Upffront.com is all about performance sailing hardware and rigging systems. The heart, and driving force, of any sailing yacht is its mast and standing rigging which support the sails. If you are interested in optimising / upgrading your sailing systems it is important for us to have a common language, so we can share performance improvement ideas and options. In this blog we outline the key terminology of modern masts and rigging.
The standing rigging is the fixed / structural stays which support the mast. These are often split into Fore & aft (forestay and backstay) and then the lateral rigging (side shrouds). In wire rigging world, people often refer to the Cap shroud (running all the way from deck to masthead) and intermediate stays, however when we start talking rod and composite rigging we need to be more explicit and break the lateral rigging elements down in more detail.
Standing rigging attachment points on the mast are called Tangs. There are many different types of tangs and when working on rigging projects it is critical to know what you are dealing with. For example. a forestay tang can be a single plate (Lug), which requires a fork interface, or two plates on the rig (Jaw), designed for an eye fitting. Pin hole diameters, plate thicknesses and overall geometry are all crucial measurements when working with these types of tangs.
Masts move......... and articulation is an essential element of any structural rigging joint. The reason stemballs are so popular is that they are essentially a ball joint which allows articulation. For any other mast or deck attachment a Toggle is used to allow articulation in two planes.
A damaged wire can turn a leisure boat ride into a very dangerous one, very fast. A broken wire can bring the mast down without the need for winds to do so. All it takes is a combination of several factors: rigging, and weather conditions, and the right, or wrong, maneuver.

The Skipper's Mast and Rigging Guide is a new title in our popular series of laminated cockpit guides that are designed for easy reference on board in all weather conditions.Of all the elements that are hard to set up on a sailboat, gauging how mast, running rigging and standing rigging should work in combination with each other is perhaps the trickiest of arts - some might call it a black art. And of course it is essential to get it right in order to stabilise the mast, reduce undue stress and consequently ensure the safety of everyone on board.This handy cockpit guide will simplify and explain to the reader exactly how to set up their mast, rigging and running rigging for whatever size of yacht and with whatever rig combination.It will take the reader through the basics of setting up and adjusting their rig step by step with helpful diagrams and detailed colour photographs throughout. With this book in one hand and a spanner in the other, skippers will be able to make their own adjustments without having to call in expensive professional riggers.

Continuous rigging, common in production sailboats, means that each shroud (except the lowers) is a continuous piece of material that connects to the mast at some point, passes through the spreaders without terminating, and continues to the deck. There may be a number of continuous shrouds on your boat (see Figure 1).
Discontinuous rigging, common on high performance sailboats, is a series of shorter lengths that terminate in tip cups at each spreader. The diameter of the wire/rod can be reduced in the upper sections where loads are lighter, reducing overall weight. These independent sections are referred to as V# and D# (see Figure 2). For example, V1 is the lowest vertical shroud that extends from the deck to the outer tip of the first spreader. D1 is the lowest diagonal shroud that extends from the deck to the mast at the base of the first spreader. The highest section that extends from the upper spreader to the mast head may be labeled either V# or D#.
MASTS are made of long fir-trees cylindrically rounded: their sides, curving lengthways, form an arch of an ellipsis, resembling the shaft of a column, elevated perpendicularly upon the keelson, to which are attached the yards, sails, and rigging.
SHEER-HULK, which is used in the royal navy for masting of vessels, is an old ship of war, cut down to the gun or lower deck, with a mast fixed in midships, about 33 inches diameter, and 108 feet high, strengthened with shores; the upper shore 87 and the lower shore 81 feet long, and each 19 inches diameter. There are shrouds and stays to secure the mast and sheers, which act as the arm of a crane, (supported by a derrick, 100 feet long and 22 inches diameter,) to hoist in or out the lower masts, when conveniently laid alongside.
SHEERS, used for masting vessels in the merchant service, are two hand-masts or large spars, erected on the vessel whose masts are to be fixed or displaced; the lower ends or heels rest, on opposite sides of the deck, upon thick planks sufficiently long to extend over two or three beams shored underneath. The two handmasts cross each other at the upper end, and are securely lashed. A tackle is lashed in the centre, and hangs perpendicularly over the station where the mast is to be fixed.
The saddle for the running-rigging is similar to the above, and nails on the bowsprit just without the gammoning, but not till the bowsprit is rigged. It has several holes bored through fore and aft, through which the rigging is led clear into the bow.CLEATS are made for stops against the collars and gammoning, and are nailed on when rigging. The cleats against the collars to be in length one-half the given diameter; and one-fourth the length thick and broad. The cleats against the gammoning to be two inches shorter than the collar cleats, and the same in proportion. The ends are cut bevelling to the direction of the rope.Lastly, a woolding, the same as on the mast, is fixed just within the square at the outer end.The bowsprits of small vessels, as cutters, &c. commonly have an iron hoop set on, which nails to the outer end; with an eye on each side, and one in the middle, on the upperside, and a sheave-hole cut through the inner and outer ends.
Yards are fitted at their outer ends for rigging out studding-sails. Main and fore yards have four boom-irons; one on each of the outer ends, the others at one-third the length of the boom within. The outer boom iron is composed of a ring, a neck, and straps.
Mast and topmast in one, thrice and 3/4 the breadth of the vessel.Mast to the rigging-stop or hounds 3/4 the whole length.Mast and topmast to the stop of the topmast 40/41 of the whole length.Topgallant-mast to the rigging-stop 4/7 of the length of the mast.
In general, any situation requiring a redesign, whether total or partial, we feel should be done only after consulting with professionals. This includes any situations involving change of materials or geometry. For example if we were going from rod to wire rigging, or from wire to HMPE (High Modulus Polyethylene e.g. dyneema), we would consult professionals. Likewise if we were replacing a mast or spreaders we would involve professionals because these situations create different loads on the rigging and therefore may require resizing the wire or attachment points. And of course if you have any reason to feel that the current rig is not adequate you do not want to repeat those mistakes in the new rig and you will also need a redesign. Get a professional involved in these cases. 59ce067264
