In sailing, tack is a corner of a sail on the lower leading edge. Separately, tack describes which side of a sailing vessel the wind is coming from while under way—port or starboard. Tacking is the maneuver of turning between starboard and port tack by bringing the bow (the forward part of the boat) through the wind. Jibing is the maneuver of turning from one tack to another by bringing the stern (rear of the boat) through the wind.
As a part of a sail, the tack is the lower corner of the sail's leading edge. On a sloop rigged sailboat, the mainsail tack is connected to the mast and the boom at the gooseneck. On the same boat, a foresail tack is clipped to the deck and forestay.
