Sailing Terms Everyone Should Know

By: American Sailing Sailboats

Knowing the right sailing terms to use on board a boat is not JUST a way of sounding super cool and impressing your friends. (Though it works for that, too.) It’s actually very useful, and sometimes crucial in communicating while you’re sailing. Some of the vocabulary used on board boats can sound arcane, which it is! That’s part of what’s fun about it; we’re still using terms that have been used by sailors for hundreds of years. So when you know your terminology, you’re participating in the grand sailing tradition, and you don’t have to say, “Can you hand me that…thing?”

Here are the key sailing terms you’ll want to know as you begin learning to sail !

• Port: Facing forward, this is anything to the left of the boat. When you’re onboard, you can use this term pretty much any time you would normally say “left.” Starboard: Facing forward, this is anything to the right of the boat. Same deal as “port”–only the opposite.
• Bow/Stern: The bow is the front of the boat, the stern is the back. Anything near the front of the boat is referred to as being “forward,” and anything toward the back is “aft” or “astern.”
• Point of Sail: The boat’s direction relative to the wind. For example, if you’re going straight into the wind, your point of sail is called “in irons.” (Note: This isn’t a good place to be!) If the wind is blowing straight over the side of the boat, that’s called a “beam reach.” There are 8 commonly used points of sail, and it’s a good idea to familiarize yourself with them before going out.
• Helm: Where you steer the boat. Usually this is a big wheel, but on smaller boats it can be a tiller, which is basically a long wooden stick. Either of these can be used to control the boat’s rudder.
• Keel: The keel is a long, heavy fin on the bottom of the boat that sticks down into the water. It provides stability and is the reason why modern sailboats are nearly impossible to capsize.
• Heeling: This is the term for when a sailboat leans over in the water, pushed by the wind. There’s nothing else like the thrill of heeling over as your sails fill and your speed picks up!
• Tack: This term has two distinct meanings, both of them very important. As a verb, to tack is to change direction by turning the bow of the boat through the wind. As a noun, your tack is the course you are on relative to the wind. For example, if the wind is blowing over the port side, you are on a port tack. If it’s blowing over the starboard side, you’re on a…you guessed it…starboard tack.
• Jibe: A jibe is another way of changing direction, in which you bring the stern of the boat through the wind. Whether you choose to tack or jibe entirely depends on the situation–what’s around you, and the direction of the wind.
• Windward: The side of the boat closest to the wind. When heeling over, this will always be the high side.
• Leeward: The side of the boat furthest from the wind. When heeling over, this will always be the low side.
• Lines: On board a boat, this is what you say instead of “ropes.”
• Mainsail: The big triangular sail just aft of the sailboat’s mast. As the name suggests, this is the boat’s largest and most important sail. Running along its bottom edge, the mainsail has a thick pole called the boom.
• Jib: The next most common sail on any boat. The jib can always be found forward of the mast, and unlike the mainsail, does not have a boom.

  Getting familiar with these sailing terms is an important step. Not only will you sound like you know what you’re doing, you’ll quickly begin to realize that with the right practice and training, you really DO know what you’re doing!

The Only 50 Sailing Terms You'll Need To Know (With Pictures)

Ever get confused by all those odd sailing terms? Starboard, tack, jib… Well, no worries. In this article, I'll go over the most important sailing terms for beginners.

This is a great resource for beginning sailors that need an overview of the most important sailing terms without drowning in it . For a comprehensive list, check out this Wikipedia glossary of nautical terms . There are A LOT of nautical terms there. But no one in his or her right mind will read through that entire page (it has 48.434 words!). There are a lot of obscure words listed that no one really uses anyways. So in this article, I've filtered out the most important ones to get you up to speed quickly. I've also added pictures so you'll know what we're talking about.

Let's jump straight in. For the sake of good manners, I have categorized them by topic. If you are looking for a specific term, just ctrl+f your way directly to it.

Here are the only 50 sailing terms you'll need to know:

Orientation

Parts of the boat, parts related to sails, other terms.

...because it isn't as easy as 'left', 'right', 'front' and 'back'. No, no.

Port is the left side of the boat. It's as simple as that. I'm not entirely sure why don't they just call it 'left' these days. The name came to existence because centuries ago, you always docked your big boat with the harbor (port) being on the left side. And the word stuck with us till today.

Starboard is the right side of the boat. If in a car, you say 'look to your right', on a boat, you say 'look to the starboard'. Again, you might as well just call it 'right'. Oh, wait… you wouldn't seem as cool if you did. Alright, let's keep calling it starboard.

The bow is the front of the boat. The word likely comes from the Middle Dutch 'boech' (nowadays spelled 'boeg'). If you call it 'front' instead, you will get your message across just as well. But it won't get you the admiring looks from those around you.

Stern is the back of the boat. That is where you, as a captain, will spend most of your time. Whether you will force your crew to call it 'stern' or let them use the word 'back', like the dry land creatures they are, is up to you. After all, you are the captain.

The windward side of the boat is the side facing into the wind. So if the wind is coming from the right side, the windward side is on the right. Unlike some of the previous ones, this term actually makes sense - at times you need to talk about a direction not fixed in relation to the boat, but rather relative to the direction of the wind.

Leeward side of the boat is the lee side. If the wind is coming from the right side, the leeward side is on the left. Note that neither windward nor leeward specify the angle of the wind. Thus even if the wind was coming 20 degrees right off of the direction of the boat, so almost from the front, left would still be considered the leeward side.

