In [[sailing]], a '''spar''' is a round pole of [[timber|wood]], [[metal]] or lightweight materials such as [[carbon fiber]] used on a [[sailing ship]]. Spars of all types (e.g. [[booms]] and [[guyed mast]]s) are used in the [[rigging]] of sailing vessels to resist [[compressive stress|compressive]] and [[bending]] forces, and to provide (direct or indirect) support for the [[sail]]s.

Wooden ships from the [[age of sail]] often carried many extra spars of all types for repairs while at [[sea]]. The spar deck of a [[frigate]] was so named because it was used to carry spare spars.

A spar is a pole of wood, metal or lightweight materials such as carbon fibre used in the rigging of a sailing vessel to carry or support its sail. These include yards, booms, and masts, which serve both to deploy sail and resist compressive and bending forces, as well as the bowsprit and spinnaker pole.

In larger vessels during the age of sail, spare spars could be roped together to provide a temporary surface known as a "spar deck". These served as jury-rigged repairs for permanent decks, or as an additional platform under which to shelter goods or crew. The term was also informally applied to areas of the forecastle or quarterdeck where spare spars were stored by laying them flat against the existing decking. In the modern era the term has been used to describe the uppermost deck on flush decked vessels.[1]
