	* Mainsail - (Boating): Definition
		Mainsail: The principal sail of a sailing vessel.
		The mainsail is prepared for raising by attaching its tack at the gooseneck and the clew at the outhaul as for a Laser.
		The side opposite to that on which the mainsail is carried or, in the case of a square-rigged vessel, the side opposite to that on which the largest fore-and-aft sail is carried.

	Mainsail -- Facts, Info, and Encyclopedia article (Site not responding. Last check: 2007-10-21)
		A mainsail is the most important sail raised from the main (or only) (A vertical spar for supporting sails) mast of a sailing vessel.
		The modern (A rig of triangular sails for a yacht) bermuda rig uses a triangular mainsail as the only sail aft of the mast, closely coordinated with a (Any triangular fore-and-aft sail (set forward of the foremast)) jib for sailing upwind.
		Traditional fore-and-aft rigs used a (An iron hook with a handle; used for landing large fish) gaff to control the top of the mainsail, sometimes setting a (A sail (or either of a pair of sails) immediately above the lowermost sail of a mast and supported by a topmast) topsail above it.

	The Quest for the Perfect Shape
		Furthermore, for a given sail the shape varies from the foot to the top, and the fast shape of a mainsail is different from that of a jib which is different from that of a #1 genoa, not to mention a spinnaker.
		To understand sail shape it is useful to visualize the mainsail and the jib as a single "wing" (airfoil) with a slot in the middle.
		When the distance from the leech of the genoa to the mainsail is even all the way from the boom to the hounds, the slot is said to be even.

	ITCA- Mast Tuning
		Controlling mast bend is the first step towards controlling the mainsail, and controlling the mainsail allows us to fine tune the delicate balance between sails and keels.
		Mainsail luffs are cut with a curve that has to approximate the mast bend.
		The effect is that the mainsail is always sailing around in a slight header relative to the genoa.

	Sail Trim & Shape
		Once the mainsail is hoisted, loosen the boom toping lift so the mainsail can assume the proper shape and swing freely from side to side.
		In the second method, the boat is heaved-to and the mainsail is let out until it is luffing.
		Since the boom is out over the water, the mainsail is doused (taken straight down) and may be flaked after the boat reaches the dock or once the mast is secured back to midline.

	Cruising World - A Mainsail for all Seasons
		The useful life span of a mainsail is largely dependent upon the strength and stability (ability to retain shape) of the sailcloth and its resistance to chafe and the sun’s ultraviolet rays.
		A mainsail’s reef rows typically are spaced relatively evenly and roughly parallel to the foot of the sail at a workable distance from any battens.
		A cruising mainsail is asked to perform on all points of sail, in almost all wind speeds, and in a challenging variety of sea states—and it’s expected to do so for many years across thousands of nautical miles.

		A rigid flat plate at the top of a sail (usually a mainsail), which serves as a reinforcement, an attachment point for the halyard, and an attachment point for the highest luff slider.
		The fittings on the luff of a mainsail which allow the sail to slide along a track or groove on the back edge of the mast.
		In a mainsail (or a jib), the sailcloth which extends aft of a straight line between the head and the clew.

	Mainsail Overview (Site not responding. Last check: 2007-10-21)
		MAINSAIL was originally developed at Stanford University under the auspices of the SUMEX Computer Project by the founders of XIDAK, Inc. It is an ALGOL-like programming language derived from the SAIL programming language.
		The entire MAINSAIL compiler and the bulk of the runtime system are written in MAINSAIL, minimizing the effort required by XIDAK to move MAINSAIL to a new processor or operating system.
		MAINSAIL is an extremely powerful programming language offering features not found in other popular programming languages such as C, Pascal, Modula-2, or Ada.

	Sail Shape
		Once the proper shape of the mainsail has been achieved, any changes in the tension of the boom vang or the mainsail's sheet will change the shape of the sail.
		The mainsail's sheet not only determines the position of the boom in relationship to the deck but also places a downward pull on the leech (aft or back edge) of the mainsail.
		One should note that when the backstay is tightened, the mainsail's sheet and boom vang may also have to be adjusted or the mainsail's shape will change.

		Slicing effortlessly to weather is a byproduct of a well-built, well-trimmed mainsail working in unison with the hull, keel, and headsail.
		All of this pure magic is made possible by a well-built, well-trimmed mainsail working with your keel to provide lift, and just the right headsail powering you forward.
		In the first four articles of this series we looked at the various fibers that are used to make sailcloth, how they are incorporated into different fabrics, and how the fabrics are used in different panel layouts to take full advantage of their best qualities.

		If the breeze increases significantly and you find that the boat is beginning to be overpowered, you can flatten the entry of the mainsail and move the draft forward by tensioning the luff with the cunningham.
		More than likely your mainsail will be too full for the new breeze, a condition that will overpower the boat and create excessive weather helm for the person driving.
		In this case, either have the driver briefly feather the boat up into the wind so the sail is less loaded, or have the mainsail trimmer briefly ease the mainsheet for the same effect, then you can tension the outhaul more easily.

	Sail Propulsion - Revisiting a Mast-Aft Sailing Rig
		A staysail was then rigged between the masts in place of the mainsail, and the boat regained 1 knot of speed while retaining its decreased leeway.
		I was looking to discard the inefficient mainsail, and replace it with two clean leading-edge headsails (ala cutter), acting in a parallel, harmonious fashion, and with no mast spreader overlap so they might be sheeted in for optimum pointing.
		The inner main-staysail will replace the Bermudian mainsail and perform a similar function in a more efficient manner, as its leading edge is not fouled by a mast and its foot not misformed by a boom.

		2) Increase the cunningham or mainsail halyard tension.
		Race mainsails are often constructed with a lens shaped panel of lighter weight fabric connecting the straight foot of the sail with the boom.
		Cruising mainsail reef locations are usualy positioned to take away larger chunks of sail area than most sailors are used to in general purpose mainsails.

	Basic Mainsail Trim for Racers, (Site not responding. Last check: 2007-10-21)
		The first time that I recall being asked to trim a mainsail was aboard a new 40-foot PHRF racer a few years back.
		But I had read plenty of articles about mainsail trim, and so, even though I had very little onboard experience with mains, I felt up to the task.
		As it turned out, all the mainsail articles I had read were like a bad course in sex education—they explained what it was, all of its parts, and the technical reasons for using them, but not when, how, or why to make these things work.

	Offshore Sails - About Mainsails
		These mainsails are the more traditional mainsail cut with short length battens and slab reefing.
		A more recent trend has been for mainsails to be designed with only the upper one or two battens being full length and the rest of the battens being shorter.
		In-mast roller furling mainsail systems have been extremely popular for their ease of handling (no need to flake the sail on the boom and reducing sail area and packing sail away can all be done from the cockpit), despite their reduced efficiency.
