Mast (sailing)

	Wikinfo \| Sail
		On a sailing boat, a keel or centreboard is used as leverage to convert this lateral force into forward movement of the boat with some sideways leaning, or 'heel'.
		Sails are primarily used at sea, on sailing ships as a locomotive system, but have been rendered commercially obsolete by other forms of propulsion, such as the steam engine.
		Modern sails are designed such that the warp and the weft of the sailcloth are oriented parallel to the luff and foot of the sail.

	Sail Design and Construction
		The sail is constructed of a shaped membrane, usually of mylar film but it can be of films with light weight woven taffetas on the outer sides for extra durability, supported by yarns laid on top that curve throughout the sail to follow the load paths in the sail.
		The yarn density throughout the sail is varied to match the load requirements in different parts of the sail.
		The lower film membrane of the sail is laid out flat on their construction floor and a computer driven overhead gantry system lays out the continuous yarn matrix on the film.

	Sailing: From Work To Fun
		Sailing began many thousands of years ago, when some innovative primitive held up a skin to catch the wind and found that he could escape in this way the labour of paddling whenever the wind was fair.
		The amount of curvature in a sail is called the draft, and the perpendicular measurement from the chord to the point of maximum draft is called chord depth.
		Because a sail's curvature will always cause the aft end of the sail to be at a greater angle to the wind than the leading edge, the air at the leech is unable to follow the curve and returns its direction to that of the surrounding free air.

	Parts of a sail - Wikipedia, the free encyclopedia
		In sailing the parts of a sail have common terminology.
		In a triangular sail, the upper point is known as the head; the halyard, the line which raises the sail, is attached to the head.
		In a sail with a boom (such as a mainsail on a sloop), the clew is attached to the boom, and can often be tightened along the boom using the outhaul to adjust the sail shape.

	Sail Ship Sails
		In modern times a sail is cut of the extreme size which is capable of being carried in fine weather, and when the wind increases in strength it is reefed -- part is gathered up and fastened by reef points, small cords attached to the sail.
		Each mast has three parts, the lower mast, top mast and top gallant mast (three yards in which to hang sails.) The bowsprit is the spar jutting from the front of this ship in which sails and is also used to support the mast with stays, or support lines.
		Outboard of the square sails might be set studdingsails [studding sail, studsail, stun's'l) -- a sail on a special spar, extended outboard of a square sail or sails, for added sail area in moderate winds.

	reffing
		Slab reefing, also known as "jiffy reefing," is a process of temporarily removing sail area from the main by lowering the halyard and re-fastening the boom to the sail using reinforcements sewn to the sail at the reef tack and reef clew.
		When considering a reef, the strongest parts of the sail are the headboard, the reef clew, and the reef tack.
		The weaker parts of the sail are the luff sliders, and the spur grommets which are used to fasten the sliders to the luff of the sail, as well as the interim reef points used for tying the reefed portion of the sail around the boom.

	Sail - Wikipedia, the free encyclopedia
		Sails were invented in the ancient age, and was the most important source of propulsion during the age of sail.
		In order for a sail to be "built", it has to be designed in a number of elements (or panels) which are cut and sewn together to form the foil.
		The result is a smooth sail which is lighter and has a wider effective wind range (the minimum and maximum wind speed that the sail can withstand and be effective).

	Gaff Rig Detail Pages - The Main Sail
		To recap that information, the luff is that vertical portion of the sail that is nearest the mast, and the leech is the vertical portion farthest away from the mast.
		The foot on my sail plan is 127", while Leather's formula would put it smaller at 120" (the luff of 118" x the factor of 1.02 equals 120".) Fair enough, so far: the designers of the Weekender have a slightly longer foot, and a head that is just 2/3 of the size Leather recommends.
		Mast hoops are often used to attach the gaff sail to the mast, tied to the sail with "small stuff" (light line) as shown on the left.

		This is a true, aerodynamic, shaped sail, which means it is cut and sewn to have the necessary camber (3-dimensional curvature) for creating aerodynamic lift.
		But sometimes, when sailing, or in very rough conditions, you are frequently leaning and moving at the same time and can't keep the floats out of the water.
		If you sail or motor with foam floats pressed hard on the water and moving fast in the water, the foam floats may eventually develop some play between the float and the vertical tube it is mounted on.