Since there are gadgets and parts on the boat that you won't see anywhere else, it only makes sense they all have their own special name. You want to know these because unlike the direction terms where you can do with 'left' and 'right', you don't want to call a tiller 'that stick thing back there'.

Helm is the boat's steering wheel. In this case, I forgive those who came up with this name, since it is shorter than 'steering wheel' and thus saves valuable time that we can spend on sailing. Though I doubt linguistic economy was the reason.

Tiller is the long stick that operates your boat's rudder. A steering stick, if you will. It has the same function as a helm does, but it is usually used on smaller boats, where a helm would take up too much space. Or by people who prefer it to a helm, since a tiller offers a bit more in terms of response.

The rudder is the long, flat piece of metal or wood that sits underwater below the back of your boat. Connected to a tiller or a helm, it is used to control the direction of your exciting voyage. By the way, since aerodynamics and hydrodynamics work in similar ways, a plane is also operated by a rudder. Though that one isn't underwater. Hopefully.

Hull is the boat's body. Whatever the shape or size, whether opened on top (like a dinghy) or closed by a deck, (like a traditional sailboat) it's all called a hull. Structures sitting on top of the deck, like a deck salon or cabins, aren't considered a part of the hull anymore.

The keel is an underwater fin below the boat's belly. The sizes and shapes vary, sometimes it is relatively short and goes deep, (fin keel) sometimes it runs from the front all the way to the back (full keel or ballast keel). It is there mainly for stability and to help maintain forward direction when sailing.

The cockpit is the area where a boat is operated from. On sailboats, it is usually in the back and it is an open area without a roof, though this varies. You will find the rudder control and winches there. In 'smaller' (below 70 ft or so) sailboats this area oftentimes doubles as a deck dining place with a table and seating.

The bimini is a sun roof or shade that is covers the cockpit, and is generally attached to a steel frame which runs over the cockpit.

This is where things tend to get confusing. There are a whole lot of parts and a whole lot of names for them. It pays off for you and your crew to know them though, as during the stormier moments, you all want to be on the same boat (ha, ha) linguistically, as every second counts.

Lines are ropes. Not much more to add here. I suppose a 'line' sounds a bit fancier than a 'rope'. One thing this article will teach you is that if there is the slightest crack in the wall of your boat, linguistic elitism will leak its way in.

This one is quite self-explanatory. The mainsail is the main, largest sail of the boat, attached to the mast on the side and the boom at the bottom. It has a triangular shape and serves as the most important sail, the first one you should get acquainted with if you are just starting out.

The jib is the front sail of your boat, sometimes also called the genoa. That is as long as you are sailing on the traditional sloop - the classical two sail setup you see the most often. The jib is wrapped around the line that goes from the top of your mast to the boat's bow.

Spinnaker is the third type of sail you are the most likely to encounter on your travels. It goes in front of your boat and has a half balloon or kite-like shape. This is because it is constructed specifically for sailing downwind. Its purpose is to grab as much backwind as it can and drag your boat forward. It is not attached to the boat most of the time like the mainsail or the jib, instead, it is stored separately and used only when needed.

The mast is the tall, vertical pole that goes from the floor of your salon, through the deck, meters above your boat. All the sails are attached to it, also radars and lights, giving sailboats radio and visual visibility far greater than that of equally sized motorboats. Take that, ya noisy stinkies!

The boom is the horizontal pole right above the deck, attached to the mast at the right angle. The bottom of the mainsail is attached to it, it is used to determine its shape and direction. It is also where the mainsail is often stored, folded and covered with a protective sheet. The boom is also among the top causes of injuries on a sailboat, as in certain winds it tends to swing with force powerful enough to knock a few grown men overboard. Stay away from its reach at all times when under sail.

The forestay is the cable going from the top of the mast to the very front of the bow. It is there to hold the mast in place. Sometimes you will find people refer to it as the 'headstay'. It is often made of steel, so it is safe to hold on to it when you are pretending to be Jack on the bow of the Titanic's, the boat hits a wave and you lose your balance.

This diagram is from our guide on sailboat parts , which I really recommend for beginners. It walks you through all the most important sailboat parts in normal words.

The backstay is the cable going from the top of the mast to the very back of the boat. In many cases it is doubled at the bottom, each end attached to one corner of the back of the boat so that they don't interfere with space and provide more stability for the mast. Just as with forestay, these are made of steel.

Shrouds are the cables going from the top of the mast to the left and right side of the boat. Sometimes there are four, two on each side. Together with forestay and backstay, they make sure your mast withstands all the forces exerted on it when the wind pushes the sails.

The foot of a sail is its bottom edge. If you imagine a sail as a triangle, the base is called the foot. You probably won't use this term while sailing, but when researching proper sail trim, it is likely you will stumble upon it.

This diagram is again from our guide on sailboat parts , which I really recommend for beginners. If you're looking for a good starting point to learn your sailboat ins and outs, this article is perfect for you.

Leech of a sail is its back side edge. Thus it is the part closest to you when you are standing at the helm. Just as with the foot, this is a term quite often used when describing sail trimming techniques, since the shape of the leech determines the shape of the whole sail.

Luff of a sail is its front side edge. Thus the part the furthest from you when you are standing at the helm. For mainsail, it is the edge that is right next to the mast, for the foresail it is the edge right next to the forestay. Just as with foot and leech, the shape of these edges determines the overall shape of the sail so you will most likely encounter these terms in trimming lessons and tutorials.

