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.
Buoyage FlashcardsFlashcards designed to help remember the buoys in the IALA system. If you want to learn them in detail, our module ‘Getting in and out of harbour‘, covers the IALA system and different buoys used.
Interactive Rule Book (COLREGs / IRPCS)Whether you’re a novice sailor or a seasoned skipper, we can help you navigate the IRPCS confidently and clearly. Our easy-to-use, easy-to-understand, plain English rule book with helpful interpretations of what each rule means.
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.The international radiotelephony spelling word for the letter V. It is used to spell call signs, identifiers and words clearly over voice radio. Its prescribed spoken form is represented as ‘VIK TAH’. The International Code of Signals assigns a separate meaning to the single flag V. That signal use should not be confused with saying…
The disturbed flow and wave pattern left behind a vessel or other body moving through water. A vessel’s wake can include divergent and transverse waves, propeller wash, turbulence and a region of changed current. Its size and persistence depend on speed, displacement, hull form, depth, channel width and propulsion rather than speed alone. Wake can…
A vertical or near-vertical post supporting guard wires, rails or other perimeter barriers aboard a vessel. Guardrail stanchions are seated in bases or sockets attached to the deck and transfer lateral loads into the structure. Other specialised posts aboard may also be called stanchions, so the guardrail context distinguishes this meaning. Bent posts, loose bases,…
A preparatory command telling the crew to get ready for an intended gybe. The warning allows crew to prepare sheets, preventers and other controls, check that the working area is clear and move away from the path of the boom and mainsheet. Crew should acknowledge when their stations are ready. It precedes the command or…
To remain or move away from a shore, vessel, hazard or position rather than approach it closely. The instruction can mean maintaining sea room, waiting clear of an entrance, increasing distance from danger or holding outside an operating area. It describes an intended relationship, not one fixed distance or manoeuvre. A safe stand-off distance depends…
To maintain course and speed as the stand-on vessel while monitoring an encounter and remaining ready to avoid collision. The requirement allows the give-way vessel to predict the stand-on vessel’s movement. The stand-on vessel may take action when it becomes apparent that the give-way vessel is not acting appropriately and must take action when collision…
A tidal reference location for which independent predictions of high- and low-water times and heights are published. A standard port provides the base data from which published corrections can be applied to associated secondary ports. The exact prediction method, time zone, datum, interval and available stream information depend on the responsible hydrographic publication. It is…
The relatively fixed stays, shrouds and associated fittings that support masts and other spars. Standing rigging commonly uses wire rope, rod or high-modulus fibre connected through terminals, turnbuckles and chainplates. It resists compression and bending loads in the mast and is distinguished from running rigging, which is routinely moved to hoist or control sails and…
The right-hand side of a vessel when facing forward. Starboard is fixed to the vessel and does not change with the observer’s facing direction. Its opposite is port, and the terms avoid the ambiguity of left and right when people aboard face different ways. At night the starboard sidelight is green and marks the prescribed…
The direction approximately at right angles to the vessel’s centreline on its starboard side. An object abeam to starboard has a relative bearing close to 090 degrees. In less precise speech, ‘on the starboard beam’ can refer to a small sector around that direction rather than exactly one bearing. The reference turns with the vessel…
