ABSTRACT:
An anchor for personal watercraft provides a generally cylindrical housing closed at a top end and enclosing a concavity formed through the opposite, bottom, diametral end. The opening of the concavity is defined by a circumferential edge of the housing, and may be further shaped or formed with a circumferential edge or with a central and/or a plurality of circumferential spikes to readily engage with any of a variety of materials found on the floor of a water body or beach. A weight may be removably attached to either the top side or within the concavity at the bottom side of the anchor, thereby functioning as additional ballast as may be necessary to overcome natural buoyancy of any air trapped in the concavity when the anchor is lowered into an anchoring position, or to overcome heavier seas.
