We believe every day’s a school day on a boat! That’s why we built Nautical Know-How, dedicated to answering your questions. Even better, if it can’t answer your question immediately, you can request it, and we’ll add it to our knowledge base.
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.
The acquired ability to balance, move and work comfortably on a vessel in motion. Developing sea legs involves adapting posture, timing and movement to roll, pitch and acceleration and is separate from complete immunity to seasickness. Adaptation varies between people, vessels and conditions and can be lost after time ashore. Experience does not remove fall…
The coordinated use of personnel and facilities to locate people in distress, assist them and deliver them to a place of safety. Maritime SAR is organised through rescue coordination centres and sub-centres within agreed search-and-rescue regions and can involve coastguards, ships, aircraft, lifeboats, emergency services and other resources. The 1979 SAR Convention provides an international…
A tidal prediction location whose times and heights are obtained by applying published corrections to a standard port. Corrections may cover high- and low-water times and heights and can vary between springs and neaps or with the standard port’s predicted values. The exact method is publication-specific and may use interpolation rather than simple constant additions….
The international radiotelephony safety signal announcing an important navigational or meteorological warning or another safety message. The word is normally spoken three times, pronounced approximately ‘say-cure-ee-tay’, followed by the addressed station or all stations, the caller’s identity and the safety message under the applicable procedure. A digital selective calling safety announcement may precede voice traffic….
A vessel whose hull operates with substantial buoyant displacement support while also developing dynamic lift at higher speeds. Semi-displacement forms can exceed the practical speed range of a comparable pure displacement hull without achieving the low immersed volume and lift-dominated condition of a full planing craft. They often have flatter after sections, moderate length-to-beam ratios…
The forward impulse or surge imparted to a vessel or floating object by waves or swell. In traditional nautical usage, the send of the sea describes the bodily movement or momentum produced as a wave lifts and carries the vessel. It may be felt near a harbour entrance, shoal, wall or other place where wave…
To make an anchor dig into the seabed and develop holding resistance. After the anchor reaches the bottom and suitable rode is paid out, a gradually increasing load aligns it and encourages the flukes or body to penetrate. Setting is verified by observing position, transits, rode behaviour or other evidence while applying a load appropriate…
A removable load-bearing connector formed by a bow or body closed with a pin or bolt. Common marine types include D, bow, screw-pin and bolt-type shackles used in anchoring, mooring, lifting and rigging systems. Shape, material, pin type, working load limit and certification must suit the direction and nature of the load. Side loading, point…
A propulsion arrangement in which an inboard engine turns a propeller through a shaft passing through the hull. The system commonly includes a gearbox, coupling, shaft, bearings, stern tube, shaft seal or stuffing box, and an external propeller supported by a strut or stern bearing where required. Alignment carries engine torque while allowing the hull…
