Nautical Terms

The front of a boat is the bow. The back is the stern. Everything towards the bow is 'forward' (or 'fore'), everything towards the stern is 'aft'. The midpoint is amidships.

The bow typically has a pointed shape to cut through waves. On a yacht the area at the front of the deck is called the foredeck. The stern may have a bathing platform or dinghy davits.

When facing forward, the left side of the boat is port and the right side is starboard. Port is associated with red (navigation lights, buoyage) and starboard with green.

A useful mnemonic: 'port' and 'left' both have four letters. Another: 'Is there any RED PORT LEFT in the bottle?'

The hull is the body of the boat. The waterline is where the hull meets the water surface. The draft (or draught) is the depth of the hull below the waterline — critical for knowing what depth of water you need.

The keel is the structural backbone running along the bottom of the hull. On sailing yachts, the keel extends downward to provide stability and resist sideways drift (leeway). The rudder, mounted at the stern, steers the boat and is controlled by a tiller or wheel.

The cockpit is the recessed area in the deck where the crew sit and the helm (tiller or wheel) is located. The companionway is the entrance/stairway leading below deck. Guardrails (or lifelines) run around the deck edge for safety, supported by stanchions.

Cleats are fittings used to secure ropes. A winch is a mechanical device for hauling ropes under load — essential for controlling sheets. A fairlead guides a rope in the desired direction. The pushpit is the guardrail frame at the stern, and the pulpit is the same at the bow.

The saloon is the main living area below deck. The galley is the kitchen. The heads is the toilet/bathroom. Berths are the sleeping areas — they may be in the forecabin (forward cabin), quarter berths (aft), or in the saloon itself.

The chart table is the navigation station where charts are plotted. Many modern yachts have electronic chart plotters here alongside traditional paper charts.

Standing rigging is the fixed wires that hold up the mast — shrouds run from the mast to the sides of the hull, the forestay runs forward, and the backstay runs aft. These are tensioned and rarely adjusted while sailing.

Running rigging is the ropes you actively use to control sails. A halyard hoists a sail up. A sheet controls the angle of a sail to the wind. The mainsheet controls the mainsail, the jib sheets control the headsail. The boom is the horizontal pole along the foot of the mainsail, controlled by the mainsheet and kicking strap (or vang).

Windward means towards the wind; leeward (pronounced 'loo-ard') means away from the wind. Ahead means in front of the vessel, astern means behind. Abeam means at right angles to the centreline.

A vessel's heading is the direction the bow points. Her course is the intended direction of travel. The track is the actual path over the ground (which may differ from the course due to tide and leeway). A bearing is the direction of an object measured from the vessel.

To make fast means to secure a rope. To cast off means to release the mooring lines and depart. Fenders are inflatable cushions hung over the side to protect the hull when alongside a pontoon or another vessel.

To tack is to turn the bow through the wind when sailing upwind. To gybe (or jibe) is to turn the stern through the wind when sailing downwind — this requires care as the boom can swing across violently.
