The domain of rigging is an essential matter for the safety and good performance of your sailboat. Nowadays, the type of rigging is still evolving. Generally, rigging is depending on the type of sail used or the number of masts. As a basic rule, the replacement of the standing rig should be done every 10 years, except for multihulls or regattas, and rod or composite fiber rigging. A good set of rigging is of great importance in order to ensure navigation without causing any damage. A useful tip is to perform often thorough checks of the state of the rigging of your sailboat. Like this, you will prevent any possible damages from happening. So, let’s examine what exactly is sailboat rigging.

Standing and Running Rigging

Standing rigging supports your sailboat’s mast. The standing rigging consists of all the stainless steel wires that are used to support the mast. Moreover, standing rigging includes the rods, wires, and fixed lines that support the masts or bowsprit on a sailing vessel. In addition, all these reinforce the spars against wind loads transferred from the sails. On the other hand, running rigging is the rigging for controlling and shaping the sails on a sailboat. Running rigging consists of the main and jib sheet, the boom vang, the downhaul, and the jib halyard.

The subdivision of running rigging concerns the jeers, lifts, and halyards (halyards). This supporting equipment raises or lowers the sails and also controls the lower corners of the sails, i.e. the tacks and sheets. Over the centuries and up until nowadays, the history of sailboats rigging is still developing. What we’ve learned by now is that the combination of square and fore-and-aft sails in a full-rigged ship creates a highly complex, and mutually reliant set of components.

Wire Rigging

Wire rigging is the most common form of standing rigging on sailboats today. Furthermore, the style of the wire used is made of stainless steel, which is also a common wire style. What is advantageous with wire is that it’s quite affordable, especially when using swage fittings. The wire has also a long life expectancy, about 10 to 20 years, depending on use and the region you’re sailing to. However, wire rigging is more elastic than rod and synthetic rigging, thus it offers the lowest performance.

Rod Rigging

The rod rigging composition is of high-quality materials that provide low stretching. Moreover, it has a very long lifespan and great breaking strength, much more than that of its wire counterpart. Its life expectancy is attributed to the design, which is a mono strand, as well as to its composition that makes it very corrosion resistant.

Synthetic Rigging

Synthetic rigging is a new type of rigging and just like a rod, has minimum breaking strength. Nowadays, synthetic rigging offers low stretch performance features (that may vary depending on construction type), which are quite good for sailboats, among others. However, synthetic rigging will not last as long as the metal components. Most of the time, metal wire and rod are far better than synthetic rigging.

Rig Types

Based on the two rig types which are square-rigged and fore-and-aft, let’s divide the fore-and-aft rigs into three groups:

  • Lateen Rig has a three-sided mainsail on a long yard.
  • Bermuda rig which has a three-sided mainsail.
  • Gaff rig is the head of the mainsail and has a four-sided mainsail.

Parts of a Sailboat Rigging and Terminology

Cruising sailboats will usually have their mast supported by 1 x 19 stainless steel wire. However, there are some racing sailboats that may choose rod rigging. Why? That’s because rod rigging has a stretch coefficient that is some 20% less than wire. The downside is that it’s more difficult to install and adjust, as well as less flexible with a shorter life span. So, let’s move on and see the parts of the sailboat’s rigging and their terminology:

  1. Forestay and Backstay: Forestay and backstay support the mast fore and aft. The forestay keeps the mast from falling backward. It attaches at the top of the mast. The backstay is important for the sail’s control because it directly affects the headsail and mainsail.
  2. Cap Shrouds and Lower Shrouds: These parts hold the mast steady athwartship. The shrouds are attached to the masthead and via chainplates to the hull. Moreover, forward and aft lower shrouds provide further support. The lower shrouds are always connected to the mast, just under the first spreader, and at the other end to the hull.
  3. Spreaders: In general, spreaders keep the shrouds away from the mast. What is of high importance, in terms of stability, is their length and fore-and-aft angle. The rigs of cruising boats may have up to three pairs of spreaders, depending on a number of factors such as the sailboat’s size and type. Keep in mind that the more spreaders a sailboat has then the lighter the mast section can be. Last but not least, the spreaders must be robust in order to withstand the compression loads of the shrouds.
  4. Masts and Booms: Masts are tall spars that carry the sails, navigate the sailboat, and control its position. Sailboat booms are horizontal spars to which the foot of a sail is bent. The booms attach to the lower part of the mast. There are some sailboats with unstayed masts, like the junk rig and catboat rigs. They have no standing rigging at all, and neither stays to support them. For example, a Bermuda rig has a single mast and just one headsail, thus a relatively simple rigging layout. On the other hand, schooners or ketches have a really complex rigging, i.e. with multi-spreader rigs. Apparently, the mast on a sailboat is an important component.
  5. Chainplates, Toggles, and Turnbuckles: These important components of sailboat rigging attach the shrouds to the hull. The chainplate is a metal plate that fastens to a strong point in the hull. Toggles are comprised of stainless steel fittings that absorb non-linear loads, located between the shrouds and the chainplate. Turnbuckles (or rigging screws) are also stainless steel materials that allow the shroud tension to adjust better.
  6. Parts of Running Rigging: As mentioned above, running rigging has to do about shaping, supporting, and stabilizing the sails on a sailing boat. Therefore, the necessary materials for running rigging are numerous and need further explanation. Some of these materials are: The topping lifts, the halyards, the outhauls and downhauls, the boom vangs, the sheets, and more.

Sailboat Rigging – Summary

So, what is sailboat rigging? Sailboat rigging concerns the wires, lines, and ropes that hold the rig and control the sails. To be more accurate, this means the tensioned stays and shrouds that support the mast. Rigging has to do about the booms, masts, yards, sails, stays, and cordage. Same way with cars, sailboats also have an engine, but in the form of sails. This is the standing and running rigging. When we refer to standing rigging this means that the stays and shrouds are supported by the mast. On the other hand, running rigging refers to rope halyards, sheets, and other control lines. Depending on the type of your sailboat, this sail-engine might be old, new, or maybe somewhere in between.