The head of a sail is its top corner. On a traditional sloop, you will have the 'main head' and the 'jib head'. There is usually a reinforcing patch of some kind on these corners, as you will find a hole in them to which a line is attached.

It's also something else entirely, but more on that later ...

Halyard is the line attached to the sail head. On your boat, you will most likely have two. The 'main halyard' which is what you use to hoist your mainsail if it is folded on the boom, and the 'jib halyard' which holds the jib head up.

Clew of a sail is its back corner. The line attached to the 'main clew' will be used to hoist your mainsail if it is wrapped inside of the mast. The line attached to the 'jib clew' will be used to open the jib on most sailboats since jibs are most often wrapped around the luff.

Telltales are light, usually cotton or wool pieces of ropes attached to a sail, showing you the airflow around it. These are important because they help you determine if your trim is effective or not. Because of the material they are made of, you might sometimes encounter them being called 'woolies'.

Vang, or a 'boom vang' is a device pulling the boom down. This is important because it controls the tension of the mainsail, influencing its shape greatly. You won't find it on every boat though. Holiday cruisers often don't have it, as it is a piece of equipment focused on performance and thus not necessary for your average trip.

Topping Lift

The 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.

Also referred to as a 'horse', the traveler is a side to side track to which the boom is attached, allowing the control of the extent to which the boom goes off the centerline. This is important especially if the wind is blowing from behind and you need to control the angle of the mainsheet.

Outhaul is the line attached to the mainsail or the jib clew, allowing the control of the foot tension. This is important for determining the sail shape - for instance in stronger winds, you want the foot to be more tense to achieve a more effective airflow as opposed to slower winds where you can allow the foot to arch more.

Reefing is reducing the sail area to lessen the power exerted on it by the wind. You may want to reef if the wind is getting too strong for your boat, or if it is changing too rapidly, as an overpowered boat is difficult to control. Fun fact: they say that when you feel you need to reef because the wind got too strong, it is already too late to reef.

A batten is a slat placed horizontally in the body of the sail to support its shape. You will not find them on all sailboats, it is a performance-enhancing element that many cruisers lack. It helps tremendously as without it, sails tend to belly out and lose their shape under certain conditions.

The cleat is a piece of fitting where a line can be secured and immobilized, even if under great tension. It usually consists of two cogwheel-like pieces fastened close to each other, in the middle of which the rope is placed, unable to move thanks to friction. This type is great as it allows for a quick release. Sometimes though, it is a simple piece of metal or plastic where the rope is tied.

...and then there are all those things that just float around you when sailing, those little things that are the reason for you having to carry a dictionary in your pocket.

Fenders are bumpers allowing some contact with other boats or piers while docked, without scraping the paint. They are often balloon-shaped, made of rubber or some relatively soft material. They are usually attached to the boat's railing and you move them around as you need.

The beam is the width of the boat. Could be just called width, I know. The word comes from the fact that there are transverse reinforcing beams in the boat hull and deck. Next time you are choosing your charter boat for holidays, you will know what this attribute means.

True wind is the actual direction and speed of the wind. This is different than the apparent wind, which is wind direction and speed relative to the boat. Apparent wind is a combination of the true wind and the headwind, which is the wind the boat experiences solely by being in motion.

The berth is a sleeping space on a boat. Thus if a boat has eight berths, it means eight people can comfortably sleep on it. Note that this often includes the salon couches, so a berth is not necessarily a space in an actual bed for one person.

Boat's draft is the distance from the water surface to the deepest point of the boat. In other words, the draft is the minimum water depth you can go to and not scrape your hull or keel. Better double this number when sailing, just to be safe, as hitting the seabed can have disastrous consequences.

Tacking is zig-zagging towards your destination. It is necessary in case your destination is in the direction of the wind since sailboats can not go directly into it. Since the closest to the wind direction you can sail is around 45 degrees, you have to change direction left and right from your desired course.

This diagram is from our guide on sailing into the wind for beginners , which explains in 7 simple steps how to get good upwind sailing performance.

Bareboat is a boat without a skipper. You will encounter this term in boat charters and it means you rent the boat without any crew, thus you need to operate it yourself. It is the best way to sail unless you enjoy living in close proximity to a sea wolf who you also have to feed.

The chart is a nautical map. It differs from classical maps as it depicts information relevant for a sailor - water depth, navigational hazards, seabed material, anchorages and so on. Formerly made of paper, these days made of ones and zeros. As is everything in this digital world.

We have a guide that explains all the different chart types clearly for beginners - read it here .

Galley on a boat is its kitchen. Also a medieval warship, but if you find this term in a boat's description, war is not likely what they have in mind.

Heads on a boat is the bathroom. Though in all my years of sailing I have never ever heard anybody use this term instead of a 'bathroom'. I suppose saying that you are going to use the heads just sounds odd.

A knot is the unit of speed of boats. It is equal to one nautical mile per hour. That is 1.852 kilometers per hour or 1.5078 miles per hour. Though a bit confusing and annoying at times, you will have to get used to this, since most of your boat's instruments will use this unit. It dates all the way back to the seventeenth century when boat's speed was measured with a rope with knots tied on it.

