Important Sailing Terms For Beginners
We’ve all been there. In fact, sometimes I very much feel that I am still a beginner and I think any sailor that tells you they don’t have days where they feel like too is lying!
Sailing is ever-changing, and every situation is ever so slightly different. It’s one of the most wonderful things about sailing and one of the absolute worst!
But one thing is for sure, when you’re a beginner and being totally bombarded with sailing terms it’s really not helpful. You don’t need to know every single sailing term straight away. No matter what your crusty sailing instructor tells you!
There are however some really useful ones to learn straight away and these sailing terms will help you out a lot as you learn the ropes (or the lines, as us sailors like to say!) We’ve narrowed down the sailing terminology that we found essential when we started out sailing.
Focus on these for now and you’ll be amazed at how quickly the others become part of your everyday vocabulary as you learn to sail.
Aft: The back of the boat, or near the back of the boat. Aft basically means back!
Alongside: When the boat is next to a pier or another vessel.
Apparent wind: This is the wind that can be felt. It could refer to speed or direction, and is often different to the true wind. For example, if you are sailing forwards at 5 knts, the wind speed will feel stronger than if you are sitting still. The wind that can be felt is the apparent wind.
Astern: Behind the boat. Sailors often say ‘going astern’, which means going backwards or going in reverse.
Beam reach: A point of sail. When the wind is blowing perpendicular to the direction that you’re sailing.
Bearing away: Steering the boat away from the direction in which the wind is blowing.
Bilge: This is the bottom of the inside of the boat. Water collects in the bilge, and then you use a bilge pump to pump the water overboard. Many people store things in their bilge for longer passages.
Boom: This is the long pole that sticks out of the mast. It holds the bottom of the mainsail in place and can be moved from side to side depending on where the wind is coming from. Booms can be very dangerous, as they are heavy and tend to carry a lot of power when the sail is full of wind.
Bow: The front of the boat.
Broad reach: A point of sail. Sailing with the wind coming off your stern quarter, a position in between the beam and stern of the boat.
Cleats: The metal blocks to which you secure lines.
Close-hauled: A point of sail. Sailing as close to the wind as possible without the sails flapping. On a monohull, the boat will usually heel over the most on this point of sail.
Close Reach: A point of sail. When you’re sailing between a beam reach and close hauled. Again, as you are travelling towards to wind on this point of sail it is likely the boat will be heeled over.
Dead run or Running Dead Downwind: A point of sail. Sailing with the wind coming from directly behind the boat. Many people use a light wind sail to catch the wind if the conditions are right, or pole out a sail to be ‘wing on wing’ and catch as much of the wind as possible.
Draft: The depth of a boat when it’s sitting in the water.
Fender: An inflated bumper used to keep the boat from banging into the dock or another boat.
Genoa: A large forward sail that comes back past the mast when fully unfurled. It is the same as a job sail but larger.
Heave to: A sailing manouvre used mostly during storms, which lies the boat favourably to waves while making only very slight headway.
Jib: A triangular forward sail, smaller than a genoa.
Jibing: When you steer the boat downwind from one direction to the other to keep the sails full. As you move from one direction to the other the wind will come from a different side and the sails will need to be moved across the boat to keep them powered up. It is similar to tacking, but going downwind instead of up! There is more danger from the boom when jibing.
Mainsail: The main sail on the boat, attached to the mast.
Mayday: The emergency call you make over the radio to show the boat or crew are in distress and needs immediate assistance.
No-sail zone: Also called the dead zone. This is an area 45 degrees either side of directly into the wind. This is the area a boat can’t sail in, and your sails will flap and the boat will power down if you try.
Port: The left side of the boat when facing forward.
Reef: When you lower some of the sail to give less sail area to the wind, usually done as the wind speed picks up.
Sheet: A line or rope used to control the trim of a sail.
Starboard: The right side of the boat when facing forward.
Stern: The back end of the boat.
Tacking: Turning the boat into the wind to change direction. You will pass through the dead zone quickly, adjusting the sails to the other side of the boat so you can continue to sail towards the wind in a zig-zag type shape.
Topping lift: A rope running from the back end of the boom to the top of the mast. This line controls the height of the boom and prevents it from falling when the sail isn’t raised.
Winch: A mechanical device used to pull the lines that control sails.
Windlass: A winch used to raise and lower the anchor.
