restraint consisting of a canvas covered frame that floats behind a vessel; prevents drifting or maintains the heading into a wind

a cone-shaped under water wind sock, similar to those at airports that detect changes in wind direction

a drogue, or canvas bag, that has great resistance to being pulled through water

a funnel shaped bag which will keep the bow pointed into the seas

a drag of floating construction and is so shaped as to offer maximum resistance to sea when thrown over the vessel; used when anchoring is impossible and necessary to keep vessel head to sea; also known as drogue

Cone shaped, made of canvas, open at one end or both ends. Equipped with a tow-line at the large end and a tripping line at the other. Designed to keep the bow of the life raft heading into the seas.

Any device used to reduce a boat's drift before the wind.

A canvas, cone-shaped device deployed to keep the bow headed into the wind to help safely ride out a storm. Also called a drogue.

A device designed to bring a boat to a near stop in heavy weather. Typically, a sea anchor is set off the bow of a boat so that the bow points into the wind and rough waves.

A sea anchor, used to stabilize a boat in heavy weather, anchors not to the sea floor but to the sea itself, as a kind of brake. Usually shaped like a parachute or cone, it is fed out from the ship or boat so that it fills under water; floating sea anchors intended to drag on the surface of the water have also been used. A long line (typically between ten and fifteen boat lengths) is attached to the sea anchor and the bow of the boat or ship.