Mooring is attaching the boat to a buoy that is anchored to the seabed. This is usually a cheaper option to docking in a marina. It also means larger space between the boats anchored in the same area, thus more privacy. Though you will have to use your dinghy to get to shore instead of just stepping on the pier directly from your deck.

A salon on a boat is its living room. On smaller boats, it is usually in the same room as the boat's kitchen and the captain's corner with navigation instruments.

A skipper is the captain of a sailboat. If you ask me, the word 'captain' is much better than a skipper, which to me sounds like a small boy who sits on the shore the whole day, skipping stones. But hey, who am I to talk.

A monohull is a classical boat with a single hull. A boat with two hulls is called a catamaran, or a 'cat'. Although rare, there are also trimarans, boats with three hulls. Multihulls with four or more hulls do happen but they are an unnecessary freak of nature.

So there you have it. Fifty sailing terms you will encounter the most when traveling or learning. I know you might think some of them are a bit unnecessary since they have a perfectly fine 'real world' equivalent. I agree. But until the tradition changes, you might want to get some of these under your skin.

A boat's freeboard is the distance from the upper deck to the waterline. Classic yachts have low freeboards, so they appear to lay deeper in the water, as opposed to more modern yachts, which have a higher freeboard. It literally means 'free-board' : the amount of visible board.

The lunch hook is a light anchor setup that is used to moor small yachts temporarily. It typically uses a lightweight anchor on a short scope that takes little effort to set. The lunch hook is only used when the crew is on board and will be monitoring the anchor.

In naval architecture and ship design: “Head” = WC = Bathroom. A toilet is still a toilet. The toilet is in the head. In olden day, the toilet was a hole in the head.

Hi Rich, you’re absolutely right. I’ve corrected the error. Thanks for pointing it out.

A nautical mile is one minute of a degree, so if you travel 60 nautical miles that means you have gone 1 degree around the “globe”. (Note: arc length not actual length.) This is the original definition. As such the average was agreed upon and the lengths given a standardization. Which you mentioned.

As such 1 knot is to travel one nautical mile in an hour.

Also 1.5078. I think you made a mistake as it should be 1.1508 miles to a nautical mile.

Thanks for the information. Sorry about being a pedantic mathematics teacher.

So, where is the “nautical mile” calculated from, the equator or one of the tropic lines?

Just to clarify a nautical mile. If you draw an imaginary line from the North Pole or South Pole to the center of the Earth and draw another line from the center of the Earth to any point on the equator, it forms a right angle, which is 90 degrees. This equates to latitude. The equator is 0 degrees and the poles are 90 degrees. Your latitude is the angle that you are north or south of the equator. Each degree of latitude is divided into 60 minutes. A minute of latitude is the same distance matter where you are on Earth. It is 6,076 feet. This is the length of a nautical mile. A statute mile is 5,280 feet, so a nautical mile is 1.1508 statute miles.

Thank you very clear and well explained. Hopefully I’ll remember The Fifty

KöhnSharkösz

Really? No gunwale? No transom? Those or basic terms to the Washington State Boater Education Card required to operate watercraft here. Definitely more of a “need to know” than bimini.

Thank you, those definitions and explanations were clear, thorough, and helpful. I’m really glad I found my way (somehow) to your webpage.

Filter the sailing terms by letter:

A | B | C | D | E | F | G | H | I | J | K | L | M | N | O | P | Q | R | S | T | U | V | W | X | Y | Z

The sailing terms beginning with the letter A are:

• Abaft : Toward the stern of a boat and behind the middle of the boat
• Abandon Ship : An instruction to leave the boat immediately. This is an emergency situation and everyone needs to get off the boat
• Abeam : On a line at right angles to a ship's or an aircraft's length
• Able Seaman : A crew member with experience and expertise in working on deck and handling the sailboat's rigging and equipment
• Aboard : This is a nautical term to describe being on or in a boat
• Above Board : This means anything on or above the boat deck
• Adrift : Not anchored or not securely moored, drifting with the current or wind
• Aft : The aft is the area at the back of the boat. It is also known as the stern
• Aft cabin : This is a sleeping cabin at the aft side (rear) of the boat
• Aftmost : Furthest towards the stern (back) of the boat
• Aground : When the boat is resting on or touching the ground below the bottom of the water

20 Sailing & Sailboat Terms

Within boating, sailing has its own specific vernacular. You’ll want to understand it before you step aboard a sailboat to help crew or when taking a lesson.

• Apparent wind – the combination of true wind and the motion of the boat at the time. It’s the wind you feel onboard.

• Jibing (also spelled gybing) – changing direction where the stern swings through the eye of the wind.
• Leeward – the direction away from where the wind is blowing.
• Mainsail – the primary sail on a boat which is usually attached in some way to the mast and boom. On most sailboats it’s the primary source of power.

Sailing Terms: A Complete Guide

Last Updated by

June 15, 2022

Learning sailing terms when you first get into boating can be a daunting task.

Some sailing terms are logical, like 'fore' means forward or front of the boat, while others might as well be in a different language. Athwartship, for example. Nothing in our daily lexicon gives any clues as to what that might mean. Like it or not, it's time to dust off the old noodle and get to memorizing some new vocab words!

Knowing the difference between a clew and a tack, a luff and a leech, will help you communicate with your sail maker regarding which part of your sail needs resewn. If you need to have your rigging adjusted, you must know the difference between your shrouds and your stays, your standing rigging vs. your running rigging.

