Sail plan of a brig. 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 ...
Each rig is configured in a sail plan, appropriate to the size of the sailing craft. Both square-rigged and fore-and-aft rigged vessels have been built with a wide range of configurations for single and multiple masts. [65] Types of sail that can be part of a sail plan can be broadly classed by how they are attached to the sailing craft:
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 ).
The hull shape and sail plan are tightly controlled, while the spars, foils and rigging are more open which allows the boat's rig and controls to be set up to the preferences of the crew, rather than dictated by the class rules. [citation needed]
An improved design sporting a sailing canoe sail rig did however strike a spark as a possible profit making venture. From that humble beginning the Sailfish was born. After Bryan's wife, Aileen Bryan, suggested a boat with a small cockpit where she could put her feet, the design was updated to the Sunfish. [10] [11] Sunfish (wooden; 1953)
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.

Put the mast back on the correct side of the sail! 02:06, 20 April 2017: 512 × 531 (6 KB) HLHJ: Moved akas and amas so that the centers of effort looked as if they would line up, stepped the mast in the middle of the boat as seen in File:Proa1.jpg and File:Südseeabteilung in Ethnological Museum Berlin 137.JPG.
