Abstract
A portable propelling system including a driver removably coupled to a drive end portion of a shaft, and a propeller connected to a prop end portion of the shaft. The shaft may extend through an outer casing. The driver may be configured to rotate the shaft and the propeller about a rotational axis of the shaft relative to the outer casing. One or more water-buoyant components, such as one or more sections of polymeric closed-cell foam, may be disposed around the outer casing. A flexible strap may be coupled to the outer casing. A first end portion of the flexible strap may be operable between a connected position and a towing position. The system may be a telescoping system operable between collapsed and extended positions along the rotational axis.
Claims20
A portable propulsion system for a watercraft, comprising:
- a telescoping shaft having a prop end portion, a drive end portion, and a rotational axis extending from the prop end portion to the drive end portion;
- a propeller connected to the prop end portion of the telescoping shaft;
- and
- a driver removably connected to the drive end portion of the telescoping shaft, the driver being configured to rotate the propeller via rotation of the telescoping shaft about the rotational axis to propel the watercraft;
- wherein the portable propulsion system is operable between an extended position and a collapsed position along the rotational axis, the extended position corresponding to the prop end portion being further away from the drive end portion than when in the collapsed position.
A portable propulsion system for a watercraft, comprising:
- a shaft having a prop end portion, a drive end portion, and a rotational axis extending from the prop end portion to the drive end portion;
- a propeller connected to the prop end portion of the shaft;
- a driver removably connected to the drive end portion of the shaft, the driver being configured to rotate the propeller via rotation of the shaft about the rotational axis to propel the watercraft;
- and
- polymeric foam disposed around the shaft between the drive end portion and the prop end portion.