By educating yourself in the correct names of all parts of your sailboat, you can avoid situations in which you may need to use terms such as ‘thingy’ or ‘that round part at the end of that thing’. While even the most seasoned sailor occasionally troops over the vernacular, it is always beneficial to have as wide a nautical vocabulary as possible. Many in the sailing community get by without knowing the entire sailing dictionary, but if you’re interested in avoiding vocabulary embarrassment, check out the list I’ve compiled of sailing terms that every sailor ought to know.

I’ve been sailing on and off throughout my life and I know from experience that it is incredibly helpful to know the correct terms for each part of your sails, rigging, and boat.

Sailors are among the kindest, most helpful people you’ll ever meet. But, if you’re looking for help on why you’re not getting the most speed out of your mainsail and you know don’t know the correct terms for each part of the sail, it may be hard to get advice from you fellow sailor on why ‘the back of the mainsail is flappy’. They would be more likely to give useful advice if you’re able to tell them that you’re struggling to keep wind in the roach of your mainsail. Check out my list of sailing terms and see if a few don’t stick. I’ve done my best to include pictures when possible.

Table of contents

Sailing Terms

Abeam : When an object, craft or island is abeam your vessel, that means that it is off the side of your boat. It is 90 degrees from the centerline of your boat.

Abaft : Toward the stern. “Honey, have you seen my boat shoes?” “They’re abaft the navigation table!” This is the opposite of forward.

Aft : In the stern of the boat. For example, the back cabin is referred to as the aft cabin.

Apparent wind : The wind direction and speed which the crew observes to be blowing in combination with the true wind. This is often different from the true wind direction and speed due to the boat's motion.

Astern : The area behind the boat. If you go astern, you are going in reverse.

Athwartship : Directionally perpendicular to the centerline of the boat.

Backing (a sail) : Forcing the sail to take wind into its opposite side by pulling the sail to the opposite side of the boat.

Backstay : The wire that runs from the back of the boat to the mast head. This prevents the mast from falling forward.

Bailer : Any scoop-like container that is used to remove water from within a vessel’s hull.

Ballast : Weight which adds stability to the vessel. The weight usually is composed of lead or iron and placed low in the boat's hull, such as within the keel.

Batten : a thin, flexible strip (often fiberglass) that is inserted into the main sail to help it stay open to the wind. The batten runs from the back edge of the sail (leech) toward the front edge (luff).

Beam : The width of the vessel at its widest point.

Beam reach : Sailing with the wind blowing perpendicular to the direction the boat is traveling.

Bearing off or Bearing away : Steering the boat away from the direction in which the wind is blowing.

Bend : a knot which connects two ropes.

Berth : A slip, a mooring, or a bed within the boat.

Bight : A bend or loop in a rope. When a rope forms a bight, it has changed direction 180 degrees.

Bilge : The lowest area within a boats hull. This area collects water which is then pumped overboard by a bilge pump.

Bimini : The covering over the cockpit. Usually constructed from a stainless steel frame covered with canvas or fiberglass. It provides protection from sun and rain, but not wind.

Binnacle : The pedestal centrally located in the cockpit that generally holds the steering wheel and navigational instruments.

Block : A pulley.

Boom : This pole runs perpendicular to the mast and holds the bottom of the mainsail in place. Its position is adjustable side to side as needed for the wind direction.

Boom vang : A tackle which ensures that the boom does not lift upward from wind pressure in the mainsail.

Boot Top or Boot Stripe : The stripe of tape or paint between the boat's underwater (bottom) paint and it’s above water (topside) paint.

Bow : Front end of the boat

Bowsprit : The forward most protruding pole or platform which some boats possess. This spar allows for the sails and rigging to be attached further forward.

Broach : When a boat sailing downwind accidentally ends up sideways to the waves and heels over dangerously. This can be caused by large seas or poor steering.

Broad reach : Sailing with the wind coming off your stern quarter. If you’re standing at the helm facing the bow, the wind is blowing halfway between the side and the back of the boat.

Bulkhead : The walls in a boat which run athwartship, or perpendicular to the centerline of the vessel.

Capsize : When a vessel tips over past 90 degrees.

Catamaran : A vessel with two hulls.

Centerboard : A retractable keel which helps the sailboat maintain course and stability underway. When raised, the vessel is able to enter shallow waters.

Centerline : An imaginary line that runs from the center of the bow to the center of the stern.

Chainplate : A metal plate that is secured to the boat's hull to which wires supporting the mast are attached. The chainplates may be exterior or interior, visible or hidden.

Chock : A fitting that a line passes through to change direction without chafing.

Clew : The lower back corner of a sail. This is where the foot and leech of the sail meet.

Close-hauled : Sailing as close to the direction the wind is coming from as possible with the sails pulled in tight. (See Points of Sail for infographic.)

Close Reach : Sailing between close hauled and beam reach. (See Points of Sail for infographic.)

Coamings : The lip around a hatch or window which stops water from entering. Also the raised area around the cockpit to keep out water.

Cockpit : The area from which steering occurs. This can be in the center of the boat or in the back of the boat.

Companionway : The doorway into the cabin.

Cotter pin : a bendable metal pin which is inserted into a metal rod then bent to lock it in place.

Daybeacons : Markers for navigation which are on posts. These are red or green.

Dead run : Sailing with the wind coming from directly behind the boat. Sails are fully out to catch the wind.

Dead reckoning : Determining a vessel's position by knowing the direction and speed traveled.

