Abstract
A sea anchor is disclosed which comprises a generally cylindrical body of cloth or the like material open at the forward end. The opposite end is provided with a hem through which a rope or the like is passed to draw the opposite end more or less closed. Tow members are secured to the periphery of the sea anchor at the open end of the body, and a single control line is connected adjacent the opposite end of the body. Pulling on the control line independently of the tow members partially inverts or turns inside out the body of the sea anchor, thus reducing the maximum depth thereof, and greatly reducing the drag, thus to limit the anchoring effect, and to facilitate return of the sea anchor to a boat or the like.
