  • Batten
    A sail batten is a flexible insert in a sail, parallel to the direction of wind flow, that helps shape its qualities as an airfoil. Battens are long, thin strips of material, historically wooden but today usually fiberglass, vinyl, or carbon fiber, used to support the roach of a sail. They are also used on […]
  • Bolt Rope
    A bolt rope (Variants: “bolt-rope” and “boltrope”, French: ralingue, Spanish: relinga, Old Norse: *rár-línk, comprising rár genitive of rá “rope” and línk “edge of a sail “), is the rope that is sewn at the edges of the sail to reinforce them, or to fix the sail into a groove in the boom or in […]
  • Clew
    The corner where the leech and foot connect is called the clew on a fore-and-aft sail. On a jib, the sheet is connected to the clew; on a mainsail, the sheet is connected to the boom (if present) near the clew. Clews are the lower two corners of a square sail. Square sails have sheets […]
  • Cringle
    A cringle is an eye through which to pass a rope. In nautical settings, the word refers to a small hole anywhere along the edge or in the corner of a sail, rimmed with stranded cordage and worked into the boltrope. Typically it encloses a metal grommet for reinforcement and to reduce wear. In this […]
  • Foot
    The lower edge of any sail.
  • Head
    In a triangular sail, the corner where the luff and the leech connect is called the head. On a square sail, the top corners are head cringles, where there are grommets, called cringles. Reference: Wikipedia
  • Leech
    The aft or trailing edge of a fore-and-aft sail; the leeward edge of a spinnaker; a vertical edge of a square sail. The leech is susceptible to twist, which is controlled by the boom vang, mainsheet and, if rigged with one, the gaff vang. Reference: Wikipedia
  • Luff
    The forward edge of a sail. Reference: Wikipedia
  • Peak
    On a quadrilateral sail, the peak is the upper aft corner of the sail, at the top end of a gaff, a sprit or other spar. Reference: Wikipedia
  • Tack
    The corner on a fore-and-aft sail where the luff and foot connect is called the tack and, on a mainsail, is located where the boom and mast connect. On a square sail underway, the tack is the windward clew and also the line holding down that corner. Reference: Wikipedia
  • Tell-Tale
    In a nautical or sailing context a tell-tale, also known as a tell-tail, is a piece of yarn or fabric attached to a stay, any of several wires which hold a mast in place on a sailboat. they are used in pairs, on each side of the jib; there will be one tell-tail on the […]
  • Throat
    On a quadrilateral sail, the throat is the upper forward corner of the sail, at the bottom end of a gaff or other spar. Gaff-rigged sails, and certain similar rigs, employ two halyards to raise the sails: the throat halyard raises the forward, throat end of the gaff, while the peak halyard raises the aft, […]
