Title: Vessel and apparatus for at-sea retrieval of buoys and anchors

Abstract: An at-sea buoy and anchor retrieval apparatus utilizes a vessel having a catamaran hull with a buoy catcher apparatus disposed between the hulls of the vessel. The buoy catcher is vertically movable so that it can be placed at the appropriate water depth to capture the buoys when the vessel is underway. A lift is provided to elevate the buoy catcher containing the buoy to the vicinity of an opening in the deck so that access to the buoy may be had from the deck.
