Abstract

See full text

The present invention provides an apparatus and method of a dock system for launch and recovery of a stowed boat, which is capable of launching and recovering the boat during navigation of a marine vessel at a high headway speed. The launch and recovery apparatus has a stern dock (2) for accommodating the boat (10) therein. The apparatus launches the boat outboard through a stern opening and recovers the boat from the outboard area by entry of the boat into the dock. The apparatus is provided with a conduit device (11) so that seawater surrounding the vessel is drawn through an intake port (12) and is delivered to the dock through an outlet port (13). In the dock, a backward water stream is generated, which is to be discharged outboard through the stern opening.
