Abstract: An anchoring device particularly for securement of an umbrella, and may also be used in soft or hard materials. The anchoring device is comprised of a tubular body having an outer surface and an upper end and a tapering lower end, the lower end includes a penetrating tip extending longitudinally from the tubular body, the penetrating tip further having a plurality of lateral extensions capable of breaking hard ground, and a plurality of laterally extending baffles about the outer surface of the lower end of the tubular body, each of the baffles having a front edge proximal and a rear edge distal to the lower end of the tubular body. The front edges are substantially the same distance from the penetrating tip, whereby the lateral extensions break the ground or material preceding the front edges of the baffles as the body rotates.

Abstract: A marine propulsion system comprised of a housing unit having forward and rearward openings, a rotational unit, having forward and rearward openings and having an inner and outer periphery, rotatably secured in the housing unit such that the forward and rearward openings are aligned with the forwards and rearward openings of the housing unit, a plurality of blades rigidly secured to the inner periphery of the rotational unit, and drive means which rotate the rotational unit within the housing unit. Operation of the drive means causes the rotation of the rotational unit and the blades direct water into the forward openings of the housing unit and the rotational unit and out the rearward openings of the housing unit and rotational unit, thereby creating thrust.
