Drogue

A device, often resembling a small parachute or cone, deployed from a vessel or lifeboat to create drag and stabilise its movement in rough seas.

A drogue is an essential piece of equipment used in maritime operations, particularly in challenging sea conditions. Its primary function is to slow down a vessel or lifeboat by increasing drag, which helps to prevent uncontrolled drifting or broaching (when a vessel turns broadside to the waves, risking capsizing). The drogue is typically deployed off the stern (rear) of the vessel and is connected by a line or cable. It can take various forms, but the most common design is a conical or parachute-like structure made from durable fabric or other materials capable of withstanding the forces of the water.

In heavy seas, a vessel can become difficult to control, especially if it is moving too quickly or being pushed by strong winds and waves. By deploying a drogue, the vessel’s speed is reduced, and its stern is kept facing into the waves, improving stability and safety. This can be particularly useful for smaller vessels or lifeboats, which are more vulnerable to capsizing in rough conditions.

Drogues are also used in some fishing operations to maintain a steady position or slow down the drift of a boat while nets or lines are deployed. In essence, the drogue is a vital tool for enhancing safety and control in adverse maritime environments, offering a simple yet effective solution to the challenges posed by rough seas.
