How to set up your rig : tension your shrouds on masthead or fractional

If boats were cars, many of those I see sailing along would be coughing and spluttering down the motorway at 35mph in third gear with three flat tyres and a smoky exhaust. Others would cruise past in top gear at 70, making half the noise and using a fraction of the fuel.

Would these top-gear drivers be working any harder? Would they have cars that were faster by design and more expensive? Not at all. They would simply be the ones who had pumped up their tyres, learned their way around the gearbox and had their engines serviced.

It’s worth keeping an eye on your leeward cap shrouds during early-season outings after the mast has been re-stepped. The ones on this yacht could do with a little more tension

The obvious question, then, is why so many boat owners seem to leave their quest for efficiency and economy on the dockside.

One answer is that many are unaware how inefficiently their boats are performing. Another is that there’s no MOT for sailing boats and no driving test to make sure people know how to sail them (thank goodness on both counts).

Whatever the reasons, the fact remains that an efficient rig is fundamental. If the rig’s not right, the sails have no hope of setting properly.

And that’s important whether you’re racing or cruising, because sailors of both persuasions ultimately want the same: maximum lift for minimum drag.

For racers, that means more speed and better results. They carry more sail because they have more crew to handle it and more weight on the rail to balance it.

Cruisers carry less sail but, if it works efficiently, it means less heel, less leeway, better pointing, less tacking, a lighter helm and greater comfort than if it’s working inefficiently – plus the ability to get home before night falls or the pub shuts. Who can object to that?

What matters is that the sail you’re carrying is driving you forwards, not pushing you sideways.

When I question cruising sailors about the state of their rig I often get the reply ‘Oh it doesn’t matter – I’m not racing!’.

Those I know who have done something about it, however, have been delighted by the transformation their boats have undergone and have had to agree that cruising fast and comfortably is definitely better.

Setting up your boat rigging

In this article we’re going to look at how to set up the three most common types of rig: the traditional masthead with a single set of in-line spreaders, single-spreader swept fractional rigs, and fractional rigs with two sets of swept spreaders.

For simplicity we’re assuming the use of 1×19 rigging except where mentioned otherwise.

Variations in rig type are almost infinite by the time you take into account deck-stepped and keel-stepped masts, masthead rigs with swept spreaders, jumper struts, fractional rigs with in-line spreaders, and so on.

Once you understand the basics, however, you’ll find that you can apply your knowledge to good effect on most types of rig.

Rig-tuning is not only for the experts. Experience helps, of course, and a multiple-spreader fractional rig is harder to tune than an old tree-trunk of a masthead rig from the 1970s.

Nonetheless, with practice, a good eye and some observation you will probably find you can set it up pretty well.

You might want to call in a rigger or an experienced rig-tweaker to help or to do it for you the first time, and perhaps to check it periodically thereafter, but at least if you know what to look for you’ll notice when anything needs adjusting.

A word of warning when it comes to boatyards that have re-stepped your mast: sometimes re-stepping means just that and no more.

I have been on boats whose owners have assumed that the yard had set up the rig, whereas in fact it had just been dropped in and the bottlescrews hand-tensioned to stop it falling over.

It’s scary to think of the number of boats that must have been sailed in this condition.

What you will need to tune your rig Essential A calm day: don’t try setting up your rig in more than a few knots of wind A boat that’s floating level fore-and-aft (and preferably laterally as well) Screwdriver/lever bar Spanners (fixed or adjustable) Needle-nose pliers for split-pins Electrical insulation or self-amalgamating tape Lubricant for bottlescrews Tape measure (folding/small cassette type, or ideally folding rule) Useful Spring balance Long tape-measure Rig-tension gauge

The importance of enough tension: Why tight is right

If you think you’re being kind to your boat by leaving the rigging slack, think again. It’s true that some keelboats (such as Squibs and XODs) sail with the leeward cap shroud waving around in the wind, but that doesn’t work on yachts designed to go to sea.

Rigging that’s under-tensioned puts infinitely more load on the wire, bottlescrews, terminals and hull structure because of the snatch loads every time the boat falls off a wave. When it hits the bottom of the trough, anything that’s free to move gets thrown forwards and sideways before being brought up short by whatever happens to be in the way to stop it. That applies to the crew, to loose gear down below or to the mast. Think of the inertia to which a mast is subjected because of its height, and you can imagine the loads involved.

If the rigging is sensibly tight, on the other hand, movement and the consequent stresses are minimised.

Boats are built to withstand the static loads of a properly-tensioned rig, but asking them to cope with constant snatch loading is unfair – so don’t kill your boat with kindness.

