Warping (sailing)

Warping or kedging is a method of moving a sailing vessel, typically against the wind or out from a dead calm, by hauling on a line attached to a kedge anchor, a sea anchor or a fixed object, such as a bollard. In small boats, the anchor may be thrown in the intended direction of progress and hauled in after it settles, thus pulling the boat in that direction, while larger ships can use a boat to carry the anchor ahead, drop it and then haul.
