Description

Most staysails are triangular; however, some are four-cornered, notably some fisherman's staysails. Triangular staysails set forward of the foremost mast are called jibs, headsails, or foresails. The innermost such sail on a cutter, schooner, and many other rigs having two or more foresails is referred to simply as ''the staysail'', while the others are referred to as jibs, flying jibs, etc. Types of staysail include the tallboy staysail (a narrow staysail carried between the spinnaker and the mainsail on racing yachts), the genoa staysail (a larger one carried inside the spinnaker when broad reaching), and the bigboy staysail (another name for the shooter or blooper, carried on the leeward side of the spinnaker). Unlike the cutter staysail, none of these sails have their luff affixed to a stay. On large rigs, staysails other than headsails are named according to the mast and mast section on which they are hoisted. Thus, the staysail hoisted on a stay that runs forward and downwards from the top of the ''

Uses

In square rigged ships the staysails can help in tacking, overcoming the lumbering square sails' tendency to prevent bearing up to windward, especially in light winds. Where a ship attempts to tack but fails and has to bear away again on the original tack, she is said to have missed her stays. In cutter rigged yachts the genoa will often need to be furled before changing tack due to the difficulty in passing the big sail between the two forestays. Here the staysail can help bring the bow through the wind more effectively.
