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. [2] [3] A sailing craft may be waterborne (a ship or boat), an iceboat, or a sail-powered land vehicle.

Sail plan of a sloop. Each rig may be described with a sail plan—a drawing of a vessel, viewed from the side, depicting its sails, the spars that carry them and some of the rigging that supports the rig. [4] By extension, "sail plan" describes the arrangement of sails on a vessel.
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.
In the rare case, the cross-jack yard did carry a square sail, that sail would be called the cross-jack rather than the mizzen course. The full set of sails, in order from bottom to top, are: Course sail; Topsail, or Lower topsail, if fitted. Upper topsail, if fitted. Topgallant sail, or Lower topgallant sail, if fitted. Upper topgallant sail ...
On nautical charts, the top of the chart is always true north, rather than magnetic north, towards which a compass points. Most charts include a compass rose depicting the variation between magnetic and true north. However, the use of the Mercator projection has drawbacks. This projection shows the lines of longitude as parallel.
The sail plan consists of a Bermuda rig with a main, jib, and symmetrical spinnaker. The boat uses a retractable centreboard. An optional asymmetric spinnaker and spinnaker chute is available; also available is a "sail patch" which provides flotation for the mast in the event of a capsize (and particularly to prevent mast inversion – Turtling ...
Literally, the word pinisi refers to a type of rigging (the configuration of masts, sails and ropes ('lines')) of Indonesian sailing vessels.A pinisi carries seven to eight sails on two masts, arranged like a gaff-ketch with what is called 'standing gaffs' — i.e., unlike most Western ships using such a rig, the two main sails are not opened by raising the spars they are attached to, but the ...
