Abstract

An anchor (10) includes at least one fluke (20), a shank (40), and a float (60). 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. When the anchor reaches a soft bottom, the tip (22) 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. The fluke preferably includes two forward pointing tines (130), each tine comprising a pointed tip, a wing surface (30), a longitudinal fold (138) extending parallel to the longitudinal axis (25) of the fluke and an outboard surface (136). The wing surfaces are canted with respect to each other and are arranged inward of the respective longitudinal folds.
