ABSTRACT:
A sea anchor may be lifted from the sea bottom by remotely inflating an inflatable float connected to the anchor. The inflated float provides a buoyant lift force that automatically lifts the anchor to the water surface or assists a person in lifting the anchor to the surface. The anchor may be lowered to the sea bottom by venting air out of the float from a remote point on the water surface.
