Running Rigging of A Square-rigged Ship

A square rigged ship requires much more running rigging, and therefore much larger crews than a modern sailboat

• Bowlines run from the leech (outer vertical edges) of a sail forward (towards the bow) and are used to control the weather leech, keeping it taut and thus preventing it from curling back on itself. To extend its spread it was often attached to a bridle and thence to three or four bowline cringles set upon the leech.
• Braces, are used to adjust the fore and aft angle of a yard (i.e. to rotate the yard laterally, fore and aft, around the mast).
• Brails run from the leech of a fore-and-aft rigged sail (a spanker or lateen mizzen, for example) to the gaff and mast and serve the same function as buntlines: to haul in the sail when furling. In this case, however, the action is more horizontal than vertical, hauling the sail forwards, toward the luff and a bit up, towards the gaff.
• Buntlines, spaced every few feet along the front of a sail, run from a point on the mast above the yard to the foot (bottom edge) of the sail and serve to raise the foot up for shortening sail or for furling.
• Clewlines raise the clews (bottom corners) of a square sail to the yard above, either to the outer ends of a yard or, more commonly, to near the middle of the yard, near (but not quite at) the mast. As the clewlines were hauled in, the sheets would be slacked off. This process would be reversed when setting sail. Note that the clewline from the course (main sail) was called the Clewgarnet.
• Halyards (sometimes haulyards), are used to raise and lower the yards (and thus their name: they are the ropes on which you haul to raise the yard).
• Leechlines run to the leech (outer vertical edges) of a sail and serve to pull the leech both in and up when furling.
• Lifts, adjust the tilt of a yard, to raise or lower the ends off the horizontal.
• Sheets, attach to the clews (bottom corners) of a sail to control the sail's angle to the wind. Sheets run aft (for comparison, see tacks).
• Tacks, are used to haul the clew of a square sail forward. Tacks run forward (for comparison, see sheets).
