Ropes, Sheets and Halyards — Learning the Language of Sailing

There are plenty of ropes on a sailing boat. Sailors just seem determined not to call most of them ropes.

One of the first slightly bewildering things you discover when learning to sail is that sailors appear to have developed an entirely new vocabulary for perfectly ordinary objects.

You look at a piece of rope and say:

"Could you pass me that rope?"

An experienced sailor may reply:

"Which one?"

You point.

"That one."

And then comes the answer:

"Oh, the jib sheet."

At first it can feel as though sailing terminology exists purely to make beginners feel that they have accidentally walked into an advanced language lesson.

It doesn't.

There is actually a very good reason for most of it.

On a sailing dinghy there may be several lines within arm's reach. They may look quite similar, but pulling one could trim the jib, another could raise the sail, another could flatten the mainsail and another might release something you most definitely didn't intend to release.

So sailors give ropes names according to what they do.

Once you understand that, the mysterious language begins to become surprisingly logical.

First of All: Are They Really Not Ropes?

This is one of those sailing sayings that is partly useful and partly exaggerated.

You certainly can call the material rope.

But once a particular piece of rope has been given a job aboard the boat, sailors normally refer to it by the name of that job.

A rope used to control a sail becomes a sheet.

One used to raise something becomes a halyard.

One tied to the bow for securing the boat may be the painter.

Others become outhauls, downhauls, control lines and so on.

So rather than learning an enormous collection of random nautical words, think of it this way:

The name often tells you what the line is supposed to do.

And that matters enormously when somebody needs you to do something quickly.

The Sheet — The Rope You Will Probably Use Most

For the beginner, sheets are among the most important lines aboard the boat.

A sheet controls the angle of a sail relative to the boat and therefore the wind.

On a simple dinghy you are likely to encounter:

the mainsheet, controlling the mainsail;
the jib sheets, controlling the jib.

And yes, confusingly, the word sheet has absolutely nothing to do with the large piece of fabric you put on a bed.

If somebody tells you:

"Sheet in."

they mean pull the appropriate sheet in, bringing the sail closer towards the centreline of the boat.

If they say:

"Ease the sheet."

they mean allow some of it out.

That distinction very quickly becomes important.

"Ease the Jib Sheet"

Imagine we are sailing along the Thames.

I am on the jib and somebody at the helm says:

"Ease the jib sheet slightly."

That is a remarkably precise instruction.

It tells me:

which sail is involved — the jib;
which control to use — its sheet;
what to do — ease it;
approximately how much — slightly.

Compare that with:

"Pull that rope over there."

Immediately several questions appear.

Which rope?

Pull it towards where?

How far?

And should I actually be pulling it at all?

Worse still, the person giving the instruction may be pointing while looking somewhere completely different.

On a quiet afternoon this is merely amusing.

Approaching a mark with several other boats nearby, it becomes rather more important.

Sailing terminology is therefore not really about sounding nautical.

It is about communicating quickly and unambiguously.

Halyards — Getting the Sails Up

A halyard is normally used to raise something.

On a training dinghy you might have a:

Mainsail halyard — raises the mainsail.

Jib halyard — raises the jib.

When rigging the boat ashore, these are some of the lines you will encounter before you even start sailing.

A useful beginner's association is simply:

Halyard = up.

It isn't a perfect definition for every vessel ever built, but it is a very useful way of remembering its basic purpose.

You attach the appropriate halyard to the sail and use it to raise the sail up the mast.

Then, depending upon the particular boat, it will be secured in a cleat or another fitting.

Which brings us neatly to another piece of sailing vocabulary.

Cleats — Where the Rope Stays Put

A cleat is used to hold a line in position.

Different boats use different types.

You might encounter:

cam cleats;
clam cleats;
horn cleats;
jammers and similar devices.

You don't need to learn every type on your first day.

What you do need to understand is the basic idea.

You pull the line to the required position and then secure it so that you don't have to sit there holding it continuously.

Some controls are adjusted occasionally and then cleated.

Others — particularly sheets — may be adjusted constantly while sailing.

Learning how a particular cleat releases is just as important as learning how it grips.

This is something worth practising while the boat is safely ashore.

Pull the line.

Cleat it.

Release it.

Do it again.

It is much easier to work this out beside the boat than when somebody suddenly shouts:

"Let it off!"

The Painter — Surprisingly Little to Do With Decorating

Another wonderfully misleading nautical term is the painter.

Sadly, it does not mean the person responsible for touching up the scratches you have just added to the boat.

The painter is a line normally attached towards the bow and used for jobs such as securing the dinghy to a pontoon, bank or other suitable point.

It may also be used when handling or towing the boat, depending on circumstances and equipment.

For a beginner, think:

Painter = securing line at the front of the dinghy.

It is one of those lines that may seem unimportant until the boat begins drifting away from the pontoon without you in it.

At that moment, knowledge of the painter suddenly becomes extremely valuable.

Control Lines — Changing the Shape of the Sail

Sheets mainly control the position of the sails.

But sails are not rigid structures.

They change shape.

That shape influences how effectively they produce driving force.

Most dinghies therefore have additional control lines allowing the crew to adjust the sail.

You don't need to become an expert sail trimmer during lesson four.

For now, simply recognise that these controls exist and understand broadly what they do.

The Kicking Strap — Or Vang

The kicking strap, usually called the vang in some parts of the sailing world, runs between the boom and a lower point around the mast or mast base area.

Its job is essentially to control how much the boom can rise.

This affects mainsail shape and particularly the amount of twist higher up the sail.

