Sloop Mast, Mainsail and Jib
-
A sloop has one mast, two sails, a mainsail and a fore sail or jib. The mast and mast step are located forward of the middle waterline length of the boat. The mainsail is attached to the mast and boom that swings across the boat with the direction of the wind. The jib is attached to the forestay at the top of the mast forward of the mainsail.
Standing Rigging
-
A standing rig is usually made of stainless steel wire and is used to keep the mast in place. The mast is help up by wire shrouds and stays that run from the deck to fittings on the mast. The shrouds hold the mast on both sides. Stays hold the mast in place from the bow to the stern. The shrouds and forestays are attached to the mast with metal fittings. A backstay that runs from the top of the mast or masthead to the stern is attached to a hydraulic backstay adjustor to control forestay tension. The standing rigging does not move except with occasional adjustments when necessary.
-
Running Rigging
-
The running rigging is a collection of sheets (robe lines) and halyards. A halyard is a line used to raise the sail up the mast. One the sail is hoisted, it is controlled with a sheet. The sheet is adjusted or trimmed as necessary, keeping the mainsail at the best angle to capture the wind. The jib has two sheets that run down both sides of the boat.
