The term 'drogue' is a type of ANCHOR used to stabilize a vessel in water. It is typically made of canvas or other material and is attached to the stern of a boat. The drogue is designed to slow down the vessel's speed and prevent it from drifting too far away from its intended location. It is also used to help keep the vessel in a specific direction, such as when sailing in strong winds. In addition, drogues can be used to help reduce the effects of waves on a vessel.
