In sailing vessels, the head is the ship's toilet. The name derives from sailing ships in which the toilet area for the regular sailors was placed at the head or bow of the vessel. Design
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.
A masthead rig on a sailing vessel consists of a forestay and backstay both attached at the top of the mast. [1] The Bermuda rig can be split into two groups: the masthead rig and the fractional rig. The masthead rig has larger and more headsails, and a smaller mainsail, compared to the fractional rig.
Military vessels. Corvette: lightly armed, fast sailing vessel; Cutter: small naval vessel, fore-and-aft rigged, single mast with two headsails; Frigate: a ship-rigged warship with a single gundeck; Ship of the line: the largest warship in European navies, ship-rigged; Xebec: a Mediterranean warship adapted from a galley, with three lateen ...
A sail batten is a flexible insert in a fore-and-aft sail that provides added stiffness and definition to the sail's airfoil cross-section. [1] The most common use of sail battens is in the roach of a mainsail. The batten extends the leech past the line that runs from the head and the clew of the sail to create a wider sail towards the top.
In early designs the solution to engineering problems was frequently: just add more fiberglass. The early boats were sturdy but heavy. Many of the vessels produced during this time frame are afloat today, and several models still enjoy solid sales demand and exhibit excellent sailing characteristics.
Corners: 1 – Head 10 – Tack 12 – Clew SC70 RETRO's genoa overlaps the main sail and the mast. A genoa sail is a type of large jib or staysail that extends past the mast and so overlaps the main sail when viewed from the side, [1] sometimes eliminating it. It was originally called an "overlapping jib" and later a genoa jib.
Lift on a sail (L), acting as an airfoil, occurs in a direction perpendicular to the incident airstream (the apparent wind velocity, V A, for the head sail) and is a result of pressure differences between the windward and leeward surfaces and depends on angle of attack, sail shape, air density, and speed of the apparent wind.
