A sail plan is a drawing of a sailing craft, viewed from the side, depicting its sails, the spars that carry them and some of the rigging that supports the rig. [1] By extension, "sail plan" describes the arrangement of sails on a craft.
The standard 3.7 Class is used for class racing. A turbo version provides option to additionally fit a prod and gennaker. The 3.7 Class use a fully battened mainsail of approximately 8.8m^2 on a carbon mast. The sail plan is closely controlled by the class rules and the hull form is very closely controlled by the rules and measured on a jig.
The oldest sailing directions, dating back to the middle ages, descended directly from the Greek and Roman periplii: in classical times, in the absence of real nautical charts, navigation was carried out using books that described the coast, not necessarily intended for navigation, but more often consisting of reports of previous voyages, or celebrations of the deeds of leaders or rulers.

A lug sail is an asymmetric quadrilateral sail suspended on a spar and hoisted up the mast as a fore-and-aft sail. A mizzen sail is a small triangular or quadrilateral sail at the stern of a boat. A steadying sail is a mizzen sail on motor vessels such as old-fashioned drifters and navy ships (such as HMS Prince Albert ).
The sail plan of the Searunner 31 typically includes a main sail, jib, and sometimes a spinnaker. The trimaran configuration allows for efficient sailing in a wide range of wind conditions, with the ability to achieve higher speeds than monohull designs. One of the notable characteristics of the Searunner 31 is its folding mechanism.

Filled with wind, the sail has a roughly spherical polygon shape and if the shape is stable, then the location of centre of effort is stable. On sailing craft with multiple sails, the position of centre of effort varies with the sail plan. Sail trim or airfoil profile, boat trim and point of sail also affect CE.