As we discuss in the sections on the types of rig (below), masthead configurations with in-line spreaders need less cap-shroud tension than swept-spreader fractional rigs. This is because in-line caps are only supporting the mast laterally. The backstay stops it moving forwards, so each wire has a separate, clearly-defined role.

Aft-swept caps support the mast both laterally and fore-and-aft. Being swept aft typically about 25°, they need to be under a lot of tension to keep the forestay tight. Because they’re also at a much shallower angle to the mast, they bear between three and five times the load of the forestay.

With fractional rigs, then, it’s vital to keep the cap shrouds tight. If they’re too loose, the forestay will sag too much, the headsail will become too full and its leech will be too tight. Then the boat will become unbalanced, heel too far, make more leeway and lose both speed and pointing ability.

Structurally, under-tensioned rigging with a swept-spreader rig presents a problem in addition to the issue of snatch loading. Tension in the leeward cap shroud is important in keeping the mast in column, to the extent that Loos and Co (the manufacturer of the popular rig-tension gauges) states that a mast loses 50% of its lateral stiffness when the leeward cap goes slack. When this happens, the mast is effectively hinging around the forestay and the windward cap shroud and is far more prone to pumping as the boat bounces around.

The main reason why under-tensioned rigs on cruising boats stay standing as they do is that manufacturers build in enormous margins.

Even so, proper tension means better performance and greater safety. The ‘it doesn’t matter – I’m only cruising’ excuse for slack rigging just doesn’t cut it!

How to measure rig tension

yacht rigging tension gauge

This Loos gauge (left image) is indicating that the 6mm wire in the cap shroud is at 22% of its breaking strain (730kg). To measure the stretch, extend a tape measure (right) (or ideally a folding rule) to 2,000mm and mark this distance up the wire…

yacht rigging tension gauge

…but start with the end of the tape a couple of millimetres above the top of the swaging. As the wire is tensioned it will stretch, increasing the gap below the end of the tape.

Experienced riggers and rig-tweakers will often tension the rigging at the dockside by feel, then sight up the mast and make any adjustments under way.

Most people aren’t confident enough to do this, though – so what are the best ways to check the tension as you wind down the bottlescrews?

The simplest and quickest way is to use a rig-tension meter, such as the Loos gauge. Once you know the diameter of the wire, it will give you the load both in kg and as a percentage of its breaking strain.

The gauge for rigging of 5m and 6mm (and up to 14% of breaking strain on 7mm) typically costs around £65, while the bigger version for wire from 7mm to 10mm is closer to £200.

If you don’t have a tension gauge, you can calculate the percentage of a wire’s breaking strain by measuring its stretch, normally over a distance of 2m: when 1×19 wire has stretched by 1mm over a 2,000mm length, it’s at 5% of its breaking load whatever its diameter.

Most cruising boats have rigging made from 1×19 wire. On sportier boats it might be Dyform or rod, in which case 5% of breaking load is indicated by stretch of 0.95 and 0.7mm respectively. For the purpose or our illustrations we’ll assume 1×19.

For accurate measurement the rigging needs to be completely slack. Hold the end of the tape a couple of millimetres above the top of the swaging, then measure 2,000mm up the wire, secure the other end of the tape here and start tensioning. When the gap between the top of the swaging and the end of the tape has increased by 1mm, you have reached 5% of the wire’s breaking strain, so 3mm equates to 15% and 5mm to 25%.

Bear in mind that 1×19 wire will be affected by bedding-in stretch during its first few outings, so new rigging will need to be re-tensioned a time or two during the first season.

Sensible precautions 1. Don’t force dry bottlescrews: keep them well lubricated. 2. Don’t use massively long tools for extra leverage on the bottlescrews. If you can feel the load, you’re less likely to strain or break anything. 3. Most boats will flex to some extent when the rig is properly tensioned. If you’re concerned about excessive bend, take it easy, use a straight edge across the deck to check for movement, and seek advice. 4. The percentages of breaking load quoted assume that the rigging is of the correct diameter as specified by the designer, builder or rigger.

How to set up a masthead rig with single in-line spreaders

This is the simplest type of rig to set up. Whether it’s keel-stepped or deck-stepped and supported by forward lowers or a babystay, it’s the same basic procedure.

Step 1: Get the mast upright athwartships

yacht rigging tension gauge

Measure the distance to fixed points on both sides that are symmetrical about the centreline, such as the base of the chainplates.

If you don’t have a long tape measure, use the halyard itself (this is where a spring balance can help you gauge the same tension on each side).

Centre the masthead by adjusting the port and starboard cap shrouds until the measurements are the same, then hand-tighten the bottlescrews by taking the same number of turns on each side.

Re-check and adjust as necessary.

yacht rigging tension gauge

A long tape measure is useful for getting the mast upright.