Most of the terms below you can muddle by without knowing and pick them up as you go.
A lot of them are just fancy terms for things you probably just use a different name for in every day life, and while they’re useful to have in your sailing vocabulary they can be communicated in other ways, or picked up as and when is necessary!
Sailing Terms: A Complete Guide
Here is a more comprehensive guide to different sailing terms. Feel free to look through them and start to get familiar with them if you’re a new sailor, but don’t let them overwhelm you! You will pick them up the more time you spend on the water and around other sailors.
Abeam: Anything to the side of your boat. If you spot a vessel beside you, you can say it is abeam, and people will know to look out at 90 degrees from the centreline of your boat.
Abaft: Towards the back of the boat. Anything abaft means towards the stern, so the life ring is abaft the mast, meaning the opposite of forward or the mast. It could also mean something behind the boat, like rocks or another vessel.
Abandon ship: A command given to leave the boat immediately. Usually given by the captain when the boat and crew are in serious danger.
Adrift: Unattached to the sea bed. It usually means a vessel that isn’t anchored and not under control, so free to float around where ever the wind blows.
Aft: The back of the boat, or near the back of the boat. Aft basically means back!
Aground: Resting on or touching the ground or bottom. This usually applies to a ship that has run aground, and is now stuck on the sea floor.
Alongside: When the boat is next to a pier or another vessel.
Anchor: A heavy piece of specially shaped metal that keeps the boat secured to the ground.
Apparent wind: This is the wind that can be felt. It could refer to speed or direction, and is often different to the true wind. For example, if you are sailing forwards at 5 knts, the wind speed will feel stronger than if you are sitting still. The wind that can be felt is the apparent wind.
Astern: Behind the boat. Sailors often say ‘going astern’, which means going backwards or going in reverse.
Athwartship: The position across a vessel from side to side at right angles to the keel.
Backing (a sail): Forcing the wind into the ‘wrong’ side of the sail by pulling it to the opposite side of the boat.
Backstay: The wire that runs from the back of the boat up to the top of the mast to stop it from falling forward. The backstay is often thicker and stronger than the other stays.
Bailer: A scoop that is used to collect water from the bottom of a vessel. It can be any container! You’ll want one in your grab bag for if you ever need to bail water from a life raft or a dinghy.
Ballast: Weight to add stability to your vessel. The weight is usually lead or iron and can often be found within the keel of the boat. Some boats add extra ballast for more stability.
Batten: A thin strip of fiberglass (usually) that slots into pockets of the mainsail to help it maintain an open shape. Battens run from the back edge of the sail, the leech, to the forward edge of the sail, the luff. Most will have more than one batten, but not all mainsails have battens.
Beam: The widest point of the boat.
Beam reach: A point of sail. When the wind is blowing perpendicular to the direction that you’re sailing.
Bearing away: Steering the boat away from the direction in which the wind is blowing.
Bend: A knot used to connect two ropes.
Berth: Berth has several meanings. It could be your bed onboard, or it could be your slip in a marina.
Bight: A bend in a rope or line. When a rope forms a bight, it has changed direction 180 degrees.
Bilge: This is the bottom of the inside of the boat. Water collects in the bilge, and then you use a bilge pump to pump the water overboard. Many people store things in their bilge for longer passages.
Bimini: The cover over the cockpit. Usually this is made from canvas and can be removed. It shades from the sun and offers a little protection from the rain.
Binnacle: The pedestal centrally located in the cockpit. It usually holds the steering wheel along with navigational equipment like your chart plotter and compass.
Bitter end: The last part of a rope or cable, usually referring to the anchor chain. Once the chain or rope has been paid out completely it has reached its bitter end.
Block: A pulley.
Boom: This is the long pole that sticks out of the mast. It holds the bottom of the mainsail in place and can be moved from side to side depending on where the wind is coming from. Booms can be very dangerous, as they are heavy and tend to carry a lot of power when the sail is full of wind.
Boom vang: This prevents the boom and mainsail from moving upwards which sailing. It pulls the boom down to help the mainsail keep the right shape.
Boot Top or Boot Stripe: The paint between the boat’s bottom paint and it’s topside paint. It’s usually a white stripe that runs around the boat.
Bow: The front of the boat.
Bowsprit: A section of the boat that runs even further forward than the bow. It looks like a small diving board sticking out the front of the boat. Not all boats have a bowsprit and they are more common on classic boats. They allow the rigging to be attached further forward.
