Understanding the language of the marine world is like trying to learn a pirate’s secret code while juggling fish. You’ll wonder why a “sheet” isn’t something you sleep under but a rope that controls a sail. “Bowsprit” sounds like a sneeze, “booby hatch” isn’t a bird’s hideout, and “port” doesn’t come in a glass—it’s just left. If someone yells, “Man overboard!” don’t ask which direction they swam. And heaven help you if you think “scuttlebutt” is gossip—well, actually, you’d be right about that one. By the time you’ve figured out that “head” means toilet and “galley” isn’t an alley with gourds, you’ve already been hit with a wave and lost your hat to the wind they call a “nor’easter.”
Let us explain why a sheet isn’t for your bed, why “heave ho” doesn’t mean throw up (most of the time), and why “dead reckoning” is surprisingly less ominous than it sounds.
To secure a line or object so that it remains held in the required position. A line may be made fast to a cleat, bollard, bitt, samson post or other suitable fitting using the appropriate turns, hitch, splice or hardware. The instruction can also apply to securing a vessel, fender, tender or item of equipment….
Moving through the water rather than merely moving over the ground with the surrounding water. A vessel may be making way under engine, sail, oars, tow or another means; the expression does not require its own propulsion. Conversely, a vessel drifting with a current can move over the ground while making little or no way…

A nine-digit identity transmitted by maritime radio systems to identify a ship, coast station, group or other assigned station type. MMSIs are used by systems including digital selective calling and AIS. Their digit patterns vary by identity type; a ship-station MMSI normally begins with three Maritime Identification Digits identifying the responsible administration, while coast, group,…
A principal upright or near-upright spar or structure that supports sails, rigging or equipment aboard a vessel. A sailing mast carries sail and rig loads through standing and running rigging and may be deck-stepped or keel-stepped. Power vessels also use masts for lights, antennas, radar, signals and sensors, and construction may be timber, aluminium, steel…
The structural fitting or support on which the heel of a mast is seated. A mast step locates the base of the mast and transfers compression and other rig loads into the vessel’s structure. It may be on deck, on the coachroof or lower in the hull for a keel-stepped mast, and its form must…
A white navigation light showing over the forward sector of a vessel. Despite its name, a masthead light need not be positioned at the physical top of a mast. It is carried over the vessel’s fore-and-aft centreline and shows from directly ahead to a specified distance abaft the beam on each side. It forms part…
The spoken radiotelephony distress signal indicating grave and imminent danger and a need for immediate assistance. Mayday is used for emergencies such as a vessel sinking, a serious fire or an immediate threat to life. The word derives from the French expression m’aidez, meaning “help me”, and is normally spoken three times at the start…
The average height of the two successive high waters during spring-tide periods at a stated location and over a defined observation period.
