Abeam: At right angles to the centerline of the boat.
Aboard: On or in a boat.
Aft: Near the stern, towards the stern.
Amidships: In the middle of the boat.
Apparent Wind: Wind felt when moving. Combination of the true wind and wind created by motion through the air.
Astern: Behind the stern of a boat.
Backstay: Rigging that supports the mast from the back of the boat. Typically a wire rope or metal rod connected to the top of the mast and the stern of the boat.
Battens: Thin, rigid strips placed in a pocket in the leech of a sail to help shape the sail more efficiently. Typically made of wood, metal, or plastics.
Beam: The width of a boat at its widest point.
Beam Reach: The point of sail on which the boat sails perpendicular to the wind.
Bearing: The direction from one position or object to another.
Beat: To sail on a close-hauled point of sail.
Belay: To secure a line.
Ballast: Any weight used to increase the stability of a boat.
Block: A nautical name for a pulley.
Bolt Rope: Rope sewn into the side of a sail to give it strength and to facilitate attaching that side of the sail to the boat.
Boom: The horizontal spar or pole which attaches to the mast and extends aft. Used to control the shape and position of the mainsail.
Boom Vang: A block and tackle system, running from the boom to the bottom of the mast, which prevents the boom from lifting as the sail fills with wind.
Bow: Forward part of the boat.
Broad Reach: The point of sail where the wind crosses one of the back quarters of the boat.
Capsize: To turn a boat on its side or upside down to the point where it will not right itself.
Cast Off: To release or let go of a line.
Centerboard: A thin board which pivots down into the water. Provides minimal stability to the boat and prevents leeway.
Centerboard Trunk: A slot in the hull through which the centerboard pivots up and down.
Cleat: A device or fitting which secures and holds the tension on a line.
Clew: The lower, rear corner of triangular and quadrilateral sails. Or, the lower, “free” corners of a square sail.

Close Reach: The second most windward point of sail. A windward course that is not as close to the wind as close-hauled.
Cringle: A hole through a sail or thin material through which lines can pass. Cringles are typically reinforced with a grommet.
Course: The direction or path a boat is taking.
Cunningham: A special type of downhaul which passes through a cringle slightly above the tack of a sail and secured to the mast. Applies downward force on the sail tensioning the luff.
Daggerboard: Similar to a centerboard in purpose and functionality. The difference being that a centerboard pivots up and down, whereas a daggerboard slides vertically up and down.
Downhaul: A line, or block and tackle system, attached to a spar or sail which applies downward force.
Eye of the Wind: The precise direction from which the wind is coming from.
Fairlead: A fitting or device used to change the direction of a line to provide a better angle to a sail, winch, block, or cleat. Typically found on sheets before the cleat.

Furl: To fold or roll up a sail.
Give Way: To allow another vessel right of way.
Gooseneck: A fitting connecting the boom to the mast.
Grommet: A ring placed around a hole through a thin material. Provides structural support around the hole, and prevents tearing or abrasions of the material. In boating, it is most commonly seen reinforcing a cringle.

Knot (in a line): A method of bending a line around itself to serve a function. Stopper knots, for example, are formations in a line that prevent the line from going through a fitting.
Knot (unit of speed): A common nautical unit of speed. 1 knot = 1 nautical mile per hour = 1.15 miles per hour.
Lee: A common shorthand word used in place of leeward. See leeward.
Leech: The back edge of a triangular or quadrilateral sail. The two vertical sides of a square sail.
Leeward: Nautical term meaning downwind or away from the wind.

Wing and Wing: Sailing the boat downwind on a run with sails set on opposite sides.
Wing on Wing: Less commonly used saying meaning the same as wing and wing.
There are three distinct methods of tying ropes. A ” knot ” is a formation of rope around itself. A formation of rope used to join two separate ones together is called a ” bend,” and, a formation of rope used to attach a rope to another object such as a cleat, mooring, or pole, is a ” hitch.“ However, in general conversation, it is common to reference all three simply as knots.
“Line” versus “Rope”
In boating, what is colloquially known as ropes are referred to as lines with very few exceptions. While working near or operating boats, you should typically avoid the use of the word rope and substitute line instead. The difference between the two terms is subtle, but the word rope refers to the general, manufactured material. Whereas line refers to a piece of rope purposefully sized, cut, spliced, or simply assigned a function; making line a marginally more specific term.