Broach: When a boat sailing downwind accidentally ends up sideways to the waves and heels over dangerously. This is usually caused by large waves that force the boat to travel too fast and end up in a position beam on to the waves.
Broad reach: A point of sail. Sailing with the wind coming off your stern quarter, a position in between the beam and stern of the boat.
Bulkhead: The walls in a boat that run across the centerline of the vessel. These are structurally important and mustn’t be messed with!
Capsize: When a vessel tips over past 90 degrees.
Catamaran: A vessel with two hulls.
Centerboard: A keel that can lift up and down depending on the point of sail. It helps the boat to point further to wind when down, or run more easily downwind when raised. When raised, the boat can sneak into shallower waters.
Centerline: An imaginary line that runs all the way from the center of the bow to the center of the stern.
Chainplate: A metal plate attached to the hull of the boat, which the rigging is attached to. Chainplates are very important to hold the mast upright, and must be well maintained. Some are visible on the exterior and others are hidden on the interior.
Chandlery: A store that sells boat supplies.
Cleats: The metal blocks to which you secure lines.
Chock: A fitting that a line passes through to change direction without chafing.
Clew: The lower back corner of a sail, where the foot and leech of the sail meet.
Close-hauled: A point of sail. Sailing as close to the wind as possible without the sails flapping. On a monohull, the boat will usually heel over the most on this point of sail.
Close Reach: A point of sail. When you’re sailing between a beam reach and close hauled. Again, as you are travelling towards to wind on this point of sail it is likely the boat will be heeled over.
Coamings: A area around the cockpit or hatches that is designed to keep out water.
Cockpit: The area where the helm of the boat is. It is usually where there is seating, and the entrance to the interior of the boat. Cockpits can be at the stern of the boat or in the centre. Some sailors prefer a centre cockpit for a feeling of safety, others prefer the extra space you get with an aft cockpit.
Companionway: The entrance into the interior of the vessel.
Cotter pin: A bendable metal pin that you fit into a metal rod and then bend back to lock. You will find these most commonly on the rigging.
Daybeacons: Markers for navigation that are on posts. These are red (port) or green (starboard).
Dead run or Running Dead Downwind: A point of sail. Sailing with the wind coming from directly behind the boat. Many people use a light wind sail to catch the wind if the conditions are right, or pole out a sail to be ‘wing on wing’ and catch as much of the wind as possible.
Dead reckoning: Determining a vessel’s position by knowing the direction and speed traveled.
Dinghy: The small, usually inflatable boat that you use to reach the shore when your big boat is at anchor. These are also called tenders.
Dodger: This is like the windshield of the boat. It’s a structure at the front of the cockpit to protect the helmsman from wind or spray.
Dismasting: When the mast breaks off. This usually happens because of a rigging failure, or can happen if the rig is overpowered.
Displacement: The weight of the water that would otherwise be in the place of the boat’s hull.
Drogue: A sea anchor to help slow down the boat. You might use one in big seas when the boat is sailing too fast down the waves. It can look like a small parachute on a line that you hang off the back of a boat, or even just a line or several lines hanging from the stern can help to slow the boat down.
Ebb tide: After high tide when the water is receding towards low tide.
EPIRB: Emergency Position Indicating Radio Beacon. This device transmits a distress signal to alert emergency services to the position of a vessel in trouble. Most people carry an EPRIB in their grab bag, or an easy to reach place in the boat.
Fairlead: A fitting which ensures a line runs in the right direction without snagging on anything.
Fathom: A measurement of water depth equal to 6 feet, not used very often anymore!
Fender: An inflated bumper used to keep the boat from banging into the dock or another boat.
Fid: A tool used for splicing a line.
Fiddle: The raised edge around a table to prevent things from falling off in a seaway.
Fix: Determining a vessel’s location by using the compass bearing of two or more fixed points of reference. You will usually use this to check the boat isn’t dragging when anchored.
Fin keel: A fixed keel that hangs below the boat to provide stability.
Flogging: When a sail flaps noisily in the wind because it is not being filled properly. This usually happens when the boat is trying to sail too close to the wind.
Flood tide: The time between low tide and high tide when the water is rising.
Following sea: Waves or tidal movement going in the same direction as the boat.
Foot: The bottom edge of a sail.
Fore: At or near the bow (front) of a vessel.
