	The Sprit topmast backstay
		As long as a sprit topmast was carried, it was necessary to support this aft, and the sprit topmast backstay served this purpose.
		The sprit topmast backstay was attached to the sprit topmast crosstress with a short seized or spliced eye, and ran from there aft between the trestletrees.
		As with the fore topmast stay drawings, the illustrations on the facing page are intended primarily to give you the chance to check your plans for accuracy, and if necessary to correct them, as this is another case where some plan makers draw in the first arrangement they come across without thinking twice.

	Text-Book of Seamanship - Part 3
		Topmast Studding-sail-boom Braces may be either single, going over the boom-end with a running-eye and leading through a tail-block on the forward swifter of the main rigging; or double, with a pendant and whip leading to the main rigging.
		Topmast Studding-Sail Halliards are rove on each side through a single block hooked to the topmast cap; thence abaft the topsail-yard, through the jewel-block, and so to the deck, where they are attached to the central part of the studding-sail yard with a fisherman's or studding-sail halliard-bend.
		That for the topmast studding-sail is bent to the outer end of the yardarm and rove thence through a thimble on the leech, to the down-haul block at the tack, leading on deck, forward of the foresail, across the forecastle to the opposite side.

	Boy's Manual Of Seamanship And Gunnery
		When the topmast is about 3 ft. through the fid-hole, slew it one square forward, then lash the cap to it with two pieces of rope, clove-hitched round the topmast-head, and through the eye-bolts in the cap, one forward and one aft each side, for the cap to go up square.
		There are two plans for sending topmast rigging over the topmast-head, either by, putting a gantline and two man-ropes on the after part of the topmast-head, or by placing two gantlines on the after part of the tressletrees, and the man-ropes on opposite sides of the topmast-head.
		A topmast necklace is merely a chain-strop, the fore having two open links or legs on each side fox the hanging or topsail tye-blocks, jib and fore topmast staysail halyard-blocks and the main and mizen, one open link or leg each side for the topsail-tye, or hanging-blocks.

	* Topmast - (Boating): Definition
		Topmast - a second spar carried at the top of the fore or main mast, used to fly more sail.
		A topmast slides through two iron caps on the foreside of the mast.
		It is hauled up by the heel rope, which is fastened to the heel of the spar and passes through a sheave hole at the masthead.

	"Wavertree" Restoration Research
		It is suggested that the two portions of the topmast be retained as a measuring reference for the new spar.
		The fore topmast stay was originally pinned to the gammon band and is presently secured to the ship with a wire strap and two rigging screws.
		As well as may be determined, the mainstay and main topmast stay were secured to the deck, in the vicinity of the foremast partners, through riveted pads to the iron deck plate.

	Bowsprit, sprit topmast, jib boom
		From the early 16th century until about 1650 (occasionally as late as 1670), the bowsprit was routed past the foremast on the starboard side.It did not lie parallel to the keel, but at an angle, so that the head of the bowsprit was on the centreline of the ship.
		The split topmast itself was similar to a topgallant mast, but without a sheave for the topmast tye.
		The stays and topmast backstays exert a powerful pull on the split topmast when the rigging is set up, and it must not bend back further than the vertical.

	Pirates of the Burning Sea Community Website - Encyclopedia
		During the course of the 17th century the topmasts grew longer, the topsails grew ever larger, and the topgallant masts and topgallant sails were added; by then the topmast and topgallant shrouds were no longer capable of providing adequate support.
		The bacstays were shipped round the topinast head above the topmast shrouds in exactly the same way as the topmast shrouds, and from the first half of the 18th century it became usual to serve many of them over their ful length.
		Standing backstays were attached with deadeyes (they were the same size as the topmast shroud deadeyes), blocks (the running part of which was made fast above the upper block, as with the deadeyes), thimbles or rigging screws.

	Notes on Warrior Rigging 1860-1997
		Fore and main topmasts were 65 feet, topgallants and royals 53 feet wile the mizzen equivalents were 50 and 39 feet.
		Warrior's lower shrouds (nine each side) improved the angle of support, similarly the topmast shrouds were spread by the width of the topmast crosstrees.
		Lower mast, topmast and topgallant shrouds and stays were of iron wire, as was the royal mast stay, all other standing rigging being of tarred hemp.

	topmast \| English \| Dictionary & Translation by Babylon
		The topmast is one of these.The topmast is semi-permanently attached to the upper front of the lower mast, at the top.
		Its shrouds run to the edges of the top, rather than to the sides of the Hull, though long shrouds leading well aft to the hull, more in the manner of backstays, are sometimes seen.
		In the late 19th century, however, topsails became so big that merchant ships began to divide them into two separate sails for easier handling; since these were still on the topmast they were known as upper and lower topsails to preserve the consistency of the naming scheme.

