ABSTRACT:
An anchor includes at least one plow-like fluke, a shank, and a float. The relative position of the float with respect to the center of gravity of the combined shank and fluke causes the anchor to assume a generally upright orientation quickly once the anchor is dropped in the water. One end of the shank is attached to the fluke and the float is attached to a rearward portion of the shank, with the float's center of buoyancy spaced away from the connection to the fluke. Upon being put in the water, the anchor quickly assumes a generally upright orientation, i.e., shank up and fluke tip down. Once in the generally upright orientation, the anchor may gently rock side to side with a pendulum-like action, with the tip of the fluke preferably being the lowest point of the anchor, during its descent to the bottom. When the anchor reaches a soft bottom, the tip of the fluke penetrates the bottom and the momentum of the anchor causes at least a portion of the fluke to bury into the bottom in a generally upright orientation. This setting of the anchor may be achieved in most or all situations without dragging the anchor along the bottom. The anchor is particularly adapted for watercraft where storage space is a concern and for shallow water watercraft.
