Abstract: An anchor having release capabilities includes a pair of generally planar and spaced-apart flukes joined to a cylindrical tube. A shaft is located intermediate the flukes, the tube passing through the shaft to provide 360.degree. movement between the flukes and shaft. The shaft includes spaced-apart and parallel plates adjacent the tube. A rod is disposed within the tube and a perpendicular trigger is attached thereto, the trigger extending through an opening in the tube. The rod is retained between the plates of the shaft by a replaceable, breakable tie. A locking ring element may be used with the anchor to prevent the release capability. The ring is slidable over the plate portion of the shaft to maintain the rod therebetween. A float may be employed with an anchor to prevent entanglement with obstructions such as the superstructures of submerged vessel. The float is coupled to the anchor shaft by a length of rope, cable, or chain so that the float remains below the water surface.
