What is Sailboat Rigging?

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.

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:

• 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.
• 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.
• 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.
• 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.
• 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.
• 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.

Standing Rigging (or ‘Name That Stay’)

Published by rigworks on november 19, 2019.

Question: When your riggers talk about standing rigging, they often use terms I don’t recognize. Can you break it down for me?

From the Rigger: Let’s play ‘Name that Stay’…

Forestay (1 or HS) – The forestay, or headstay, connects the mast to the front (bow) of the boat and keeps your mast from falling aft.

• Your forestay can be full length (masthead to deck) or fractional (1/8 to 1/4 from the top of the mast to the deck).
• Inner forestays, including staysail stays, solent stays and baby stays, connect to the mast below the main forestay and to the deck aft of the main forestay. Inner forestays allow you to hoist small inner headsails and/or provide additional stability to your rig.

Backstay (2 or BS) – The backstay runs from the mast to the back of the boat (transom) and is often adjustable to control forestay tension and the shape of the sails.

• A backstay can be either continuous (direct from mast to transom) or it may split in the lower section (7) with “legs” that ‘V’ out to the edges of the transom.
• Backstays often have hydraulic or manual tensioners built into them to increase forestay tension and bend the mast, which flattens your mainsail.
• Running backstays can be removable, adjustable, and provide additional support and tuning usually on fractional rigs. They run to the outer edges of the transom and are adjusted with each tack. The windward running back is in tension and the leeward is eased so as not to interfere with the boom and sails.
• Checkstays, useful on fractional rigs with bendy masts, are attached well below the backstay and provide aft tension to the mid panels of the mast to reduce mast bend and provide stabilization to reduce the mast from pumping.

Shrouds – Shrouds support the mast from side to side. Shrouds are either continuous or discontinuous .

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 ).

• Cap shrouds (3) , sometimes called uppers, extend from masthead to the chainplates at the deck.
• Intermediate shrouds (4) extend from mid-mast panel to deck.
• Lower shrouds extend from below the spreader-base to the chainplates. Fore- (5) and Aft-Lowers (6) connect to the deck either forward or aft of the cap shroud.

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#.

A sailboat’s standing rigging is generally built from wire rope, rod, or occasionally a super-strong synthetic fibered rope such as Dyneema ® , carbon fiber, kevlar or PBO.

• 1×19 316 grade stainless steel Wire Rope (1 group of 19 wires, very stiff with low stretch) is standard on most sailboats. Wire rope is sized/priced by its diameter which varies from boat to boat, 3/16” through 1/2″ being the most common range.
• 1×19 Compact Strand or Dyform wire, a more expensive alternative, is used to increase strength, reduce stretch, and minimize diameter on high performance boats such as catamarans. It is also the best alternative when replacing rod with wire.
• Rod rigging offers lower stretch, longer life expectancy, and higher breaking strength than wire. Unlike wire rope, rod is defined by its breaking strength, usually ranging from -10 to -40 (approx. 10k to 40k breaking strength), rather than diameter. So, for example, we refer to 7/16” wire (diameter) vs. -10 Rod (breaking strength).
• Composite Rigging is a popular option for racing boats. It offers comparable breaking strengths to wire and rod with a significant reduction in weight and often lower stretch.

Are your eyes crossing yet? This is probably enough for now, but stay tuned for our next ‘Ask the Rigger’. We will continue this discussion with some of the fittings/connections/hardware associated with your standing rigging.

• Sailboat Rigging Basics: A Guide to Understanding and Maintaining Your Rig

Sailing is a thrilling experience, offering a unique blend of adventure, relaxation, and connection with nature. Central to this experience is the sailboat's rigging system, a complex network of ropes, wires, and chains that control the sails and mast. Understanding and maintaining your rig is crucial for safe and enjoyable sailing. Let's dive into the basics of sailboat rigging.

Understanding Your Sailboat's Rigging

Types of rigging.

There are several types of sailboat rigging, each with its unique characteristics and uses. Here are the most common ones:

• Sloop Rigging: This is the most common type of rigging, featuring a single mast and two sails.
• Cutter Rigging: Similar to sloop rigging but with an additional headsail for better performance in high winds.
• Ketch Rigging: This type features two masts, with the mizzen mast located forward of the rudder post.
• Yawl Rigging: Like the ketch, a yawl has two masts, but the mizzen mast is aft of the rudder post.
• Schooner Rigging: A schooner has two or more masts, with the forward mast shorter or equal to the aft mast(s).

