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.An overlapping headsail whose clew extends abaft the mast when sheeted. Genoa size is conventionally expressed by comparing its luff perpendicular, or LP, with the foretriangle base measurement J. A 150 per cent genoa has an LP equal to 1.5 times J; this does not mean that exactly half of the sail’s area overlaps the…
To tack a sailing vessel by turning its bow through the wind. As the bow crosses the wind, the sails cease drawing and then fill on the opposite side, placing the vessel on the other tack. The command may initiate a coordinated sequence of helm movement and releasing and trimming sheets, but exact calls and…
The articulated fitting connecting a boom’s forward end to a mast. Its joints allow the boom to swing from side to side and to change vertical angle while transmitting compression, bending and torsional loads between boom and mast. Some goosenecks are fixed at boom height, while a sliding type can move on a mast track…
A line used to control or brace the position of a spar, pole or other movable item. In conventional spinnaker handling, the afterguy controls the outboard end of the spinnaker pole and works with a foreguy or downhaul and the sheet. Terminology varies between rigs and regions, and on some systems the two working lines…
A sailing manoeuvre in which the stern passes through the wind and the sails change from one side to the other. A gybe occurs with the true wind abaft the beam and may be deliberate or accidental. As the wind changes sides, a boom or other sail-handling equipment can cross the vessel rapidly and the…
A warning call that a sailing vessel is beginning a gybe and the boom is about to cross the boat. The call alerts the crew to keep clear of the boom, mainsheet and associated tackle and to carry out their assigned actions. It is normally made as the helm is applied after the crew has…
A descriptive sailing expression for a sail or line running outward rapidly after it is released or loses restraint. A sheet can fly out through a block or fairlead and a sail can blow out to leeward when its control is released. The phrase is not a single standard technical manoeuvre and its intended meaning…
The lower edge of a sail between its tack and clew. A mainsail foot may be secured along a boom, retained only at tack and clew as a loose-footed sail, or arranged in another rig-specific way. The foot of a headsail usually spans above the deck rather than being attached to it. Outhaul and tack…
To let out a loaded line or control gradually while maintaining control of it. A sheet is eased to allow a sail to move farther from the centreline or to reduce load, while a mooring line may be eased to change the vessel’s position or share load with another line. The amount and rate depend…
A reinforced eye or loop in a sail or canvas item through which a fitting or line can take load. A cringle may be formed around a metal ring, sewn ring, rope eye or pressed eyelet and reinforced with patches, webbing or roping. High-load cringles are fitted at the head, tack and clew and at…
