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.A bow fitting with one or more rollers that supports and guides an anchor and its rode during handling. The roller reduces friction and helps lead chain or rope between the water, windlass and stowage position. Its geometry must suit the anchor so that the anchor launches, returns and nests without damaging the stem, pulpit…
A place where vessels anchor or may anchor. An anchorage may be officially designated and charted or simply a location selected by a mariner. It may serve leisure craft, ships awaiting a berth, quarantine or other operational needs, and it is not necessarily sheltered or provided with good holding ground. Selection requires assessment of depth…
A coating applied to a vessel’s underwater surfaces to prevent or reduce the attachment of marine organisms. Marine growth such as slime, algae and molluscs increases resistance through the water, reducing speed and increasing fuel or energy use. Antifouling systems include biocidal paints and non-biocidal coatings or surface treatments. Products must be suitable for the…
A VHF-based system that automatically exchanges vessel identity, position and movement data. Commonly abbreviated to AIS, it transmits dynamic information such as position, course and speed together with entered or programmed information such as identity, vessel type and voyage details. Compatible vessels, shore stations and aids to navigation can receive and display those reports. AIS…
A secondary machine, system or service that supports a vessel’s primary operation. On a sailing vessel, “the auxiliary” commonly means an engine providing propulsion when sails are unsuitable or additional control is needed. On other vessels, auxiliary machinery includes generators, pumps, compressors, thrusters and systems serving functions other than the main propulsion plant. Auxiliary does…
Standing rigging leading aft from a mast to support it against forward loads. A permanent backstay commonly leads from or near the masthead to the stern area. On some rigs its tension can be adjusted to control forestay tension and mast bend, affecting headsail shape and mainsail trim. Not every sailing rig has a fixed…
To remove water from inside a boat using a bucket, scoop or similar container. Bailing is common in dinghies, tenders and open boats after rain, spray, a capsize or water shipped over the side. A hand bailer may also supplement a pump or self-bailer when water accumulates faster than the installed system removes it. Removing…
A container or fitted device used to remove water from a boat. A hand bailer may be a purpose-made scoop, bucket or other suitable container. Some small craft also have self-bailers that use the boat’s movement through the water to drain water from the hull. A manual bailer remains useful when pumps or automatic drainage…
Weight carried or built into a vessel to improve stability, trim or draught. Ballast may be fixed, as in a sailing yacht’s keel, or variable, such as water held in ballast tanks. Its position is as important as its mass: low ballast generally increases resistance to heeling, while poorly positioned or shifting weight can adversely…
The condition of a sailing vessel when all sails are lowered or stowed. Even without sails set, wind acting on the hull, mast and rigging can continue to drive the vessel through the water or cause it to drift. Sailing under bare poles is principally associated with severe-weather tactics, but the vessel’s behaviour depends on…
