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.
For a triangular sail the head refers to the topmost corner. [37] A fore-and-aft triangular mainsail achieves a better approximation of a wing form by extending the leech aft, beyond the line between the head and clew on an arc called the roach, rather than having a triangular shape.
AAW An acronym for anti-aircraft warfare. aback (of a sail) Filled by the wind on the opposite side to the one normally used to move the vessel forward.On a square-rigged ship, any of the square sails can be braced round to be aback, the purpose of which may be to reduce speed (such as when a ship-of-the-line is keeping station with others), to heave to, or to assist moving the ship's head ...
A mainsail ("mains'l") is a sail attached to the main mast. The principal types include: A square-rig mainsail is a square sail attached at the bottom of the main mast. A Bermuda-rig mainsail is a triangular sail with the luff attached to the mast with the foot or lower edge generally attached to a boom.
A broker price opinion (BPO) is a real estate professional’s dollar estimate of a property’s worth. It is an opinion, but one often backed up by the selling prices of comparable homes in ...
This meant a traditional mainsail could be raised no higher than the first point a rope or wire was required to keep the mast upright. Further mainsail area (and height) was obtained by adopting a gaff rig. A mainsail may be fixed to the boom via slugs, cars, or a bolt-rope, or may be "loose-footed," meaning it is only attached at the tack and ...
A lateen (from French latine, meaning "Latin" [1]) or latin-rig is a triangular sail set on a long yard mounted at an angle on the mast, and running in a fore-and-aft direction. The settee can be considered to be an associated type of the same overall category of sail. [2]
A trysail (also known as a spencer [citation needed]) is a small triangular or gaff rigged sail hoisted in place of a larger mainsail when winds are very high. [1] The trysail provides enough thrust to maintain control of the ship, e.g. to avoid ship damage, and to keep the bow to the wind.
