gooseneck n : something in a thin curved form (like the neck of a goose)
- Anything with a slender curved shape, resembling the neck of a goose, such as the shaft of some lamps.
- The swivel connection on a sailboat located near the bottom of the mast that the boom attaches to. When a sailboat performs a tack or a jibe the gooseneck swings the boom from one side of the boat to the other.
The gooseneck is the swivel connection on a sailboat by which the boom attaches to the mast. The boom moves from side to side and up and down by swiveling on the gooseneck.
The gooseneck may be a two axis swivel as pictured. Having an integrated shackle for the tack is common. Goosenecks on older rigs may be formed by a loop attached to the end of the boom that fits loosely about the mast.