Components of Rigging

Regardless of the type, all sailboat rigging systems consist of several key components. Understanding these components is the first step to mastering your rig:

• Mast: The tall vertical pole that supports the sails.
• Boom: The horizontal pole attached to the mast, which extends the foot of the sail.
• Standing Rigging: The fixed rigging that supports the mast, including the forestay, backstay, and shrouds.
• Running Rigging: The movable rigging used to control the sails, including the halyards, sheets, and outhauls.
• Blocks: Pulleys used to redirect the force applied to the running rigging.
• Winches: Devices used to tighten or loosen the running rigging.

Maintaining Your Sailboat's Rigging

Regular inspection.

Regular inspection is the cornerstone of rigging maintenance. It helps identify potential issues before they become serious problems. Here are some key areas to focus on:

• Mast and Boom: Check for cracks, corrosion, and loose fittings.
• Standing Rigging: Inspect for signs of wear, such as fraying wires, bent fittings, and rust.
• Running Rigging: Look for frayed ropes, worn blocks, and sticky winches.
• Sails: Check for tears, loose stitching, and worn corners.

Regular Cleaning

Cleaning your rigging regularly can prevent corrosion and prolong its lifespan. Here's a simple cleaning routine:

• Rinse with Fresh Water: After each sail, rinse your rigging with fresh water to remove salt and grime.
• Clean with Mild Soap: Every few months, clean your rigging with a mild soap and a soft brush.
• Lubricate Moving Parts: Apply a marine-grade lubricant to all moving parts, such as blocks and winches.

Professional Servicing

While regular inspection and cleaning can keep your rigging in good shape, it's also important to have it professionally serviced. A professional rigger can spot issues that you might miss and perform necessary repairs or replacements. Aim for a professional service at least once a year.

Learning to Sail: Practice Makes Perfect

Hands-on experience.

Understanding your rigging is one thing, but mastering it requires hands-on experience. Here are some ways to gain practical experience:

• Sailing Courses: Enroll in a sailing course to learn the basics under the guidance of experienced instructors.
• Practice Sailing: Spend as much time as possible on the water, practicing different sailing maneuvers and techniques.
• Join a Sailing Club: Joining a sailing club can provide opportunities to sail regularly and learn from other sailors.

Sailboat Parts Explained: Illustrated Guide (with Diagrams)

When you first get into sailing, there are a lot of sailboat parts to learn. Scouting for a good guide to all the parts, I couldn't find any, so I wrote one myself.

Below, I'll go over each different sailboat part. And I mean each and every one of them. I'll walk you through them one by one, and explain each part's function. I've also made sure to add good illustrations and clear diagrams.

This article is a great reference for beginners and experienced sailors alike. It's a great starting point, but also a great reference manual. Let's kick off with a quick general overview of the different sailboat parts.

General Overview

The different segments

You can divide up a sailboat in four general segments. These segments are arbitrary (I made them up) but it will help us to understand the parts more quickly. Some are super straightforward and some have a bit more ninja names.

Something like that. You can see the different segments highlighted in this diagram below:

The hull is what most people would consider 'the boat'. It's the part that provides buoyancy and carries everything else: sails, masts, rigging, and so on. Without the hull, there would be no boat. The hull can be divided into different parts: deck, keel, cabin, waterline, bilge, bow, stern, rudder, and many more.

I'll show you those specific parts later on. First, let's move on to the mast.

Sailboats Explained

The mast is the long, standing pole holding the sails. It is typically placed just off-center of a sailboat (a little bit to the front) and gives the sailboat its characteristic shape. The mast is crucial for any sailboat: without a mast, any sailboat would become just a regular boat.

I think this segment speaks mostly for itself. Most modern sailboats you see will have two sails up, but they can carry a variety of other specialty sails. And there are all kinds of sail plans out there, which determine the amount and shape of sails that are used.

The Rigging

This is probably the most complex category of all of them.

Rigging is the means with which the sails are attached to the mast. The rigging consists of all kinds of lines, cables, spars, and hardware. It's the segment with the most different parts.

The most important parts

If you learn anything from this article, here are the most important parts of any sailboat. You will find all of these parts in some shape or form on almost any sailboat.

Okay, we now have a good starting point and a good basic understanding of the different sailboat parts. It's time for the good stuff. We're going to dive into each segment in detail.

Below, I'll go over them one by one, pointing out its different parts on a diagram, listing them with a brief explanation, and showing you examples as well.

After reading this article, you'll recognize every single sailboat part and know them by name. And if you forget one, you're free to look it up in this guide.

On this page:

The hull is the heart of the boat. It's what carries everything: the mast, the sails, the rigging, the passengers. The hull is what provides the sailboat with its buoyancy, allowing it to stay afloat.