Step 2: Setting the rake

yacht rigging tension gauge

Rake is determined principally by the length of the forestay. Some roller-reefing systems allow no adjustment but you can increase length by adding toggles.

Adjust the forestay and backstay, checking the rake with a weight suspended from the end of the main halyard. One degree of rake is about 6in (15cm) in 30ft (9m).

Hand-tight on the backstay’s bottlescrew (or gentle use of the tensioner) is fine at this stage.

yacht rigging tension gauge

Rake is measured from the aft face of the mast, at or below boom-level. If the boat’s rocking around, suspend the weight in a bucket of water to dampen the movement.

Step 3: Tighten the cap shrouds and backstay

yacht rigging tension gauge

Take no more than two or three full turns on one side before doing the same on the other.

Count carefully.

You’re aiming to tension the caps to 15% of their breaking strain, measured as explained on page 41.

That might be much tighter than you’ve ever had them before!

Tension the backstay to 15% of its breaking load.

Note: Using ordinary hand-tools on the bottlescrews, it’s hard to over-tension the rigging

Step 4: Tighten the lowers / babystay

yacht rigging tension gauge

A mast should bend forward in the middle, though only to a small extent on masthead rigs of heavy section.

This ‘pre-bend’ is principally to counter two factors in heavy weather: increased forestay loads pulling the top of the mast forward, and the head of a reefed mainsail pulling the middle aft.

Together, they can result in the middle of the mast bowing aft, which makes it unstable and is bad for sail trim. For maximum strength in extremis it should be straight.

Use the forward lowers or babystay to pull the middle of the mast forward. The bend thus induced should be no more than half the mast’s fore-and-aft measurement.

Then take up the slack in the aft lowers.

They don’t need to be tight; they’re just countering the forward pull.

Sight up the luff groove to make sure the mast is straight laterally. Correct any deflections with the lowers.

If you set up the caps properly to start with, you should not adjust them again at this stage.

Step 5: Check the rig under sail

yacht rigging tension gauge

First, make sure the leeward cap shroud isn’t waving around in the breeze. You should be able to deflect it with a finger by a few inches; no more.

If it’s too loose, take a turn or two on the leeward bottlescrew, then tack and do the same on the other side.

Now sight up the back of the mast.

It should be straight athwartships and bending slightly forward in the middle.

Athwartships deflection might make it look as though the top is falling away to one side (see diagram), but it won’t be if it was centred properly in Step 1. Straighten the middle by adjusting the lowers

If it’s straight or bending aft in the middle, try increasing the backstay tension (but not beyond 30% of its breaking strain) and, if necessary, tensioning the forward lowers/babystay and slackening the aft lowers.

Remove any lateral bends by adjusting the lowers.

Once you’re happy, lock off the bottlescrews to make sure they can’t come undone.

Inverted bend (mast bowing aft in the middle) is bad for sail trim and potentially dangerous for the rig.

Setting up a fractional rig with single, aft-swept spreaders

Widely used on smaller cruisers and cruiser/racers, this configuration needs a very different approach from an in-line masthead rig

This stage is the same as with a masthead rig (scroll up).

Step 2: Set the rake

yacht rigging tension gauge

This time, however, rake is set by the forestay and cap shrouds rather than the forestay and backstay.

With a swept-spreader fractional rig it’s the cap shrouds, not the backstay, that stop the mast moving forward. They provide both fore-and-aft and lateral support, so they’re doing two jobs.

The backstay’s principal role is to control the topmast and mast-bend. Because it’s above the point where the forestay joins the mast, it’s not pulling directly against the forestay and therefore has less effect on forestay tension. How much it pulls against the forestay depends on factors including the height of the topmast, the stiffness of the mast section and the tension of the lower shrouds (which determine the bend).

Step 3: Tighten the cap shrouds

yacht rigging tension gauge

Forestay tension is achieved primarily through the caps, and because they’re swept back at such a shallow angle they need to be seriously tight.

Their maximum tension is 25% of breaking load, but it’s best not to tension them all the way in one go because that would result in a very bent mast: tensioning the caps pushes the spreaders, and therefore the middle of the mast, forward.

Start by taking them to about 15% of breaking load, then tighten the lowers to pull the middle of the mast back so it’s straight.

This is how the swept-spreader fractional rig works: the caps and lowers are working against each other, caps pushing and lowers pulling, to stabilise the middle of the mast. Sight up the mast when it’s straight to check for lateral deflection, correcting it with the lowers.

With a flexible mast you might need to repeat the process, taking the caps to 20% before tensioning the lowers again.

Otherwise go straight to the next stage, which is to pull on the backstay.

Since the backstays on fractional rigs often have cascade purchases at the bottom you can’t measure the tension by stretch as you can with wire, so you have to do this by feel: pull it tight, but don’t go mad.

