Project Description

A drogue (also known as a storm drogue) is a device external to a boat, attached to the stern and used to slow the boat down in a storm and to keep the hull perpendicular to the waves. The boat will not speed excessively down the slope of a wave and crash into the next one nor will it broach. By slowing the vessel in heavy weather, the drogue can make it easier to control. A drogue is usually constructed to provide substantial resistance when dragged through the water, and is trailed behind the vessel on a long line. A properly functioning drogue should also prevent pitch poling. Historically there have been limitations to design use of drogues for large vessels due to the rigidity and shock loads in violent conditions.  Marine Flex products can now be employed on large scale devices to attenuate such shock loads enabling safe deployment in extreme conditions
