A sailing vessel, a mast, a sail, a line, a yard…
On board a ship, the yard is a spar belonging to the wider family of rigging components, which includes wires, ropes, head fittings, blocks and sails.
On a sailing yacht or ship, a yard is an elongated structural element used to support a sail. Traditionally made of wood—often spruce due to its lightness—it may also be constructed from modern materials. A yard can be fixed, supported against the mast, or pivoting (via a parrel or similar fitting).
Originally cylindrical in shape, the yard is primarily associated with square rigging, where it supports a sail set perpendicular to, and forward of, the mast.
Yards in square-rigged vessels
On square-rigged ships, yards are named according to the sails they carry and/or the masts to which they are attached. For example:
- the fore topsail yard is fitted to the foremast,
- the main topsail yard to the main mast,
- the mizzen topgallant yard to the mizzen mast.
Today, such large square-rigged vessels are rarely constructed, though they remain emblematic of traditional seamanship.
Extension of the term “yard” across rig types
In contemporary usage, the concept of a yard extends to various sail configurations, although the terminology varies depending on the rig:
- for a spritsail, the spar is referred to as a sprit;
- for a gaff sail, it is called a gaff;
- for a lateen sail, it is known as a lateen yard (antenna).
Relationship between the sail and its yard
The relationship between a sail and its yard is fundamentally one of support. However, their orientation varies depending on the rig.
- Gaff sail: a four-sided sail commonly used on cutters, sloops, brigantines and schooners. It is set on a relatively short yard (gaff), with its luff laced to the mast. The Houari variant features a yard set at a very slight angle, almost appearing as a continuation of the mast.
- Lug sail: a quadrilateral sail whose yard is hoisted approximately one-third up the mast. It is typically attached using a traveller or parrel, allowing limited control during hoisting and lowering.
- Lateen sail: a triangular sail common in Mediterranean regions, set on a long yard (antenna) positioned obliquely. The halyard is attached at roughly two-fifths of the yard’s length.
- Spritsail: unlike square sails, it is not “set on” a yard in the strict sense; instead, a diagonal spar (sprit) supports the peak of the sail.
- Square sail: square or rectangular in shape, set on a yard positioned perpendicular to the mast and supported at its midpoint. Historically, most naval and merchant vessels were square-rigged.
- Topmast studding sail (staysail / topsail extension): set on an additional yard to increase sail area.
The yard in sailing manoeuvres
On board, the yard interacts closely with other spars and rigging elements. It plays a central role in sail handling:
- Halyard: used to hoist or lower both yard and sail;
- Braces: control the angle of a square sail by rotating the yard;
- Clewlines and buntlines: gather the sail towards the yard when furling.
Key manoeuvres involving the yard
Hoisting a sail
Once the sail is clear and the halyard secured to the yard (via a parrel or collar), the crew hoists both sail and yard.
To hoist “home” means to hoist fully to the top of the mast by fully tensioning the halyard.
Furling a sail
After gathering the sail using appropriate lines, it is neatly stowed by folding it along the yard and securing it with reef points or gaskets.
Peaking a gaff sail
The peak halyard raises the outer end of the gaff, ensuring proper sail shape and setting.
Gybing a yard (wearing ship / shifting the yard)
This manoeuvre moves the yard from one side of the mast to the other, positioning the sail to leeward. It is typically used with large fore-and-aft sails such as lateen or lug sails.
Lacing (seizing) a sail to a yard
Using a line, the sail is secured to the yard through its eyelets in a continuous lacing pattern.
Reefing
Reefing reduces sail area in strong winds.
- On square and lateen sails, reefs are taken along the upper part of the sail near the yard, and the yard is lowered accordingly.
- On Bermudan rigs, reefing is generally vertical along the mast.
To prevent excessive tension, a yard tackle (lifting purchase) may be used to support the lower অংশ of the sail during reefing operations.
