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.
Nautical Terms & TerminologyUnderstanding the language of the marine world is like trying to learn a pirate’s secret code while juggling fish. 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.
Why do we have tides?Have you ever wondered what causes the tides? Check out this video, which introduces the forces that create the tides we experience on Earth.
What causes our weather?A video introducing the drivers behind our weather, part of our RYA Day Skipper & RYA Coastal Skipper / Yachtmaster® Offshore theory courses.

The Salty Sea BlogFrom salty old sea dogs to fresh-faced deckhands, this blog is for anyone who finds peace, adventure, and a bit of mischief on the water. So hoist the main, set your course, and let’s sail into the stories, lessons, and musings that make life on the sea so irresistible.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 international radiotelephony spelling word for the letter R. It is used to spell call signs, identifiers and words clearly over voice radio. Its prescribed spoken form is represented as ‘ROW ME OH’. In the International Code of Signals, the single flag R can have coded meanings in combination with other flags. Those signal meanings…
For a sailing vessel to turn rapidly or unintentionally towards the wind. A round-up commonly occurs when heel, rudder load or weather helm exceeds the available steering control, particularly in a gust or with excessive sail. The sails may luff and the vessel may slow sharply or pass through the wind. Reducing heel and restoring…
A portable fender kept ready to be positioned where unexpected contact is likely. It supplements fenders already rigged for berthing or rafting and can be moved to a changing contact point between vessels, a quay, pile or lock wall. A crew member may control it by a line, but should not use hands or feet…
A steering surface that produces a turning force by deflecting water flowing past it. A rudder may be hung on the stern, supported by a skeg, balanced around a stock, mounted as a spade or incorporated into other arrangements. It works only when there is sufficient relative water flow, which can come from vessel movement…
The strong shaft that supports a rudder and transmits steering movement to it. The rudder stock passes into or through the hull and connects the rudder blade to a tiller, quadrant, steering arm or other steering mechanism. Bearings support and guide the stock, while a gland, seal or tube limits water entry where the arrangement…
To allow a line, chain or cable to move through its lead or controlling equipment. A line may be ordered to run freely or under controlled rendering, depending on the operation. The word can also describe how a line is routed, as in running it through a block, so crew instructions should make the intended…
A position fix obtained by advancing an earlier line of position to the time of a later observation. It is commonly used when the same charted object is observed twice from a moving vessel, but observations of different objects or other lines of position can also be combined. The earlier line is transferred by the…
Lines, wire and associated movable equipment used to hoist, lower, trim or control sails, spars and other gear. Halyards, sheets, guys, lifts, reefing lines and control lines are typical examples, working through blocks, sheaves, tracks, clutches, cleats and winches. Unlike standing rigging, these components move or are adjusted during operation, although some remain loaded for…
A deliberately reactive metal component that corrodes in preference to protected underwater metalwork. The anode is electrically connected to the metal it protects, such as a propeller, shaft, stern gear, drive unit or bonded fitting. Zinc, aluminium and magnesium alloys are used in different environments and systems; the correct material depends on water type, protected…
A navigation mark indicating navigable water around the mark. Under the IALA Maritime Buoyage System, a safe water mark has red-and-white vertical stripes and, when fitted, a single red spherical topmark. Its white light uses one of the characteristics allocated to this type of mark. It may mark a channel centreline, mid-channel point, landfall or…