Tensioning the backstay bends the mast and therefore shortens the distance from the hounds (where the caps join) to the deck. This loosens the caps, so it’s easier to tension them back to the 20% mark.

When you let the backstay off, the caps will tension again and should be at about 25% of breaking load – but no more.

Step 4: Set the pre-bend

yacht rigging tension gauge

Take a few turns on the lowers to achieve the right amount of pre-bend. It should be more than with an in-line masthead rig, but a mast should never bend to more than 2% of the height of the foretriangle even with the backstay tensioned (that’s about 180mm in 9m, or 7in in 30ft).

Check to see how far the mast bends with a tight backstay. The optimum bend will often be determined by the cut of the mainsail, or recommended by the sailmaker or class association.

Pre-bend is vital because most fractional rigs don’t have forward lowers or a babystay, so if the mast were to bend aft in the middle (inverted bend) it could collapse.

In fresh conditions, especially under spinnaker, it’s a wise precaution never to release the backstay completely. That stops the upper section of the mast being pulled too far forward.

The caps should be tighter than with a masthead rig, with no significant slack on the leeward side when the boat’s hard on the wind and heeling 15-20°.

If the static tension is up to 25% but the leeward cap is always slack, the boat might be bending. That’s a topic beyond the scope of this article!

Sight up the mast to check the bend both fore-and-aft and athwartships, adjusting the lowers as necessary.

Setting up a fractional rig with two sets of aft-swept spreaders

As mast sections have become slimmer, this is now a popular configuration on boats between 30ft (9m) and 40ft (12m) but it’s more complex to tune.

This stage is the same as with the other types of rig.

Follow the procedure as described for single-spreader fractional rigs. Generally speaking, more rake improves upwind performance but too much will induce excessive weather helm and hamper performance downwind. Getting it right might involve some trial and error.

Steps 3 & 4: Tighten the caps and set the bend

yacht rigging tension gauge

The same fundamentals apply as for a single-spreader rig, but this time after each tensioning of the cap shrouds, which induces bend, you have to straighten the mast by tensioning both the lowers (also known as D1s) and the intermediates (D2s).

The D1s control the bend between the deck and the upper spreaders and the D2s between the lower spreaders and the hounds, so their areas of influence overlap.

On boats where the D2s terminate at the lower spreaders you have to send someone aloft to adjust them. These are referred to as discontinuous intermediates.

If they run over the spreader tips and down to the chainplates (continuous intermediates) you can do everything from on deck.

You need to achieve an even bend fore-and-aft. If the mast is bending too much at the bottom and is too straight at the top, tighten the D1s and slacken the D2s.

S-bends can creep in athwartships and make it look as though the top of the mast is off-centre. If you set up the cap shrouds properly it shouldn’t be, so don’t fiddle with them any further now: take out the bends with the D1s and D2s.

You’re aiming for a cap-shroud tension of 20-25% of breaking strain, as with a single-spreader fractional rig, and again the sweep-back of the spreader means that the caps will be slackened as you pull on the backstay.

As with other types of rig, get the boat heeling around 20° on the wind, tension the backstay and feel the leeward cap to make sure there’s only minimal slack.

Removing any kinks and S-bends can take more tweaking of lowers and intermediates, the latter being more fiddly to adjust if they’re discontinuous.

If the masthead looks as though it’s falling off one way, it’s probably because the D2 on the opposite side is too tight.

Product Description

The Loos Cableware inch tension gauge measures the tension in cables and rods to check for proper setup in sail rigging and supporting cables for large tents, radio towers, and other structures. This analog gauge shows present tension in pounds (lb.) and has a measurement accuracy of + or - 5 percent. The gauge shows readings on a graduated scale, and a calibration table on the unit converts a scale reading to the corresponding present tension and percentage breaking strength of the rope, based on 302/304 1 x 19 stainless-steel wire rope. The gauge can remain hooked on the wire during testing while the tension is adjusted. The Loos Cableware metric tension gauge has an anodized aluminum body that resists corrosion and wear. A 1/4" hole on the gauge's body allows a lanyard or hook to be attached to the gauge for securing it to the cable.

Force gauges, also called push-pull gauges or tension gauges, measure the tensile (pull) or compression (push) force applied to an object. They are used to test the strength and functionality of a variety of machines, electronic components, cables, wires, and consumer products in scientific, medical, automotive, quality assurance, and manufacturing applications. A digital force gauge shows the amount of force in digits on the gauge's display. Response time varies among digital force gauges depending on the speed of the processor. An analog (or mechanical) force gauge shows measurements on a calibrated dial. Analog force gauges are not as precise as digital force gauges, but they provide instantaneous measurements and can be used in a wider range of environmental conditions than digital force gauges. Hooks, compression plates, levers, handles, test stands, and other accessories can be used with the gauge for taking measurements on objects with a range of shapes and sizes.

