedal drive system are provided. Method of operating the pedal drive are also provided. The pedal drive system allows for unassisted manual pedaling to provide thrust to the watercraft. The pedal drive system also provides on demand pedal assistance of varying levels via an assist drive train having an electric motor to supplement the manual pedal force input provided by a user at the pedals of pedal drive system.

Propulsion apparatus for watercraft
11485465 · 2022-11-01 ·

A watercraft propulsion apparatus includes an eccentric crank assembly operatively connected to a pair of fins adapted to sweep back and forth in a generally transverse direction relative to a longitudinal axis of the watercraft. The fins may be rotatable about a first axis coplanar to the longitudinal axis of the watercraft. A drive linkage assembly operatively connecting the eccentric crank assembly to the pair of fins imparts a torque force to oscillate the pair of fins. The oscillating fins provide a propulsive force to propel the watercraft longitudinally forward during both oscillating directions of the fins as they sweep back and forth.
