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.A folding or fixed canopy over a companionway or forward cockpit area that deflects spray, wind and rain. Often called a dodger in North American usage, it normally consists of fabric and transparent panels supported by a metal frame. Its coverage, handholds, windows and ability to fold vary, and it may connect to a cockpit…
A compression strut projecting from a mast to deflect and support a shroud or stay. Spreaders increase the angle between mast and rigging so shroud tension can support the mast more effectively. They may be straight or swept, fixed or articulated, and arranged in one or several sets according to the rig. Their roots, tips,…
Mooring lines led diagonally to limit a vessel’s forward or aft movement alongside. A forward spring and an aft spring oppose movement in opposite directions. Their names describe where they lead and the movement they control rather than simply the end of the vessel from which they are handled, so terminology should be agreed clearly…
A sudden, substantial increase in wind speed that lasts longer than a brief gust. A squall can accompany a shower, thunderstorm, cold front or line of convective cloud, but it is not defined by the presence of dark cloud or by one particular type of front. Wind direction may shift and heavy rain, hail, lightning…
An inclined prepared surface leading between land and water for launching, recovering or building vessels. A slipway may be a simple ramp for trailers, a railed cradle system or a large construction berth. Gradient, surface, tidal access, depth, turning space, load limit and permitted users determine which vessels and equipment can use it. Algae, mud,…
A sudden shock load caused when slack in a line is taken up abruptly. An anchor, mooring or towing line can snatch when vessel movement alternately slackens and then jerks it tight. Inadequate scope, little elasticity, waves and poor lead can increase the load on the line, fittings and vessel. In a separate verb use,…
To secure a vessel, its rig and loose equipment in a compact, protected condition for heavy weather, harbour or inactivity. The expression can include reducing or stowing sails, lashing booms and movable gear, closing openings, securing lockers and preparing moorings, anchors or storm equipment. The actions depend on whether the vessel is under way, at…
Removable or fixed panels forming part of the walking surface inside a vessel. They commonly cover bilges, tanks, structure or service runs and may provide inspection access through lifted panels or separate hatches. Marine plywood, timber, composite or metal panels can be used, often with a non-slip finish. Boards must be supported and secured against…
A waterproof hat with a broad brim shaped to protect the face and neck from rain and spray. The rear brim is longer so that water runs clear of the collar, while the front and side brim gives protection without obstructing vision excessively. Traditional versions were made from oiled fabric; modern examples commonly use coated…
A long structural member used to support, extend or control sails, rigging, signals or equipment aboard a vessel. Masts, booms, yards, gaffs, bowsprits, spinnaker poles and whisker poles are spars. They may be timber, aluminium, steel or composite and carry compression, bending, torsion and local loads through fittings and rigging. A spar’s section, support and…