Loos & Co. manufactures aircraft cable and wire rope and related measurement tools. The company, founded in 1958 and headquartered in Pomfret, CT, meets International Organization for Standardization (ISO) standard 9001.

Loos collection of tension gauges.

Tension Gauges

Loos Cableware Division offers a series of gauges to measure the tension in cables and rods from 3/32 to 3/8 inch in diameter (2.5 mm to 10 mm). These gauges are designed for setting the proper tension in the standing rigging of sailboats and also for other applications such as supporting cables for radio towers, large tents and other structures. The gauges are relatively inexpensive and are designed to be suitable for rugged marine service. The "Professional Models" provide an increasing durability, accuracy and convenience of use when compared to our popular standard models. The gauge may be hooked on the wire and will remain in position while the tension is adjusted. Manufactured of rugged anodized aluminum, this gauge is corrosive resistant and will give years of service. Detailed operating instructions are included with each tension gauge.

Professional Models - Higher accuracy and easier to use than standard models. The cable can be adjusted while the gauge remains on the cable. "Just watch the pointer move." All readings are based on 302/304 1x19 S.S breaking strengths.

The gauges measure tension over a range of approximately 5% to 25% of the breaking strength of the cable and provide an accuracy of + or - 5%.

How To Tune Your Sailboat Rig

  • August 2, 2023

Table of Contents

Sailing, with its perfect balance of adventure and tranquility, has enchanted mariners for centuries. Whether you’re cruising coastal waters or vying for victory in a thrilling regatta, your sailboat ‘s performance hinges on a seemingly unassuming yet critical aspect: rig tuning. Understanding how to properly adjust the tension in your sailboat’s standing rigging is the key to unlocking the full performance of the boat. In this article, we delve into the art of sailboat rig tuning, exploring the reasons why it is not only important but fundamental to achieving optimal performance, safety, and overall sailing enjoyment.

Why Tuning Your Rig Is Important

Tuning your sailboat rig is essential for several reasons that directly impacts your sailboat’s performance, safety, and overall experience. Here are the main reasons why rig tuning is important:

  • Sailing Performance: Properly tuned rigging ensures that the sails are set up optimally for various wind conditions. A well-tuned rig allows the sails to achieve their best shape, providing better lift and speed. It improves the boat’s pointing ability, acceleration, and overall sailing performance.
  • Sail Shape and Balance: Rig tuning helps control the shape of the sails, allowing them to perform efficiently. The correct tension in the rigging ensures the right amount of luff tension on the headsail, preventing excessive sag and maintaining proper sail balance. This, in turn, results in better boat balance and easier handling.
  • Safety and Durability: An improperly tuned rig can lead to increased stress on the rigging components, mast, and sail. Over-tensioned rigging can cause excessive loads, leading to potential failures or damage. Conversely, under-tensioned rigging can cause the mast to pump or the rig to be unstable in rough conditions. Proper tuning helps prevent rigging issues and increases the overall safety and longevity of the rig.
  • Weather Conditions: Different wind conditions require adjustments in rig tension. In light winds, a looser rig allows for a fuller sail shape, while in heavy winds, a tighter rig flattens the sails and depowers the boat. Adjusting the rig to suit the conditions helps maintain control and optimize performance.
  • Boat Balance and Helm Feel: Rig tuning affects the boat’s balance and how it responds to the helm. Properly tuned rigging ensures a balanced helm and a boat that tracks well, making it easier to steer and reducing fatigue for the crew.

Regularly checking and adjusting the rig ensures that your sailboat operates at its best, whether you’re cruising or racing. If you’re unsure about rig tuning, consider seeking advice from a professional rigger or an experienced sailor to help you get the most out of your boat.

Sailboat Rig Tuning Process

Tuning a sailboat rig involves adjusting the tension in the standing rigging (shrouds and stays) to achieve the correct balance and shape of the mast and sails. Here’s a step-by-step guide to help you tune your sailboat rig:

1. Check the Basics:

  • Ensure the boat is level and upright, preferably in the water, with the mast straight.
  • Check that all turnbuckles are free and not corroded or stuck.

2. Determine the Baseline:

  • Refer to your sailboat manufacturer’s manual, sailmaker ‘s tuning guide, or rigging expert’s recommendations for the initial baseline settings of your rigging tension. This usually includes the recommended tension for the upper and lower shrouds and forestay/backstay.

3. Loosen the Rig:

  • Loosen all the rigging turnbuckles to the point where they are free to move. This step allows you to start with a clean slate and avoids putting undue strain on the rigging while adjusting.