Sailboats mostly use displacement hulls, which is a shape that displaces water when moving through it. They are generally very round and use buoyancy to support its own weight. These two characteristics make sure it is a smooth ride.

There are different hull shapes that work and handle differently. If you want to learn more about them, here's the Illustrated Guide to Boat Hull Types (with 11 Examples ). But for now, all we need to know is that the hull is the rounded, floating part of any sailboat.

Instead of simply calling the different sides of a hull front, back, left and right , we use different names in sailing. Let's take a look at them.

The bow is the front part of the hull. It's simply the nautical word for 'front'. It's the pointy bit that cuts through the water. The shape of the bow determines partially how the boat handles.

The stern is the back part of the hull. It's simply the nautical word for 'back'. The shape of the stern partially determines the stability and speed of the boat. With motorboats, the stern lies deep inside the water, and the hull is flatter aft. Aft also means back. This allows it to plane, increasing the hull speed. For sailboats, stability is much more important, so the hull is rounded throughout, increasing its buoyancy and hydrodynamic properties.

The transom is the backplate of the boat's hull. It's the most aft (rear) part of the boat.

Port is the left side of a sailboat.

Starboard is the right side of a sailboat

The bilges are the part where the bottom and the sides of the hull meet. On sailboats, these are typically very round, which helps with hydrodynamics. On powerboats, they tend to have an angle.

The waterline is the point where the boat's hull meets the water. Generally, boat owners paint the waterline and use antifouling paint below it, to protect it from marine growth.

The deck is the top part of the boat's hull. In a way, it's the cap of the boat, and it holds the deck hardware and rigging.

Displacement hulls are very round and smooth, which makes them very efficient and comfortable. But it also makes them very easy to capsize: think of a canoe, for example.

The keel is a large fin that offsets the tendency to capsize by providing counterbalance. Typically, the keel carries ballast in the tip, creating a counterweight to the wind's force on the sails.

The rudder is the horizontal plate at the back of the boat that is used to steer by setting a course and maintaining it. It is connected to the helm or tiller.

Tiller or Helm

• The helm is simply the nautical term for the wheel.
• The tiller is simply the nautical term for the steering stick.

The tiller or helm is attached to the rudder and is used to steer the boat. Most smaller sailboats (below 30') have a tiller, most larger sailboats use a helm. Large ocean-going vessels tend to have two helms.

The cockpit is the recessed part in the deck where the helmsman sits or stands. It tends to have some benches. It houses the outside navigation and systems interfaces, like the compass, chartplotter, and so on. It also houses the mainsheet traveler and winches for the jib. Most boats are set up so that the entire vessel can be operated from the cockpit (hence the name). More on those different parts later.

Most larger boats have some sort of roofed part, which is called the cabin. The cabin is used as a shelter, and on cruising sailboats you'll find the galley for cooking, a bed, bath room, and so on.

The mast is the pole on a sailboat that holds the sails. Sailboats can have one or multiple masts, depending on the mast configuration. Most sailboats have only one or two masts. Three masts or more is less common.

The boom is the horizontal pole on the mast, that holds the mainsail in place.

The sails seem simple, but actually consist of many moving parts. The parts I list below work for most modern sailboats - I mean 90% of them. However, there are all sorts of specialty sails that are not included here, to keep things concise.

The mainsail is the largest sail on the largest mast. Most sailboats use a sloop rigging (just one mast with one bermuda mainsail). In that case, the main is easy to recognize. With other rig types, it gets more difficult, since there can be multiple tall masts and large sails.

If you want to take a look at the different sail plans and rig types that are out there, I suggest reading my previous guide on how to recognize any sailboat here (opens in new tab).

Sail sides:

• Leech - Leech is the name for the back side of the sail, running from the top to the bottom.
• Luff - Luff is the name for the front side of the sail, running from the top to the bottom.
• Foot - Foot is the name for the lower side of the sail, where it meets the boom.

Sail corners:

• Clew - The clew is the lower aft (back) corner of the mainsail, where the leech is connected to the foot. The clew is attached to the boom.
• Tack - The tack is the lower front corner of the mainsail
• Head - The head is the top corner of the mainsail

Battens are horizontal sail reinforcers that flatten and stiffen the sail.

Telltales are small strings that show you whether your sail trim is correct. You'll find telltales on both your jib and mainsail.

The jib is the standard sized headsail on a Bermuda Sloop rig (which is the sail plan most modern sailboats use).

As I mentioned: there are all kinds, types, and shapes of sails. For an overview of the most common sail types, check out my Guide on Sail Types here (with photos).

The rigging is what is used to attach your sails and mast to your boat. Rigging, in other words, mostly consists of all kinds of lines. Lines are just another word for ropes. Come to think of it, sailors really find all kinds of ways to complicate the word rope ...

