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.

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.The standard maritime radiotelephony pronunciation of the digit three. It is spoken as “TREE” when transmitting figures clearly by voice.

The International Code of Signals also has a numeral pennant for three, shown on…
The standard maritime radiotelephony pronunciation of the digit four. It is spoken as “FOW-er” when transmitting figures clearly by voice. The two-syllable form helps distinguish it in difficult reception conditions and does not mean a fourth officer or engineering rank. The International Code of Signals also has a numeral pennant for four, shown on this…
The standard maritime radiotelephony pronunciation of the digit five. It is spoken as “FIFE” when transmitting figures clearly by voice.

Farther towards the stern than a stated point or object on a vessel. It is a relative positional term: equipment abaft the mast lies on the stern side of the mast, while a compartment abaft the bridge lies behind the bridge in the vessel’s fore-and-aft orientation. Abaft does not necessarily mean at the stern and…
To become less intense or severe, especially when describing wind, sea or weather. A forecast, log or report may state that a gale, swell or storm is abating when its strength is decreasing. The word describes a trend rather than a particular force, wave height or rate of change. Abating conditions have not necessarily ended…
Directly to either side of a vessel, approximately at right angles to its fore-and-aft line. An object abeam bears about 090 degrees or 270 degrees relative to the vessel’s heading. “Abeam to port” and “abeam to starboard” identify the side on which it lies.
