sea anchor

n. drogue, device used to hold a ship in one place while at sea

device used to hold a ship in one place while at sea

A sea anchor, used to stabilize a boat in heavy weather, anchors not to the sea floor but to the water itself, as a kind of brake. Sea anchors are known by a number of names, such as drift anchor, drift sock, para-anchor, and boat brakes. These all function the same way, by pulling large amounts of water along as the boat moves, and they are all used to counter the effects of high winds. Similar in design and use to the sea anchor is the relatively smaller drogue.