Dinghy : A small boat which is used to travel to shore from the main vessel. This can be propelled oars or a motor.

Dodger : The structure at the front of the cockpit which protects the cockpit and companionway from wind and spray. This is generally made of stainless steel frame covered with canvas and plastic windows. It can also be a solid structure with solid windows.

• Glossary: essential terms a sailor should know

We have put together a comprehensive list of essential sailing terms to enhance your nautical knowledge. Delving into diverse areas such as meteorology, navigation, and boat equipment, our glossary covers sail types, boat components, and crucial units of measurement and abbreviations that every sailor should be familiar with. Plus, you'll find terms unique to charter boats, the boat rental process, safety at sea, signalling aids, and modern sailboat technology.

Anchor windlass is a mechanical device used to hoist and lower the anchor and its chain on a boat. It operates under high tension and typically has its own circuit breaker to protect it from electrical overloads. When using an anchor windlass, it is essential to allow for short breaks during operation to prevent it overheating and any resultant damage to the equipment.

Anticyclone is an area of high air pressure.

Apparent wind is the wind we perceive when we are on board and results from the vector sum of the real wind and the wind generated by our motion while sailing. The topic of apparent wind is covered in detail in our article — Apparent vs. true wind .

Autopilot is a device designed to steer a boat along a predetermined course. It independently adjusts the rudder as required, ensuring the vessel follows the set path to its destination as accurately as possible. 

Baby net or safety net is a safety feature that prevents small children from falling off the deck into the water. It is a net similar to a fishing net, which is installed along the boat's railings. A baby net does not come as standard with a rental boat, so always discuss it with the salesperson when booking if you want to order the net from the charter company. We discuss safety features in our article — Sailing with kids: how to keep all of you safe and happy .

Safety nets on the boat effectively prevent children from falling into the water.

Barber hauler is a sail control device used to adjust the angle of the jib or genoa sail in relation to the wind, mostly found on more sporty boats. It consists of a line or tackle system attached to the clew of the sail, allowing sailors to fine-tune the sail's position for optimal performance and improved windward efficiency.

Bathing or swim platform , is a foldable structure located at the stern of a boat, providing easy access to the water for swimmers or during training activities. When sailing, it is advised to keep the bathing platform closed and secured in place, rather than left extended.

Batten is the reinforcement in the mainsail. Mainsails are generally classified based on their shape and construction, with variations such as full-batten, partial-batten, or no-batten mainsails.

Beaufort scale  is a widely recognized scale in the sailing world. It categorizes wind forces and their corresponding effects on sea surface conditions, allowing skippers to estimate wind strength visually. By observing the behaviour of the sea surface and the wind's impact on it, sailors can use the Beaufort scale to make informed decisions about their sailing course and speed.

Bearing compass is a type of compass that is used to determine the bearing, or direction, of an object or location relative to the compass itself. It is commonly used in navigation to determine the direction of a distant landmark or to maintain a specific course while sailing.

Bimini  is an alternative term for a sun canopy that provides shade for the helmsman's station and the rear portion of the cockpit. In the rain, it serves as a slight protection from the water. Often, however, sailors fold it up for sailing, and sometimes there is no other way to do it, as the mainsail sheet passes through it.

Boom is a horizontal spar, typically made of aluminum or carbon fiber, that attaches to the mast and holds the foot of the mainsail. It runs perpendicular to the mast and is held in place by a combination of topping lift, mainsheet, and outhaul.

Bow thruster  is a mechanism located at the bow of a vessel that assists with maneuvering while in port. It is not intended to replace the main engine and should not be used while sailing. The primary function of a bow thruster is to help shift the boat's bow to port or starboard. It's essential to operate the bow thruster with caution, as it has a high voltage. Use short, intermittent presses (2-3 seconds) rather than prolonged holds to prevent the bow thruster from burning out and becoming inoperable.

Bowsprit is a spar that extends from the bow of a sailboat. It is used to attach the forestay, which supports the mast, and to extend the sail area forward. On historic ships it is slightly angled upwards towards the sky. On more modern boats it extends straight out from the bow and may be retractable or foldable to make docking and storage easier.

Brackish water is water that is neither salty like the sea nor fresh like freshwater streams. Its salinity is somewhere in between. It is most often found at the mouths of rivers or in lakes by the sea.

Breeze is a periodic wind phenomenon caused by differences in air temperature between day and night. According to the time when it occurs, it is distinguished between day (sea) and night (land). The breeze is a beautiful sailing breeze. Read more about breezes in our guide — Understanding land and sea breezes: how they can affect your sailing .

Buoy field  is an arrangement of multiple buoys within a bay, anchored to concrete blocks on the seabed. Typically, a fee is charged by the operator for using these buoys, but the cost is generally lower than docking at a pier or marina.

Cardinal marks are navigational aids that indicate the location of safe water relative to a hazard. They are named after the four cardinal points: North, East, South, and West.

This is what a foil looks like on a racing catamaran.

Gangway is a temporary bridge or walkway that connects a boat to a dock, allowing people to move between the two structures.

Gennaker is an additional sail that is similar to a genoa. It is made of lighter material, which makes it ideal for lighter winds. Gennakers often have distinctive colours, and there are several reasons why sailors might want to rent and try one out.  Check out our 5 reasons to rent a gennaker .

