In sailing, "track" (or course made good) refers to the actual path a boat travels over the ground, accounting for wind and current. It differs from the heading (where the bow points) due to leeway or drift. "Track" can also refer to a metal fitting on a mast, boom, or deck that guides sails or cars.

Key Aspects of "Track" in Sailing:
Course Over Ground (COG): The actual, intended, or completed path of the vessel over the seabed.

Water Track (Course Through Water): The direction of the yacht through the water, determined by the heading adjusted for leeway, but not tidal current.

Distinction from Heading: The heading is the direction the boat is pointed, while the track is where it is actually going.

Fittings: Tracks (hardware) are used for attaching sails to the mast/boom, or for adjustable sheet leads known as "travellers".