Two types of rigging

There are two types of rigging: running and standing rigging. The difference between the two is very simple.

• The running rigging is the rigging on a sailboat that's used to operate the sails. For example, the halyard, which is used to lower and heave the mainsail.
• The standing rigging is the rigging that is used to support the mast and sail plan.

Standing Rigging

Here are the different parts that belong to the standing rigging:

• Forestay or Headstay - Line or cable that supports the mast and is attached to the bow of the boat. This is often a steel cable.
• Backstay - Line or cable that supports the mast and is attached to the stern of the boat. This is often a steel cable.
• Sidestay or Shroud - Line or cable that supports the mast from the sides of the boat. Most sailboats use at least two sidestays (one on each side).
• Spreader - The sidestays are spaced to steer clear from the mast using spreaders.

Running Rigging: different words for rope

Ropes play a big part in sailing, and especially in control over the sails. In sailboat jargon, we call ropes 'lines'. But there are some lines with a specific function that have a different name. I think this makes it easier to communicate with your crew: you don't have to define which line you mean. Instead, you simply shout 'mainsheet!'. Yeah, that works.

Running rigging consists of the lines, sheets, and hardware that are used to control, raise, lower, shape and manipulate the sails on a sailboat. Rigging varies for different rig types, but since most sailboats are use a sloop rig, nearly all sailboats use the following running rigging:

• Halyards -'Halyard' is simply the nautical name for lines or ropes that are used to raise and lower the mainsail. The halyard is attached to the top of the mainsail sheet, or the gaffer, which is a top spar that attaches to the mainsail. You'll find halyards on both the mainsail and jib.
• Sheets - 'Sheet' is simply the nautical term for lines or ropes that are used to set the angle of the sail.
• Mainsheet - The line, or sheet, that is used to set the angle of the mainsail. The mainsheet is attached to the Mainsheet traveler. More on that under hardware.
• Jib Sheet - The jib mostly comes with two sheets: one on each side of the mast. This prevents you from having to loosen your sheet, throwing it around the other side of the mast, and tightening it. The jib sheets are often controlled using winches (more on that under hardware).
• Cleats are small on-deck hooks that can be used to tie down sheets and lines after trimming them.
• Reefing lines - Lines that run through the mainsail, used to put a reef in the main.
• The Boom Topping Lift is a line that is attached to the aft (back) end of the boom and runs to the top of the mast. It supports the boom whenever you take down the mainsail.
• The Boom Vang is a line that places downward tension on the boom.

There are some more tensioning lines, but I'll leave them for now. I could probably do an entire guide on the different sheets on a sailboat. Who knows, perhaps I'll write it.

This is a new segment, that I didn't mention before. It's a bit of an odd duck, so I threw all sorts of stuff into this category. But they are just as important as all the other parts. Your hardware consists of cleats, winches, traveler and so on. If you don't know what all of this means, no worries: neither did I. Below, you'll find a complete overview of the different parts.

Deck Hardware

Just a brief mention of the different deck hardware parts:

• Pulpits are fenced platforms on the sailboat's stern and bow, which is why they are called the bow pulpit and stern pulpit here. They typically have a solid steel framing for safety.
• Stanchons are the standing poles supporting the lifeline , which combined for a sort of fencing around the sailboat's deck. On most sailboats, steel and steel cables are used for the stanchons and lifelines.

Mainsheet Traveler

The mainsheet traveler is a rail in the cockpit that is used to control the mainsheet. It helps to lock the mainsheet in place, fixing the mainsails angle to the wind.

If you're interested in learning more about how to use the mainsheet traveler, Matej has written a great list of tips for using your mainsheet traveler the right way . It's a good starting point for beginners.

Winches are mechanical or electronic spools that are used to easily trim lines and sheets. Most sailboats use winches to control the jib sheets. Modern large sailing yachts use electronic winches for nearly all lines. This makes it incredibly easy to trim your lines.

You'll find the compass typically in the cockpit. It's the most old-skool navigation tool out there, but I'm convinced it's also one of the most reliable. In any way, it definitely is the most solid backup navigator you can get for the money.

Want to learn how to use a compass quickly and reliably? It's easy. Just read my step-by-step beginner guide on How To Use a Compass (opens in new tab .

Chartplotter

Most sailboats nowadays use, besides a compass and a map, a chartplotter. Chartplotters are GPS devices that show a map and a course. It's very similar to your normal car navigation.

Outboard motor

Most sailboats have some sort of motor to help out when there's just the slightest breeze. These engines aren't very big or powerful, and most sailboats up to 32' use an outboard motor. You'll find these at the back of the boat.

