Description
ORC uses the International Measurement System (IMS), a set of rules defining what and how it is measured on the boat. The IMS uses the Equipment Rules of Sailing (ERS) nomenclature and definitions published every four years by World Sailing (WS), which is the world governing body for the sport of sailing, officially recognized by the International Olympic Committee (IOC).
The ERS defines a sail as an item or equipment used to propel a boat. It defines three types of trilateral sails:
– Mainsail, which also applies to foremast sail and mizzen.
– Headsail, which also applies to “jib” and “genoa“.
– Spinnaker, which also applies to “gennaker“.
Mainsails are sails with the luff attached to the mainmast. The ERS defines the mainmast as:
– The only mast in a una rig, sloop rig, or cutter rig.
– The fore mast in a ketch rig or yawl rig.
– The aft mast in a schooner rig.
Headsails are sails set forward of the mast, or of the foremast mast if there is more than one mast, where the measurement between the half luff point and the half leech point is less than 75% of the foot length. Additionally, the distance between the half foot point and the half luff point shall be not greater than 55% of the luff length (HLU). Headsails may be set on the forestay or set flying. The IMS defines a sail Set Flying as a sail set with no sail edge attached to the forestay.
Spinnakers are sails set forward of the mast, or of the foremast mast if there is more than one mast, where the measurement between the half luff point and the half leech point is equal or greater than 75% of the foot length. There are two types:
– Symmetric: it is symmetric in shape, material, and cut, about a line joining the head to the center of the foot.
– Asymmetric: any spinnaker not qualifying as symmetric.