Forestay: The rigging wire which goes from the bow to the top of the mast. This is where the foresail is attached, either hanked on or using a roller furling system. Most modern boats use a furling system as it is easier and quicker to use.
Full keel: A fixed, ballasted keel running the whole length of the boat.
Furling system: The system used to roll up a sail when it’s not in use and unfurl it when it is. It is most common to find furling foresails but in mast furling for the mainsail has also become more popular over recent years.
Freeboard: The distance on a vessel from the waterline to the deck.
Galley: The kitchen!
Gelcoat: The paint used on the outside of a boat. It’s a tough resin that forms a protective coating.
Genoa: A large forward sail that comes back past the mast when fully unfurled. It is the same as a job sail but larger.
Gimbals: You will usually find these on your galley stove. They make your oven act a little like a rocking crib, so that it can stay level even when the boat is heeling or rocking. This is essential for keeping things on the stove while sailing or in a rolly anchorage.
Gooseneck: The point at which the boom attaches to the mast, letting the boom move freely from side to side and up and down. You then use lines to control it!
Ground tackle: The anchor, chain, and line that you use for anchoring or fixing the boat to the bottom of the sea when you want to stop and stay put.
Gunwale: The top edge of a boat’s hull.
Halyard: The line which attaches to a sail to raise it.
Hanks: The clips that attach the front edge of a sail to the forestay. It is more common these days to use a furling system for your main forestay, so you will likely only see these on a storm sail.
Hatch: A window in the ‘roof’ of the sailboat. It opens out onto the deck.
Head: The bathroom on a boat.
Headway: The amount you’re moving forward through the water. Like ‘making headway’.
Heave to: A way to keep the boat from moving through the water with minimal drift, usually used in heavy, dangerous seas. You back the foresail but lock the helm hard over towards the wind. Your boat should sit nicely creating a slick over breaking waves and you should only drift a little through the water. Not all boats will heave to nicely, so you should test this method with your vessel.
Heel: The tilt of a sailboat that usually happens when you’re sailing towards the wind.
In-Irons: When you steer the boat into the wind (by accident or on purpose) and the sails lose power. The boat will lose steerage as it slows down.
Jackline or Jackstay: Safety lines that run from the bow to the stern. You can clip yourself onto these lines so that you don’t fall overboard when doing tasks that require you to leave the cockpit.
Jib: A triangular forward sail, smaller than a genoa.
Jib sheets: The lines you use to control the jib.
Jibing: When you steer the boat downwind from one direction to the other to keep the sails full. As you move from one direction to the other the wind will come from a different side and the sails will need to be moved across the boat to keep them powered up. It is similar to tacking, but going downwind instead of up! There is more danger from the boom when jibing.
Kedge anchor: A small, lighter second anchor that you can use as a back up or a stern anchor.
Keel: The bottom of the boat.
Ketch: A sailboat with two masts, where the forward mast is the taller mast.
Knot: Usually referring to speed when sailing rather than the knots you tie in a line. One knot is equal to one nautical mile per hour.
Lazyjacks: Thin lines that run from the boom to the mast to help control the mainsail when it’s lowered.
Leech: The back edge of a sail.
Lee shore: The shore onto which the wind is blowing. This is the side of an island you want to avoid anchoring on, as it will mean the wind is blowing directly into the anchorage.
Leeward: The direction the wind is blowing towards. So if the wind is blowing from the north then the south is leeward.
Liveaboard: Someone who lives full time, or the majority of the time, on board their boat
Luff: The forward edge of the sail.
Mast: The tall pointy thing that holds up the sails!
Mainsail: The main sail on the boat, attached to the mast.
Mayday: The emergency call you make over the radio to show the boat or crew are in distress and needs immediate assistance.
Mizzen: The shorter mast behind the main mast on a ketch.
Monohull: A boat with a single hull.
Mooring field: An anchorage full of permanently attached buoys, to which you can moor up your boat.
Multihull: A vessel with more than one hull like a catamaran or trimaran.
No-sail zone: Also called the dead zone. This is an area 45 degrees either side of directly into the wind. This is the area a boat can’t sail in, and your sails will flap and the boat will power down if you try.
On the hard: When your boat is out of the water, usually in a boat yard.
Painter: The line which attaches your dinghy to your main boat.
