Sail components include the features that define a sail's shape and function, plus its constituent parts from which it is manufactured. A sail may be classified in a variety of ways, including by its orientation to the vessel (e.g. fore-and-aft) and its shape, (e.g. (a)symmetrical, triangular, quadrilateral, etc.).
For a triangular sail the head refers to the topmost corner. [37] A fore-and-aft triangular mainsail achieves a better approximation of a wing form by extending the leech aft, beyond the line between the head and clew on an arc called the roach, rather than having a triangular shape.
A square-rig mainsail is a square sail attached at the bottom of the main mast. A Bermuda-rig mainsail is a triangular sail with the luff attached to the mast with the foot or lower edge generally attached to a boom. A gaff-rig mainsail is a quadrilateral sail whose head is supported by a gaff.

Dhow with lateen sail in "bad tack" with the sail pressing against the mast, in Mozambique. The emergence of new evidence for the development and spread of the lateen sail in the ancient Mediterranean in recent decades has led to a reevaluation of the role of Arab seafaring in the Indian Ocean, replacing a belief that this sail has an eastern origin.
Sails are classified as "triangular sails", "quadrilateral fore-and-aft sails" (gaff-rigged, etc.), and "square sails". [38] The top of a triangular sail, the head , is raised by a halyard , The forward lower corner of the sail, the tack , is shackled to a fixed point on the boat in a manner to allow pivoting about that point—either on a mast ...
Sails set beyond the peak were typically called jibs, set on stays running from the fore topmast to the bowsprit, or the fore topgallant mast to the jibboom or even the fore royal mast to the flying jibboom. A large square-rigged ship typically has four jibs, but could have as many as six. [3] [4] From forward to aft, these sails are called ...