Most sailboats carry 1 - 3 anchors: one bow anchor (the main one) and two stern anchors. The last two are optional and are mostly used by bluewater cruisers.

I hope this was helpful, and that you've gained a good understanding of the different parts involved in sailing. I wanted to write a good walk-through instead of overwhelming you with lists and lists of nautical terms. I hope I've succeeded. If so, I appreciate any comments and tips below.

I've tried to be as comprehensive as possible, without getting into the real nitty gritty. That would make for a gigantic article. However, if you feel I've left something out that really should be in here, please let me know in the comments below, so I can update the article.

I own a small 20 foot yacht called a Red witch made locally back in the 70s here in Western Australia i found your article great and enjoyed reading it i know it will be a great help for me in my future leaning to sail regards John.

Rope is unemployed cordage. In other words, when it is in a coil and has not been assigned a job, it is just a rope.

On the other hand, when you prepare a rope for a specific task, it becomes employed and is a line. The line is labeled by the job it performs; for example, anchor line, dock line, fender line, etc.

Hey Mr. Buckles

I am taking on new crew to race with me on my Flying Scot (19ft dingy). I find your Sailboat Parts Explained to be clear and concise. I believe it will help my new crew learn the language that we use on the boat quickly without being overwhelmed.

PS: my grandparents were from Friesland and emigrated to America.

Thank you Shawn for the well written, clear and easy to digest introductory article. Just after reading this first article I feel excited and ready to set sails and go!! LOL!! Cheers! Daniel.

steve Balog

well done, chap

Great intro. However, the overview diagram misidentifies the cockpit location. The cockpit is located aft of the helm. Your diagram points to a location to the fore of the helm.

An excellent introduction to the basic anatomy and function of the sailboat. Anyone who wants to start sailing should consider the above article before stepping aboard! Thank-you

James Huskisson

Thanks for you efforts mate. We’ve all got to start somewhere. Thanks for sharing. Hoping to my first yacht. 25ft Holland. Would love to cross the Bass Strait one day to Tasmania. 👌 Cheers mate

Alan Alexander Percy

thankyou ijust aquired my first sailboat at 66yrs of age its down at pelican point a beautifull place in virginia usa my sailboat is a redwing 30 if you are ever in the area i wouldnt mind your guidance and superior knowledge of how to sail but iam sure your fantastic article will help my sailboat is wings 30 ft

Thanks for quick refresher course. Having sailed in California for 20+ years I now live in Spain where I have to take a spanish exam for a sailboat license. Problem is, it’s only in spanish. So a lot to learn for an old guy like me.

Very comprehensive, thank you

Your article really brought all the pieces together for me today. I have been adventuring my first sailing voyage for 2 months from the Carolinas and am now in Eleuthera waiting on weather to make the Exumas!!! Great job and thanks

Helen Ballard

I’ve at last found something of an adventure to have in sailing, so I’m starting at the basics, I have done a little sailing but need more despite being over 60 life in the old dog etc, thanks for your information 😊

Barbara Scott

I don’t have a sailboat, neither do l plan to literally take to the waters. But for mental exercise, l have decided to take to sailing in my Bermuda sloop, learning what it takes to become a good sailor and run a tight ship, even if it’s just imaginary. Thank you for helping me on my journey to countless adventures and misadventures, just to keep it out of the doldrums! (I’m a 69 year old African American female who have rediscovered why l enjoyed reading The Adventures of Robert Louis Stevenson as well as his captivating description of sea, wind, sailboat,and sailor).

Great article and very good information source for a beginner like me. But I didn’t find out what I had hoped to, which is, what are all those noisy bits of kit on top of the mast? I know the one with the arrow is a weather vane, but the rest? Many thanks, Jay.

Louis Cohen

The main halyard is attached to the head of the mainsail, not the to the mainsheet. In the USA, we say gaff, not gaffer. The gaff often has its own halyard separate from the main halyard.

Other than that it’s a nice article with good diagrams.

The Running Rigging On A Sailboat Explained

The running rigging on a sailboat consists of all the lines used to hoist, lower, and control the sails and sailing equipment. These lines usually have different colors and patterns to easily identify their function and location on the vessel.

Looking at the spaghetti of lines with different colors and patterns might get your head spinning. But don’t worry, it is actually pretty simple. Each line on a sailboat has a function, and you’ll often find labels describing them in the cockpit and on the mast.

In this guide, I’ll walk you through the functions of every component of the running rigging. We’ll also look at the hardware we use to operate it and get up to speed on some of the terminology.