Genoa , also known as genoa jib , is a type of sail that is positioned forward of the mast and is used on sailing boats. It typically covers the area from the mast to the bow of the boat, and is larger than the mainsail. It can range in size from 100% to 150% of the foretriangle, which is the triangle formed by the mast, forestay, and deck.

GPS , which stands for Global Positioning System, is a satellite-based navigation system that provides location and time information anywhere on Earth. Sailors can use an electronic GPS device to accurately determine their position on the water.

Gulets are double-masted boats designed and built based on traditional Turkish wooden sailing boats. One of the typical destinations for gulets, which we also offer, is Turkey.

Gybe or jibe is a sailing maneuver where the sailboat's stern is turned through the wind to change the wind direction from one side of the boat to the other, usually while sailing downwind. The boom of the sail swings across the boat during a gybe, and it should be performed carefully to prevent accidents and damage to the boat and crew.

Harness is a safety device used in sailing that is attached to a sailor's body or life jacket and secured to the boat's deck with a buckle to prevent falling overboard.

Halyard  can is a rope used to raise different types of sails such as the mainsail, jib, genoa, spinnaker, and gennaker. Each sail will typically have its own dedicated halyard to hoist it up the mast.

Keel , which is the heaviest component located beneath a boat and has the lowest center of gravity, plays a vital role in maintaining the vessel's stability. It typically accounts for up to 40% of the boat's weight and can have a fin or bomb shape. The keel's primary purpose is to stabilize the boat and prevent it from capsizing by helping to restore it to a horizontal position when it is tilted due to wind or waves.

Kicker , also known as a boom vang or vang , is a mechanical device consisting of ropes or a piston that is connected between the deck, boom, and the base of the mast. It is used to control the shape of the mainsail by adjusting the tension on the leech of the sail and controlling the boom's vertical position.

Preventer  or boom preventer is an auxiliary line or rope that is rigged from the end of the boom to a sturdy point on the deck, mast, or other secure attachment point on the boat. The purpose of the preventer is to restrict the boom's movement and prevent an accidental or unintentional jibe, which can happen when sailing downwind or on broad reach courses.

Propeller is a device consisting of blades that rotate to provide propulsion for a boat's engine. It is often located at the stern (back) of the boat and is powered by the boat's engine.

Propwalk is a phenomenon that occurs when a boat's propeller produces a lateral force that causes the boat's stern to move to one side when the engine is in gear. This is particularly noticeable at slow speeds and when maneuvering in tight spaces, such as a marina or dock.

Propwash is the turbulence created by the rotation of the propeller. Propwash deflecting off an angled rudder allows even large boats to turn in a tighter space.

Quebec flag signal (yellow) in the International Code of Signals means "My vessel is healthy and I request free pratique" which is a signal made by a ship entering port to request permission to enter and clear customs and immigration. It is usually used when sailing abroad. To learn more about crossing borders, take a look at Can you cross national borders with a charter boat?

Self-tacking jib is a type of headsail that is specifically designed to tack without the need for adjusting the sail position or manually pulling on the sheets. The sail is attached to a track or a traveler that runs athwartships on the boat and allows the sail to pivot and change sides without having to be moved or adjusted manually.

Shackle is a small metal device used to attach a line to a sail. It is used to connect the sail to the halyard or other lines on the boat. It can also be used to connect different sails together or to connect a sail to a spar or other structural element of the boat.

Sheet is a rope or line used to control the angle and shape of a sail. There are different sheets for different sails, such as the mainsheet for the mainsail, the jib sheet for the jib sail, and the spinnaker sheet for the spinnaker sail.

Shrouds are actually a type of standing rigging, which are the fixed lines or wires that support the mast of a sailboat. They run from the mast to the sides of the boat, and help to keep the mast upright and stable.

Spreader  is a horizontal strut that extends from the mast to the side of a sailboat, providing support for the mast and helping to spread the shrouds that support the mast.

Spinnaker pole  is a long and sturdy pole used to hold the clew (bottom corner) of a spinnaker sail out from the mast of a sailing boat.

Steering wheel is the device used to control a boat's direction. It is connected to the rudder blade through a steering mechanism. Boats can have one or two steering wheels depending on size and design.

Storm sails are special sails, usually orange in colour, whose small surface area and strong material allow sailing in storms. The sails are not installed on the boat all the time, they need to be unpacked from the hold when needed. Ask at check-in where the storm sails are located on the boat.

Storm sails often have a distinctive colour.

Skipper is just another name for the captain, the skipper of a yacht. Would you like to become a skipper too? Take a look at our sailing courses .

Spinnaker is a large, lightweight and often colourful sail that is designed to be used when sailing off the wind, such as on a reach or a downwind leg.The spinnaker is attached to the boat's mast and is supported by a spinnaker pole.

Spin-out refers to a situation in which a boat, while sailing downwind, loses control and starts turning towards the wind.

Sprayhood is a protective covering, typically made of canvas or other durable material, that is installed over the companionway (entrance to the cabin) of a sailboat. Its primary purpose is to shield the cockpit and the interior of the boat from wind, spray, and rain while underway

SRC stands for Short Range Certificate , which is a certification required for operating a marine VHF radio.

Starboard is the term used to describe the right-hand side of a boat when facing forward.

Stay is a term used to refer to a piece of rigging that helps support the mast of a sailing vessel. It typically runs from the top of the mast to the bow of the boat, forming a triangle shape along with the mast and the boat's deck.

Stratus is a type of low-level cloud characterized by its uniform, featureless appearance that often covers the entire sky.

