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.Lines forming part of a system that reduces and secures a sail’s exposed area. On slab-reefed mainsails, reefing lines commonly pull a reef clew towards the boom and may also control the reef tack in a single-line system. Traditional reef points secure bunt cloth after the primary tack and clew loads are taken, while roller…
A vessel restricted by the nature of its work in its ability to manoeuvre as required by the collision regulations and therefore unable to keep out of the way of another vessel. The definition applies to specified or comparable operations such as laying or servicing a navigation mark or cable, dredging, surveying, replenishment at sea,…
Any condition in which visibility is restricted by fog, mist, falling snow, heavy rainstorms, sandstorms or another similar cause. In the collision regulations this is a qualitative condition rather than one fixed distance. Darkness alone is not restricted visibility, although it affects what can be seen, and obstruction by a vessel’s own structure is a…
A path on the Earth’s surface that crosses every meridian at the same angle. A rhumb line represents a constant true course on an idealised surface and plots as a straight line on a Mercator chart. Except along a meridian or the Equator, it is generally longer than the corresponding great-circle route between two points….
A turn of rope trapped beneath or crossed by another loaded turn on a winch or drum. It forms when incoming rope overrides an earlier turn, often because of an unsuitable lead angle, slack handling or too many turns. Load then pinches the lower rope so it cannot run or be eased normally. A riding…
The system of spars, stays, shrouds, lines and fittings that supports and controls a vessel’s sails or other elevated equipment. Standing rigging primarily supports masts and resists relatively fixed loads, while running rigging moves or controls sails, spars and equipment. The term can include terminals, chainplates, blocks, tracks, winches and related hardware, and non-sailing vessels…
A lightweight powerboat with a rigid hull surrounded by inflatable buoyancy tubes. Commonly abbreviated to RIB, the design combines the shaped underwater form and structural support of a rigid hull with a large inflatable collar. The tubes add reserve buoyancy, provide a soft contact surface and contribute to stability, while the rigid hull supports the…
A situation in which the available information indicates that two vessels may collide unless appropriate action is taken. A steady or nearly steady compass bearing with decreasing range is a strong warning, but appreciable bearing change does not always remove risk when approaching a very large vessel, a tow or at close range. All available…
A system that stows a sail by rolling it around a stay, foil, spar or mandrel. Headsail furlers commonly rotate a foil or drum around the forestay, while mainsail systems can roll the sail inside a mast, inside a boom or around an external spar. A furling line or powered drive controls rotation while sheets…
Reducing a sail’s exposed area by partially rolling it around or into a stay, foil, mast or boom. Unlike complete roller furling, roller reefing leaves part of the sail set and loaded. Headsails roll around a stay or foil, while mainsails may roll inside a mast or boom or around a boom, and each arrangement…