The difference between standing rigging and running rigging

Sometimes things can get confusing as some of our nautical terms are used for multiple items depending on the context. Let me clarify just briefly:

The  rig  or  rigging  on a sailboat is a common term for two parts, the  standing , and the  running  rigging.

• The  standing rigging  consists of wires supporting the mast on a sailboat and reinforcing the spars from the force of the sails when sailing. Check out my guide on standing rigging here!
• The  running rigging  consists of the halyards, sheets, and lines we use to hoist, lower, operate and control the sails on a sailboat which we will explore in this guide.

The components of the running rigging

Knowing the running rigging is an essential part of sailing, whether you are sailing a cruising boat or crewing on a large yacht. Different types of sailing vessels have different amounts of running rigging.

For example, a sloop rig has fewer lines than a ketch, which has multiple masts and requires a separate halyard, outhaul, and sheet for its mizzen sail. Similarly, a cutter rig needs another halyard and extra sheets for its additional headsail.

You can dive deeper and read more about Sloop rigs, Ketch Rigs, Cutter rigs, and many others here .

Take a look at this sailboat rigging diagram:

Lines are a type of rope with a smooth surface that works well on winches found on sailboats. They come in various styles and sizes and have different stretch capabilities.

Dyneema and other synthetic fibers have ultra-high tensile strength and low stretch. These high-performance lines last a long time, and I highly recommend them as a cruiser using them for my halyards.

A halyard is a line used to raise and lower the sail. It runs from the head of the sail to the masthead through a  block and  continues down to the deck. Running the halyard back to the cockpit is common, but many prefer to leave it on the mast.

Fun fact:  Old traditional sailboats sometimes used a stainless steel wire attached to the head of the sail instead of a line!

Jib, Genoa, and Staysail Halyards

The halyard for the headsail is run through a block in front of the masthead. If your boat has a staysail, it needs a separate halyard. These lines are primarily untouched on vessels with a furling system except when you pack the sail away or back up. Commonly referred to as the jib halyard.

Spinnaker Halyard

A spinnaker halyard is basically the same as the main halyard but used to hoist and lower the spinnaker, gennaker, or parasailor. 

The spinnaker halyard is also excellent for climbing up the front of the mast, hoisting the dinghy on deck, lifting the outboard, and many other things.

A sheet is a line you use to  control and trim a sail to the angle of the wind . The  mainsheet  controls the angle of the mainsail and is attached between the boom and the  mainsheet   traveler . The two headsail sheets are connected to the sail’s clew (lower aft corner) and run back to each side of the cockpit.

These are control lines used to adjust the angle and tension of the sail. It is also the line used to unfurl a headsail on a furling system. Depending on what sail you are referring to, this can be the  Genoa sheet , the  Jib sheet , the  Gennaker sheet , etc.

The outhaul is a line attached to the clew of the mainsail and used to adjust the foot tension. It works runs from the mainsail clew to the end of the boom and back to the mast. In many cases, back to the cockpit. On a boat with  in-mast furling , this is the line you use to pull the sail out of the mast.

Topping lift

The topping lift is a line attached to the boom’s end and runs through the masthead and down to the deck or cockpit. It lifts and holds the boom and functions well as a spare main halyard. Some types of sailboat rigging don’t use a topping lift for their boom but a boom vang instead. Others have both!

Topping lifts can also be used to lift other spars.

A downhaul is a line used to lower with and typically used to haul the mainsail down when reefing and lowering the spinnaker and whisker poles. The downhaul can also control the tack of an asymmetrical spinnaker, gennaker, or parasailor.

Tweaker and Barber Haul

A tweaker is a line, often elastic, attached to the sheet of a headsail and used to fine-tune the tension on the sheet.

Barber haul

A barber haul is a line attached to a headsail’s sheet to adjust the sheeting angle to the wind. It is often used to pull the clew further toward the center or outboard than the cars allow.

Boom Preventer

A boom preventer is a line attached to the boom’s end when sailing off the wind. Its function is to hold the spar in place and prevent it from swinging wildly.

If the boat were to get an accidental gybe, it could cause serious damage to the rigging or even harm people on board. It is important for the rigger to be cautious when setting up the boom preventer.

Running Backstay

Running backstays is similar to a normal backstay but uses a line instead of a hydraulic tensioner. Some rigs have additional check stays or runners as well.

Bonus tip: Reefing

The term reefing is used when reducing the effective sailing area exposed to the wind of a given sail. Headsails are usually reefed by partially furling them in, and they often have marks for what we refer to as 1st, 2nd, and 3rd reefs.

The mainsail is reefed similarly with an in-mast furling or in-boom furling system.