Synoptic map , also known as a weather map, is a graphical representation of current weather conditions created using data collected from weather stations, satellites, and other sources.

Tack is the maneuver of turning the sailboat against the wind.

Telltales are pieces of yarn or fabric that are attached to a sail, stay, or rigging on a sailboat. They are used as a guide for trimming or adjusting a sail by providing information about the airflow around the sail.  

Telltales on a sail

Tender is another word for dinghy.

Tiller is a rod used to move the rudder blade and control the direction of the boat. It is often used on smaller sailboats instead of a steering wheel. In case of an emergency, there might be a spare tiller onboard as a backup.

Topping lift  or topenant is a line that runs from the end of the boom to a point high on the mast, which supports the boom and prevents it from dropping too low when the mainsail is not raised.

Trade wind is a wind that blows steadily towards the equator from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere, usually found in tropical regions.

Transom is the reinforced vertical portion located at the stern of a boat. It connects the sides of the boat, giving it form and structure. The transom is also where an outboard motor is typically attached to the vessel and where the boat's name may be painted.

True wind is the actual wind that exists in the environment and is not affected by the motion of the body or the vessel. It is the wind that would be felt if the vessel were stationary.  Find out more in our article — Apparent vs. True Wind .

Sailboat facts for kids

A sailboat , sailing boat or yacht is a boat that has sails . Wind blows against the sails, pushing the boat through the water. The word covers many kinds of boats, from small sailboards to large sailing ships . Usually, a sailboat has two sails: a mainsail and a head sail or jib. When the wind blows from behind, there can be used an extra sail, a spinnaker.

Images for kids

Although sailboat terminology has varied across history, many terms have specific meanings in the context of modern yachting. A great number of sailboat-types may be distinguished by size, hull configuration, keel type, purpose, number and configuration of masts, and sail plan.

Popular monohull designs include:

The cutter is similar to a sloop with a single mast and mainsail, but generally carries the mast further aft to allow for a jib and staysail to be attached to the head stay and inner forestay, respectively. Once a common racing configuration, today it gives versatility to cruising boats, especially in allowing a small staysail to be flown from the inner stay in high winds.

A catboat has a single mast mounted far forward and does not carry a jib. Most modern designs have only one sail, the mainsail; however, the traditional catboat could carry multiple sails from the gaff rig.

A dinghy is a type of small open sailboat commonly used for recreation, sail training, and tending a larger vessel. They are popular in youth sailing programs for their short LOA , simple operation and minimal maintenance. They have three (or fewer) sails : the mainsail , jib , and spinnaker .

Ketches are similar to a sloop, but there is a second shorter mast astern of the mainmast, but forward of the rudder post. The second mast is called the mizzen mast and the sail is called the mizzen sail.

A schooner has a mainmast taller than its foremast , distinguishing it from a ketch or a yawl. A schooner can have more than two masts, with the foremast always lower than the foremost main. Traditional topsail schooners have topmasts allowing triangular topsails sails to be flown above their gaff sails; many modern schooners are Bermuda rigged.

The most common modern sailboat is the sloop, which features one mast and two sails, typically a Bermuda rigged main , and a headsail . This simple configuration is very efficient for sailing into the wind.

A fractional rigged sloop has its forestay attached at a point below the top of the mast, allowing the mainsail to be flattened to improve performance by raking the upper part of the mast aft by tensioning the backstay. A smaller headsail is easier for a short-handed crew to manage.

A yawl is similar to a ketch, with a shorter mizzen mast carried astern the rudderpost more for balancing the helm than propulsion.

Traditional sailboats are monohulls, but multi-hull catamarans and trimarans are gaining popularity. Monohull boats generally rely on ballast for stability. This creates two problems; one, it gives the monohull tremendous inertia, making it less maneuverable and reducing its acceleration. Secondly, unless it has been built with buoyant foam or air tanks, if a monohull fills with water, it will sink.

Multihulls rely on the geometry and the broad stance of their multiple hulls for their stability. Some multihulls are designed to be as light-weight as possible. They can be built with foam-filled flotation chambers and some modern trimarans are rated as unsinkable, meaning that, should every crew compartment be completely filled with water, the hull itself has sufficient buoyancy to remain afloat.

All vessels have a keel , it is the backbone of the hull. In traditional construction, it is the structure upon which all else depends.

Most modern monohull boats have fin keels, which are heavy and deep, but short in relation to the hull length. More traditional yachts carried a full keel which is generally half or more of the length of the boat. A recent feature is a winged keel, which is short and shallow, but carries a lot of weight in two "wings" which run sideways from the main part of the keel. Even more recent is the concept of canting keels, designed to move the weight at the bottom of a sailboat to the upwind side, allowing the boat to carry more sails.

Multihulls, on the other hand, have minimal need for such ballast, as they depend on the geometry of their design, the wide base of their multiple hulls, for their stability.

On small sailboats, masts may be "stepped" (put in place) with the bottom end in a receptacle that is supported above the keel of the boat or on the deck or other superstructure that allows the mast to be raised at a hinge point until it is erect. Some masts are supported solely at the keel and laterally at the deck and are called "unstayed". Most masts rely in part or entirely (for those stepped on the deck) on standing rigging, supporting them side-to-side and fore-and aft to hold them up. Masts over 25 feet (7.6 m) may require a crane and are typically stepped on the keel through any cabin or other superstructure.