Pulling more kicking strap on generally holds the boom down more firmly.

Releasing it allows the boom greater freedom to rise.

You will hear plenty of discussion around sailing clubs about how much kicker should be used in different wind conditions.

As a beginner, you don't need to memorise a complicated trimming guide.

Just remember:

Kicker controls the boom's tendency to lift.

Later, this apparently innocent rope becomes part of the fascinating world of trying to make a boat go approximately 0.1 knots faster than your friends'.

On the RS Toura and some of the other boats they don't have a Vang. Instead they have a Gnav ( Vang backwards) and that is because their Vang is a rod and it goes up instead of down. It gives more room for the crew but works the same.

The Outhaul — The Clue Is in the Name

The outhaul is one of the easier sailing terms to remember because the name tells you what it does.

It pulls the lower rear corner of the mainsail — the clew — outwards along the boom.

This changes the tension along the foot of the sail and therefore helps control sail shape.

More outhaul generally makes the lower part of the sail flatter.

Less allows it to become fuller.

For your first few sails, you may barely touch it.

But it is useful to know what it is when someone says:

"Put a little more outhaul on."

You no longer have to stare at the boat hoping one particular piece of string will somehow identify itself.

Downhaul and Cunningham

Depending upon the dinghy, you may also encounter a downhaul or Cunningham.

These are used to apply downward tension associated with the sail, particularly controlling tension in the luff — the forward edge of the sail.

Again, exactly how the system works depends upon the boat.

For the beginner, the important idea is that increasing this control generally increases tension down the forward edge of the sail and changes its shape.

If your particular training boat doesn't have an obvious Cunningham, don't worry.

Different boats have different arrangements.

This is one reason learning on a straightforward club training dinghy is so useful. You can understand the basic principles without immediately being confronted by every possible control invented during the last century.

"What's That Rope?" Is Actually a Very Good Question

One of the best ways to learn sailing terminology is not to sit at home trying to memorise diagrams.

Stand beside an actual boat.

Pick up a line and follow it.

Ask:

Where does it start?

Where does it finish?

What moves when I pull it?

Suddenly the terminology becomes practical.

Pull the mainsheet and the boom moves.

Pull the outhaul and the bottom of the mainsail is tensioned.

Release a halyard and the sail comes down.

Pull the kicker and the boom is restrained from lifting.

The language becomes attached to an action.

That is far easier to remember than simply learning a vocabulary list.

A Simple Exercise Before You Sail

Next time you're beside a dinghy, try finding the following without anyone telling you:

mainsheet;
jib sheet;
mainsail halyard;
jib halyard;
painter;
kicking strap;
outhaul;
any other control lines;
the cleats that secure them.

Then choose one line at a time and trace where it goes.

Don't start enthusiastically pulling everything.

Somebody may have spent the previous ten minutes setting it correctly.

Instead, ask an experienced sailor:

"Is this the outhaul?"

or:

"Does this line control the kicker?"

You'll probably get far more explanation than you expected.

Sailors are remarkably good at answering a five-second question with a 15-minute discussion.

And that is often where some of the best learning happens.

Learning the Words Makes Learning the Sailing Easier

At first, sailing seems filled with jargon.

Bow.

Stern.

Port.

Starboard.

Sheets.

Halyards.

Kickers.

Outhauls.

It can sound like you need to learn another language before anybody will let you near the water.

You don't.

Learn the words as you use the equipment.

Soon somebody will say:

"Ease the jib."

And instead of wondering which mysterious rope they mean, your hand will automatically move to the correct sheet.

That is a small moment, but it is quite an important one.

You are no longer translating sailing language in your head.

You are beginning to think like a sailor.

Why Precise Language Matters

There is a broader lesson here.

Sailing terminology did not develop simply because sailors enjoy obscure words — although occasionally one might wonder.

The terminology allows people aboard a boat to communicate accurately.

"Pull that rope."

is vague.

"Ease the jib sheet."

is precise.

"Release the mainsail halyard."

is precise.

"More kicker."

is precise.

And once several people are working together aboard a boat, particularly when racing or manoeuvring in confined water, precise communication makes everything calmer, quicker and safer.

The strange vocabulary stops being a barrier.

It becomes a tool.

The Next Time Someone Says "It's Not a Rope…"

So yes, there really are ropes aboard sailing boats.

But most of the useful ones quickly acquire names according to the jobs they perform.

Don't worry if you forget those names initially.

Everyone did.

Look at where the line goes.

See what it controls.

Use it.

Ask questions.

Eventually the strange collection of coloured ropes around the cockpit stops looking like spaghetti and starts looking like a collection of useful controls.

And perhaps the real sign that you are becoming a sailor is the first time a newcomer points at the jib sheet and asks:

"What does that rope do?"

…and you find yourself saying:

"Ah. Technically, that's a sheet."

Then you will know they have got you.

Practical Challenge

The next time you visit your sailing club, stand beside a rigged dinghy and identify:

sheet — halyard — painter — kicker — outhaul — cleat.

For each one, don't merely learn its name.

Work out what happens when it is used.

That is when sailing terminology stops being jargon and starts becoming sailing.

My name is Philip. I started sailing when I was 65.

I joined a club and because my son had already been part of a club for many years - borrowing all types of boat. He knew what we needed and the type of boat I would require.

So we did by an RS Toura - a virtually unsinkable dinghy which has given me the confidence to experiment and learn and take my RYA exams and become a competent sailor and then to move up to the boat of my dreams - the A-Rater.