On a traditional mast, we use a system called slab reefing. The system has reefing lines running through the boom to reinforced points on the luff and leech, allowing you to pull the sail down to the boom and effectively reduce the sail area.

Having at least two reefing points in the mainsail is normal, but most cruising sailboats have 3. The 3rd is used for the heaviest conditions, giving you only a tiny bit of sail area exposed to the wind.

You want to reef your sails  before  the wind increases to a point where your boat gets overpowered.

It is essential to practice your reefing technique . You will find yourself in situations with rapidly increasing winds where you need to reduce your sails quickly.

Rule of thumb:  If you think setting a reef might be a good idea, do it.

Shaking a reef  is the term used when we sail with a reefed sail and want to increase the sail area back to full.

Hardware used for sail handling and the running rigging

Furling system.

Most sailboats have their headsail on a furling system. A furling system is a tube that runs along the forestay from the bottom furler drum to the masthead swivel.

This system allows you to roll the headsail around the forestay, making furling the sail in and out accessible. It is also convenient when reefing the sail when the wind picks up, as you can easily do this from the safety of the cockpit. These furling systems come in manual versions and electric versions.

In-mast furling

In-mast furling is a system that rolls the mainsail in and out of the mast. To unfurl the mainsail, we use the  outhaul .

In-boom furling

In-boom furling is a system that rolls the mainsail in and out of the boom. This system has been costly and has mostly been seen on big yachts earlier. They are becoming more affordable and common on smaller boats, though. To unfurl this setup, we use the main halyard.

A Stack pack is also called a Lazy Bag or Lazy Pack. It is a bag with a zip attached to the boom where the mainsail is stored when unused. It protects the mainsail from UV rays from the sun and weather elements. It is a very nice and tidy way to store the mainsail and reefing lines if you don’t have in-mast or in-boom furling.

Lazy Jacks is a system of lines running from the stack pack to the mast. The Lazy Jacks guide the mainsail up and down from the Stack Pack and prevent it from falling down on the deck. It is also possible to rig Lazy Jacks without a Stack Pack.

A block is a pulley with a sheave wheel. Blocks are used to change the direction of a pull on a line or rope and give a mechanical advantage. They have many uses, especially onboard sailboats.

A winch is a metal drum that gives you a mechanical advantage to control and tighten lines. These can be operated by turning a rope around it and pulling manually or by a winch handle to get more force. Most modern winches are self-tailing, which means they lock the line on so you can winch the line without holding on to it. Some boats even have electrical winches operated by a button.

Mainsheet Traveler

The mainsheet traveler is a horizontal track that the mainsheet is attached to through a series of blocks. The traveler enables you to adjust and lock the boom at an angle and also plays a critical part in trimming the mainsail.

Most cruising sailboats have their traveler attached to the top of the coachroof in front of the spray hood. A racing boat typically has the traveler in the cockpit near the helm to give the helmsman better control over the mainsheet.

The cars are basically a pulley or block attached to a track on the port and starboard deck that your headsail sheets run through. Cars are used to control the angle of the sheet between the clew and the deck. The cars are handy when you trim the sail to set the right balance of tension between the foot and leech, depending on your point of sail.

The jammer is used to lock a line in place. Most sailboats use these for locking the halyards, mainsheet, outhaul, reef lines, traveler lines, boom vang lines, etc. You can pull or winch a line through a closed jammer, but it won’t run away if you let go of it unless you open the lock. 

As I explained earlier, it is normal to have most or all of the lines led back to the cockpit, and they are usually run through a series of jammers.

The jammers are often labeled with the name of the line it locks, which makes it easier to remember which line goes where.

Spinnaker Pole

A spinnaker pole is a spar used to wing out a headsail when sailing off the wind, particularly the spinnaker. The spinnaker pole should have the same length as the distance between the mast and the forestay measured along the deck. We use a fore and aft guy and the pole’s topping lift to rig a pole correctly.

The rigging varies depending on the layout of the boat, but it usually looks like this:

• One line runs from the bow to the end of the pole.
• An aft line runs from near the stern to the end of the pole.
• A topping lift is used to raise and lower the pole.

Whisker Pole

A whisker pole is similar to the spinnaker pole and is rigged similarly. It is typically built lighter and attached to a track on the mast. These can be found in fixed lengths or adjustable lengths. Ideally, the length should be the same as the foot of the headsail you intend to pole out.

Boom Vang/Rod Kicker

The Boom Vang has a few different names. Rod-kicker, kicking strap, or kicker. It is used to tension the boom downwards. When you are sailing downwind and have the boom far out, the mainsheet won’t pull the boom down as much as inboard, and you can then use the vang to adjust the twist and shape of the mainsail.

