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.Towards or in the front part of a vessel, in the direction of the bow. Forward may describe direction, as in “move forward”, or position, as in “the forward cabin”. Its opposite aboard is aft, and its meaning remains tied to the vessel even when a person is facing another way. The word does not…
The vertical distance between a vessel’s waterline and a defined deck or upper reference point. In formal ship measurement, freeboard is measured to the assigned freeboard deck or deck line under the applicable load-line rules. In everyday small-craft use, the word often describes the height from the water to the deck edge or another stated…
The greatest permitted steering angle of a vessel’s rudder to one side. Applying full rudder turns the rudder to the limit allowed by the steering system. It is used when a strong turning effect is required, although the response still depends on water flow over the rudder, vessel speed, hull form and environmental conditions. More…
To gather, roll or fold a sail into its stowed or reduced state. A sail may be rolled around a stay or spar, drawn into a mast or boom, or lowered and secured with sail ties. Completely furling removes it from use; partially rolling a sail reduces area only when the sail and furling system…
The action or equipment used to gather, roll or fold a sail into a stowed or reduced state. Headsail systems commonly rotate a foil or stay, while in-mast and in-boom systems roll a mainsail inside or along a spar. Traditional furling instead lowers and secures the sail without a rotating mechanism. A furling system eases…
A fore-and-aft rig in which a gaff supports the head of a generally four-sided sail. The gaff’s forward end lies against or near the mast and its aft end extends to the sail’s peak. Throat and peak halyards commonly hoist and control it, while the sail’s foot may be set on a boom or left…
The compartment or designated area aboard a vessel where food is prepared and cooked. A galley may range from a small counter with a single cooker and sink to a staffed commercial kitchen. Storage restraints, fiddles, latches and sometimes gimballed appliances help equipment and cookware remain controlled as the vessel moves. Fuel isolation, ventilation, flame-failure…
A pigmented surface resin applied to the mould before a fibre-reinforced composite hull or component is laminated. Gelcoat is commonly based on unsaturated polyester or vinyl ester resin. It provides a smooth coloured finish and a protective surface barrier, but it is not the structural laminate and should not be assumed to remain completely impermeable…
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…
A fibre-reinforced composite in which glass reinforcement is embedded in a cured polymer resin. The reinforcement may be chopped strand mat, woven cloth, stitched fabric or unidirectional fibres, while the matrix is commonly polyester, vinyl ester or epoxy resin. Strength and stiffness depend on fibre type, orientation and quantity, laminate design, resin choice and the…
