Jib

A triangular headsail set forward of a mast, normally with its luff supported by a stay or foil.

A jib is generally non-overlapping or less overlapping than a genoa, although terminology and size conventions vary. It may be hanked to a forestay, set in a luff foil or roller-furled, and specialised forms include working, storm and self-tacking jibs.

The sail contributes drive and affects balance and pointing ability. Halyard tension, sheet lead and sheet tension control luff shape, twist and angle of attack, while loaded sheets, flogging cloth and the foretriangle require care during tacks and sail changes.