Mooring line

A mooring line is a traditional rope lead through a fairlead to the vessel’s cleat and a mooring buoy, key, or pontoon.

Final words

Congratulations! By now, you should have a much better understanding of how the running rig on a sailboat functions. We’ve covered the different lines, their purpose, and the hardware used to operate them. I hope you’ve enjoyed this guide and learned something new.

Now it’s time to take what you’ve learned and put it into practice by getting out on the water, setting sail, and getting hands-on experience with the lines.

Sailboat Rigging:  Part 1 - Standing Rigging

When we talk about sailboat rigging, we mean all the wires, ropes and lines that support the rig and control the sails. To be more precise, the highly tensioned stays and shrouds that support the mast are known collectively as standing rigging , whilst the rope halyards, sheets and other control lines come under the heading of running rigging.

Some sailboats with unsupported masts, like the junk rig and catboat rigs have no standing rigging at all.

Bermudan sloops with their single mast and just one headsail will have a relatively simple rigging layout - those with a single set of spreaders especially so.

The most complex rigging of all will be found on staysail ketches and schooners with multi-spreader rigs.

Fairly obviously, the mast on a sailboat is an important bit of kit.

Let's make a start by taking a look at the standing rigging that holds it up...

Standing Rigging

Cruising sailboats will have their mast supported by 1 x 19 stainless steel wire in most cases, but some racing boats may opt for stainless steel rod rigging. Why? Well rod rigging has a stretch coefficient that is some 20% less than wire, but...

• It's more expensive than wire;
• It's more difficult to install and adjust;
• It suffers from metal fatigue, signs of which are difficult to spot;
• It's less flexible and has a much shorter useful life span

So it's 1 x 19 stainless steel wire for us cruising types.

Cap Shrouds

These are the parts of a sailboat's rigging that hold the mast in place athwartship. They're attached at the masthead and via chainplates to the hull.

Lower Shrouds

Further athwartship support is provided by forward and aft lower shrouds, which are connected to the mast just under the first spreader and at the other end to the hull.

The mast is supported fore and aft by stays - the forestay and backstay to be precise.

Cutter rigs require an inner forestay upon which to hang the staysail, which unlike a removable inner forestay, becomes an element of the overall rig structure.

As this stay exerts a forward component of force on the mast, it must be resisted by an equal and opposite force acting aft - either by swept-back spreaders, aft intermediates or running backstays.

Another stay that deserves a mention is the triatic backstay. This is the stay that is found on some ketches, and it's the stay from the top of the mainmast to the top of the mizzen mast.

It's a convenient alternative to a independent forestay for the mizzen. Although it makes a great antenna for an SSB radio , it does ensure that if you lose one mast, you're likely to lose the other.

Multi-Spreader Rigs

With the lower shrouds supporting the mast athwartship at the lower spreaders, intermediate shrouds do the same thing for any other sets of spreaders. These take the form of a diagonal tie between the inner end of one spreader and the outer end of the spreader below it.

Continuous or Discontinuous Sailboat Rigging

The shrouds on all single-spreader rig and some double-spreader rigs are continuous. With three or more spreaders, this arrangement becomes impractical - discontinuous rigging is the way to go. So what's that?

Well, if you consider the mast rigging as a series of panels, ie:~

• Lower Panel ~ From the deck to the first set of spreaders;
• Top panel ~ From top set of spreaders to the masthead;
• Intermediate Panels ~ Between each set of spreaders.

Then discontinuous rigging is when each shroud is terminated at the top and bottom of each panel.

The main benefits of discontinuous sailboat rigging is:~

• The rig can be more accurately set up, and
• Weight aloft is substantially reduced;
• It can be replaced in small doses.

Chainplates, Turnbuckles and Toggles

It's through these vitally important sailboat rigging components the shrouds are attached to the hull.

The chainplate is a metal plate bolted to a strongpoint in the hull, often a reinforced section of a bulkhead.

It must be aligned with angle of the shroud attached to it through a toggle, to avoid all but direct tensile loads.

Whilst cap shrouds will be vertical - or close to it - lower shrouds will be angled in both a fore-and-aft direction and athwartship.

Artwork by Andrew Simpson

Toggles are stainless steel fittings whose sole purpose in life is absorb any non-linear loads between the shrouds and the chainplate.

Consequently, they must be of a design that enables rotation in both the vertical and horizontal planes.

Note the split pin! These are much more secure than split rings which can gradually work their out of clevis pins - with disastrous results.

Turnbuckles, or rigging screws or bottlescrews, are stainless steel devices that enables the shroud tension to be adjusted.