4. Center the Mast:

  • Use a measuring tape or a specific mast rake measurement tool to ensure the mast is centered and straight on the boat, both athwartships (side-to-side) and fore and aft.

5. Adjust Shroud Tension:

  • Begin by tensioning the lower shrouds to the recommended baseline tension. Use a tension gauge, Loos gauge, or tensiometer to achieve the desired tension. Repeat this process for both sides of the boat.
  • Next, adjust the tension in the upper shrouds to match the recommended baseline tension. Be careful not to overtighten any of the rigging.

6. Check Mast Bend:

  • Securely, attach the main halyard to the lowest point on the rear base of the mast. From there, tighten the main halyard until there is a fair amount of tension on it. The main halyard represents a straight line which is the base line for your measurement. If there is mast bend present, there will be a gap between the main halyard and middle of the mast at its furthest bend point. This gap is what is to be measured for your mast bend measurement.

7. Check Mast Rake:

  • Mast rake refers to the fore and aft angle of the mast. It can impact boat balance and helm feel. Use a mast rake measurement tool or reference marks on the boat to adjust the mast rake as needed, following the manufacturer’s recommendations or your sailmaker’s advice.

8. Check Forestay Tension:

  • Adjust the forestay tension to achieve the desired amount of luff tension on the headsail. For sailboats with adjustable backstays, make sure your backstay off off when taking this measurement. For boats with a fixed backstay, a proper forestay tension ensures proper sail shape and minimizes sag in the forestay.

9. Tune the Backstay:

  • If your boat has an adjustable backstay, adjust it to control the bend in the mast and headsail shape. More tension on the backstay usually flattens the mainsail and depowers the rig, while less tension allows for a fuller sail shape.

10. Fine-Tuning:

  • Go sailing and make small adjustments to the rig while underway to achieve the best sail shape and performance. Pay attention to how the boat behaves in different wind conditions and adjust the rig accordingly.

11. Periodic Checks

  • Rig tuning is not a one-time task. Check your rig regularly for any changes due to sailing conditions, mast compression, or wear. Make adjustments as needed to maintain optimal performance.

It’s essential to keep a record of your rigging settings and changes so you can refer back to them and fine-tune your rigging over time. If you’re unsure about tuning your rig, consider seeking advice from a professional rigger or experienced sailor.

Loos Co Cable

Loos Cableware

The industry leader in aircraft cable accessories, pulleys, swaging tools, and cable cutters, what is a tension gauge in sailboat rigging.

A tension gauge is an essential tool for eliminating any guesswork from cable or rod tension adjustment. Tension gauges measures the tension in your sailboat standing rigging. In today’s blog we are going to be looking at what a tension gauge is, how it is used in sailboat rigging, and some of the different gauges available. Continue reading to learn more about tension gauges!

Why are slack rigs worse than tight rigs?

Despite what many say, a slack rig is more damaging to a hull than a correctly adjusted tight rig. A slack rig means that you will have insufficient tension that does not reduce loads transmitted in the hull. Slack rigging means you will have excessive movement, chafe and shock loading.

Why is rigging tension important?

Rigging tension is important because mast bend is using to control mainsail shape of your boat under different wind conditions. Bend also affects the shape and trim of the jib.

What can happen without the proper tension?

The main issue that could happen is damage to your boat. Without proper tension you could also buckle your mask or cause personal injury. If you end up having excessive tension you will also damage your setup, causing stretch to either cables or rods.

How do I use a tension gauge?

On our website we have a longer form detailed video that walks you through all the steps of using a tension gauge. Our video has a full transcript and high-quality video to show you a real life demonstration on a sailboat.

Are there different types of tension gauges?

Yes! At Loos Cableware Division we offer four different types of tension gauges. We have the Model #PT-CR for cable railing, Model PT Series, Model 90 & 91, and the Model RT Series. The different tension gauges are suitable for certain size cables. On our product page you can learn about each of our tension gauges.

Now that you have learnt about tension gauges, we recommend choosing a reputable company to complete your purchase. Here at Loos Cableware Division , we carry a wide range of tension gauges and have many years of experience in helping sailors choose the correct gauge for their needs. If you have any questions, our team is happy to help! Reach out to us by email at [email protected] or by phone at (800) 321-LOOS (5667) .

How to use PT Series Tension Gauges

How to measure.

yacht rigging tension gauge

Hold the  gauge  with the left hand and place the cable between the two nylon spools as shown in Figure 1. With the right hand pull the lanyard and extend the spring until the hook on the nylon slider can be hooked on the cable as shown in Figure 2.

yacht rigging tension gauge

Release the lanyard. Read the needle position on the scale. Refer to the calibration table obtain correct tension in the cable. The  gauge can be left on the wire for “hands free” adjusting of the cable.

