  • Patent number: 10953284
    Abstract: A system, methods and apparatus for powered monofin that propels a swimmer through water uses one of two modes of power: 1. An electric-assist mode, in which the propulsor responds to a swimmer's kick by multiplying the work of the swimmer; 2. Inverse mode, in which the propulsor deactivates when the swimmer is working. In this mode, propulsion is inversely related to the work of the swimmer. As the swimmer does more work, power from the monofin is reduced, to a predetermined, average level of propulsion. As the swimmer does less work propulsion increases to the predetermined level.

The wheel retraction mechanism has a retraction linkage (14, 16, 18), pivotably connectable to the vehicle, and an actuator (38) for moving the wheel suspension between a protracted position for land use and a retracted position for use on water. The retraction mechanism supports the suspension unit spaced apart transversely from the vehicle. Tie bar (16) is connected to upper retraction arm (14) at an intermediate location (30) to ensure a large angle of tilt on retraction, to ensure that the wheel is retracted above hull line (156). The wheel suspension does not have to be compressed on retraction.

  • Patent number: 10946936
    Abstract: A rope guide apparatus to assist with mooring a vessel comprises an elongate pole and a length of rope. The length of rope is slidably retained by the elongate pole at a first point of retention adjacent a first end of the pole. The rope extends from the first point of retention towards a second end of the pole where it is slidably retained by the pole at a second point of retention adjacent the second end. The rope extends from the second end of the pole back towards the first end and is slidably retained at a third point of retention, with the rope extending freely from the pole. This apparatus allows easier one-person mooring of a vessel by looping the rope over a bollard and avoids the need for the individual to lean out of a vessel when attempting to moor at a distance.
