Nautical Term: Sea anchor
Definition of Sea anchor
A sea anchor, also known as a drogue, is a heavy, drag-creating device that is thrown overboard to prevent a vessel from drifting too far when being subjected to strong winds and rough seas. For instance, during a sailing race, if a sailor encounters a sudden, violent storm, he may decide to drop a sea anchor to keep his vessel headed into the wind and sea, thus minimizing the risk of capsizing or suffering extensive damage.