To assure accurate readings make sure that the slider moves freely in the frame slot and does not bind. Also, lubricate the slider slot frequently with silicone lubricant.

Note:  An extra 1/4″ inch hole is provided in the frame of the instrument for an attachment of a short lanyard and snap hook (not furnished) for securing the  gauge  to the cable. This will prevent loss of the instrument if it becomes inadvertently detached.

HOW MUCH TENSION?

Specific tension requirements for your application must be obtained from the boat, mast, or sail manufacturer or the manufacturer of the product on which the cable is used..

Table 1 recommends an initial tension setting, but there is no simple solution since the optimum rigging tension will be a function of the boat design, the rig (masthead or fractional, one or more spreaders, etc.), and even the cut of the sails. Many skippers use insufficient tension because of a fear of “breaking something.” It should be noted that on America’s Cup contenders, where electronic state of the art tension instrumentation is available, the standing rigging is set as tight as is structurally feasible.

ONE DESIGN CLASS RACING SAILBOATS

Most sail makers who produce sails for the one design classes provide each purchaser with specific set of readings on the  Loos  Model A or Model B tension  gauges  for use when setting up the standing rigging. This assures that the sails will have the correct shape when the rig is under load.

For the convenience of sailors who wish to upgrade from our Model A or B  gauges  to the professional model (PT-1, PT-2, or PT-3)  gauges  we include below a conversion chart so that the same recommended tension can be obtained with the PT-1, PT-2 or PT-3  gauges  as with the Model A or B  gauges .

When no specific requirements are provided by the sail maker, the following general comments will provide a basis for a rational procedure for tuning the rig.

FORESTAY TENSION

Masthead rig.

On the masthead rig it’s almost always advantageous to set the  forestay  tension as high as possible within the limits of structural strength. Generally, it’s possible to use 15% of the breaking strength of the cable. Thus, a  forestay  tension of 1,000 lbs. is a reasonable place to start with a 7/32″ diam ., 302/304  1×19  stainless steel cable.  Backstay  tension would, of course, have to be adjusted to maintain a straight mast with the desired  forestay  tension. Since the  backstay  makes a greater angle to the mast, the  backstay  tension will be lower than the  forestay  tension.

NOTE ! ROLLER FURLING CAN ONLY BE SET BY BACK STAY TENSION.

Fractional rig.

In a fractional rig the  forestay  does not go all the way to the masthead and  forestay  tension cannot be directly balanced by tension in the  backstay . Therefore, some mast bend is generally accepted and the mainsail is cut to fit the bend. A  forestay  tension of at least 15% of the cable strength is desirable. However, if this results in excessive mast bend it will be necessary to back off a bit. On some fractional rigs, diamond shrouds are used to reduce mast bend.

UPPER AND LOWER SHROUD TENSION

There is a simple criterion for shroud tension. The initial rigging tension should be high enough that the leeward shrouds do not go slack when sailing close-hauled in a reasonably brisk breeze. The proper value for your boat can be found by a few trial runs under sail. Once the correct tension is known, the  gauge  can be used to maintain the value.

For many boat designs a shroud tension of 10% to 12% of the breaking strength of the cable is adequate. Thus, for 7/32″, 302/ 304  1×19  stainless steel cable , the upper and lower shrouds would be set to 600 to 700 lbs. tension. On some rigs it may be desirable to carry more tension in the uppers than in the lowers.

For most fractional rigs the correct shroud tension is the same as that for a masthead rig, i. e., a tension setting that will keep the leeward shrouds from going slack. However there is one exception. On certain fractional rigs , the upper and lower shrouds lead to chain plates that are aft of the mast. The spreader is swept back. For such a rig most of the  forestay  tension is balanced by the upper shrouds. A shroud tension of approximately 20% of the cable strength may be required to achieve the desired  forestay  tension. Never exceed 25% of the cable breaking strength. (Refer to the breaking strength chart Table 1.)

NOTE ! THE INTENDED USE OF THIS GAUGE IS TO BE USED ON 302 / 304 1x19 S.S. CABLE IN APPROPRIATE SIZES. IF USED ON OTHER CABLE TYPES, SIZES, AND CONSTRUCTION YOUR READINGS WOULD BE CONSISTENT (REPEATABLE) BUT POUND TENSION VALUES WOULD DIFFER FROM THOSE LISTED ON THE LABEL. GAUGE MAY NOT READ "O" WHEN AT REST, AS THEY ARE CALIBRATED AT MIDRANGE OF TENSION.

Note if flat spots appear on nylon spools after extended use, rotate nylon spools 45°..

Standing Rigging: How Tight Is Right?