Pan Pan: This is a distress call that isn’t quite as urgent as a Mayday call. You will put out a pan pan on the radio if your boat needs assistance or you want to alert the emergency services of a problem that might get worse and become a mayday. For example, you have lost your engine and will drift into rocks if you can’t solve the problem or the wind doesn’t pick up in time.
Points of sail: The way your boat is travelling in relation to the wind.
Port: The left side of the boat when facing forward.
Port tack: Sailing with the wind hitting the port side of the vessel.
Pulpit: The metal rails at the bow of the boat.
Pushpit: The metal rails at the back of the boat.
Quarter: The back corner area of the boat.
Reef: Reefing the sails is when you lower some of the sail to give less sail area to the wind, usually done as the wind speed picks up.
Rigging: All the wires and ropes used to hold the mast in place and adjust the sails.
Roach: The curved shape of the rearmost edge of a triangular sail.
Roller furling: The system that rolls up the sails to store them when they’re not in use.
Rudder: The thing that controls the direction of the boat. This is usually a fin at the stern of the boat under the water line and behind the propeller. It’s controlled by a steering wheel or tiller from the cockpit.
Running: Sailing downwind.
Running rigging: The lines which control the sails.
Schooner: A sailboat with two or more masts. The mainmast is at the back.
Seacock: A valve that can be opened or closed to control the flow of water in or out of the boat.
Scope: The length of chain between the anchor and the boat.
Scuppers: Deck drains to allow water to flow overboard when it rains or when crash onto the cockpit.
Securite: A call transmitted over the radio to alert sailors to potential dangers in their area.
Shackle: A metal U or D shaped link with a removable pin that can be used to attach lines to blocks and other useful things like that!
Sheet: A line or rope used to control the trim of a sail.
Shrouds: Wires or ropes running from the chainplates to the mast to stop the mast moving from side to side.
Skeg: An extension of the hull hanging in front of the rudder, that the rudder is attached to. It can help protect the rudder from getting hit or from debris in the sea.
Sloop: A single masted sailboat with a mainsail and one foresail.
Slugs: The things that the mainsail sits in to run it up the boom.
Spinnaker: A sail used for light, downwind sail. Spinnakers are often the biggest sail on the boat, made from a light material and they are often brightly coloured.
Splice: When you connect two lines together using their weave. You will often need a fid for this.
Spreaders: The horizontal poles that come out from the sides of the mast.
Spring line: These are used when docking the boat. They are the lines that come from the bow or the stern to a point midship on the dock. They are used to control how far the boat can move forwards and backwards while in its slip.
Stanchions: The metal posts along the outside of the deck through which the lifelines run.
Standing rigging: The wires and ropes, such as the shrouds and stays, that are permanently in place and hold up the mast.
Starboard: The right side of the boat when facing forward.
Starboard tack: Sailing with the wind hitting the starboard side of the boat.
Stays: The wires or ropes running from the bow and stern to stop the mast moving forwards or backwards.
Stern: The back end of the boat.
Storm jib: A small foresail that can be hanked on during heavy weather. It is made from tough, heavy material and often brightly coloured.
Tack: The forward lower corner of a sail.
Tacking: Turning the boat into the wind to change direction. You will pass through the dead zone quickly, adjusting the sails to the other side of the boat so you can continue to sail towards the wind in a zig-zag type shape.
Tender: The same as a dinghy. A small boat, usually inflatable, that you use to get to shore when the boat is anchored.
Tiller: A bar used to control the rudder from the cockpit. It is the same as a steering wheel, but some prefer using a rudder, or find it takes up less space in the cockpit.
Toe rail: The raised lip around the edge of the deck that helps stops things falling overboard.
Topping lift: A rope running from the back end of the boom to the top of the mast. This line controls the height of the boom and prevents it from falling when the sail isn’t raised.
Trim: Adjusting the shape and angle of the sails to get optimum performance.
Watermaker: A device used on board sailboats to make fresh drinkable water from the sea.
Weather helm: If the helm was centered, the boat would turn towards the wind (weather). Because of this, the tiller must be pulled to the windward side of the boat in order to make the boat sail in a straight line.
Winch: A mechanical device used to pull the lines that control sails.
Windlass: A winch used to raise and lower the anchor.
Windward: The direction from which the wind is blowing.
Wing on wing: Sailing downwind with the foresail and the mainsail out on different sides of the boat to catch as much of the wind as possible.