	Tasar Topmast Stiffener
		Tasar class rule F.1.2 requires that all topmasts shall be fitted with a stiffener.
		The stiffener consists of two pieces of 6 mm 6061-T6 aluminum bar (or similar), inserted in the lower end of the topmast.
		Both are cut with the sides sloped by 10 degrees, so that they are a push fit inside the topmast section.

		The jib-boom, which is movable and projects beyond the bowsprit, corresponds to a topmast; the flying jib-boom, which also is movable and projects beyond the jib-boom, answers to a topgallant mast.
		Near the heads of the lower masts are the tops—platforms on which men can stand—and in the same place on the topmasts are the “crosstrees,” of which the main function is to extend the topgallant shrouds.
		Pressure from behind is met by the backstays, which connect the topmasts and topgallant masts with the sides of the vessel.

	Thames Sailing Barges - Glossary
		On a barge the topmast shrouds are sometimes known as "standing backstays" and the topmast backstays as "topmast running backstays".
		The bargeman's spinnaker is his topmast staysail tacked at the mast case, and sheeted round the weather cross-tree.
		A light, undressed, triangular sail of flax canvas or cotton, which may be set in three ways; from the bowsprit to the topmast head over the jib, from the stem head to topmast over the foresail, and as a spinnaker for running before the wind.

	Dinghy Topmast Welding Techniques
		The amount of material put into the weld, and therefore left inside the mast as a filet, was totally dependent on the operator and was therefore subject to variation.
		The extrusion is slid into the gap, and the welding machine passes down the tube in one pass, melting the extrusion and leaving a uniform filet down the outside of the mast.
		Any variations were found to be due to a natural variation in tube thickness as the die wears in time and is eventually replaced, not a difference in characteristic of topmast only.

	Ship Modeling FAQ, Research Note Sail Confusion --- Revised: June 13, 2005
		The square sail hung from that second mast was called a topsail -- fore topsail, main topsail, mizzen topsail, etc. By the end of the 1600s the topsails had grown so large that they were the main driving sails of a square rigger.
		So, something like the Flying Cloud would have four masts: a lower mast with a upper and lower course, a topmast with an upper and lower topsail, a topgallant mast with a topgallant sail, and a royal mast with a royal sail.
		The lower part of the lowest mast would be called the lower mast, with the upper part being the topmast -- or even the topmast and the topgallant (assuming you had a one-piece mast).

	The Square Rigging
		The topmast is supported by the topmast stay (blue) and topmast shrouds (red) that go from the top of the topmast down to the outer edge of the top.
		One pair is fastened at the same place as the topmast stay, and the other pair is at the absolute top of the topmast.
		On the topmast is the topsail, often divided into the lower topsail and the upper topsail.

	Alberta's mast head
		The topmast forestay (top right) has a topmast halyard block with becket inserted in-line which gives a fair lead to the head of the 3000 sq.ft. spinnaker.
		Below right is the tops'l halyard block which is another change from convention, usually a sheave is let into the topmast and the fall comes out on the forward side of the topmast (another classic place for rot).
		Conventionally, only the topmast has running backstays (bottom wires) but the keen smack racers have added running backstays to the main mast head as well in the drive to keep a tight luff on the jib.

	Arriving Topless in Cartagena
		The main blocked our view, but what was alarmingly apparent was that the topmast had somehow fallen forward of the mainmast, the top with the navigation light (still working) now dangling bow-wards almost touching the foredeck.
		"The topmast has fallen over the starboard side and is in the water, and the spreader is swinging around the mainmast and the port shrouds.
		Between holding on for dear life as the starboard beam rolled towards the waves, and hauling in the shrouds as it rolled skywards again, Alfred was finally able to lash the topmast onto the outside of the rails, literally being awash throughout the process by wave after wave.

		The 2 main shrouds each side obviously cant in from the chains to the mast, but the topmast shroud rises from the same point but only inclines slightly on its way to the cross-trees.
		The alternatives seem to be either putting the screen high up, at the point where the topmast shroud would just touch the outer edge of the screen.
		The other would be having a hole in the base of the screen for the topmast shroud to pass through - big enough to take the eye.

		XV.- If the fleet is sailing by a wind in a line of battle, and the admiral would have them brace their headsails to the mast, he will hoist a yellow flag on the flagstaff at the mizen topmast- head, and fire a gun, which the flagships in the fleet are to answer.
		XXIX.- If the admiral would have any flag in his division or squadron cut or slip in the daytime, he will make the same signals that are appointed for those flagships, and their division or squadron, to tack and weather the enemy, as is expressed in the third, fourth, fifth, and sixth articles before going.
		If he would have the white squadron or those that have the second post in the fleet, to do the like, the signal shall be a flag striped red, white, and blue, with a pennant under it, at the aforesaid place.