Standing rigging tension is a peculiarly under-addressed subject. Easy to see how it would worry a new boat owner or someone going to sea.

Most experts step aboard, yank or twang the shrouds and stays and mutter, Pretty slack, Too Tight, or, Thats about right.

Youll find in the sailing literature very few discussions of the question: What does tight mean?

Even riggers rarely explain how much tension they like to see.

There are a few sailors who like the rigging so tight you could send an elephant up the backstay. It can result in excessive loads and wear on fittings, chain plates and the hull. The ultimate penalty for those who can’t stand any sag in the forestay is what ocean racing sailors call a gravity storm or, less dramatically, dropping the rig.

Others like to take up the slack just enough so that the rig is at rest when the boat is motionless. This approach sometimes leaves excessive slack to leeward that can result in shock loads, excessive wear and misalignment in fittings. It may take longer, but the ultimate penalty is the same.

In between (and probably in the most logical position) are those who like to take up the slack and stretch the wire just a bit. This is frequently accomplished, at least for the stays, with an adjustable backstay. When sailing, especially on the wind, tighten down to minimize slack in the forestay. When reaching, running or at anchor, ease off.

But the question is: How much stretch…especially in the shrouds?

If you stretch the wire 5% of its breaking strength, it will be considered moderate tension. Crank in 15% of the breaking strength and it is regarded as tight. These figures apply for any diameter of wire. You need only know the wires breaking strength.

Three years ago, in the June 15, 1995 issue, we published a discussion of the views of author Richard Henderson, Skenes Elements of Yacht Design and several riggers, along with an evaluation of an excellent booklet published by Sailsystems about a Selden Mast approach (described in detail in the October 15, 1991 issue) and an entirely new method developed by Michael Dimen, who called his gadget a Rigstick.

Mentioned was the familiar (see photo) Loos rigging tension gauge, which comes in two sizes. The Model 91 ($39) is for wire 3/32″ to 5/32″. The Model 90 ($45.50) is for 3/16″ to 9/32″. The gauge depends on the bending property of aluminum plate.

The strange-looking gauges don’t willingly produce great accuracy because you have to hold one reading steady while noting another, which also requires that you make a judgment about where the centerline of the wire falls on a scale. Not easy to do.

The big name in galvanized and stainless cable (as wire is called in the trade), cable hardware and tools, Loos & Co., Inc. went looking for a better mousetrap.

Who did Gus Loos go to? The guy who designed the original gauge, his old friend, Donald J. Jordan, an 82-year-old retired Pratt & Whitney engineer who has been sailing out of Marblehead, Massachusetts, in the likes of Lightnings, Friendship sloops, Sound Schooners (which was the prized New York Yacht Club class in 1918), Pearson Wanderers and currently in a 16′ Starling Burgess design, appropriately called a Marblehead.

The old tension gauge wasnt bad, said Jordan. But it tended to get bent. Then the patent ran out and I told Gus we could do a better one.

The new version (see photo) is a distinct improvement over the old aluminum version. A better design, its also much more substantially made of aluminum, stainless and nylon.

The design problems were interesting, Jordan said. A conventional cable tension gauge has two rollers at the ends with a spring-loaded plunger in the middle and a dial gauge to measure the plunger movement. The wheels have to rotate…because they must permit some small but vital movement. That makes the tool expensive. My approach was to have two stationary wheels and a carefully contrived square slider in a arc-slot on the other.

The new Loos gauges use a long-lasting stainless spring to produce the tension. Slip the lower grooved wheels on a shroud or stay, pull the lanyard to engage the upper hook, relax, read the tension at your leisure and consult the scale to learn the pounds of pressure on the wire and the percentage of breaking strength of the wire. There are three wire gauge notches in the edge. The gauge can be left on the wire while turnbuckle adjustments are made.

The accompanying booklet, very well-done, contains a good tight discussion of the subject; some recommendations; a table on how to equalize tension in different sizes of wire, and line-drawn diagrams clearly showing rig tensions (windward and leeward) created by light, medium and heavy winds.

The wire gauge comes in three sizes, for 3/32″-5/32″, 3/16″-1/4″ and 9/32″-3/8″. West Marine sells them, respectively, for $57.99, $69.99 and $$122.99. Defender Industries cuts them to $49.95, $51.95 and $105.95. Prices in the BOAT/U.S. catalog are in between.

What if, instead of 1×19 wire, you have rod rigging? There are four new models that are bigger, heavier and, of course, more costly. They work the same, but take some arm strength. One is for .172-.250 rod, another for .281-.375. Two others models are for metric rod. West Marine sells the rod gauges for $186.99. Neither Defender nor BOAT/U.S. shows them in their catalogs.
