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.

A nine-digit identity transmitted by maritime radio systems to identify a ship, coast station, group or other assigned station type.

A principal upright or near-upright spar or structure that supports sails, rigging or equipment aboard a vessel. A sailing mast carries sail and rig loads through standing and running rigging and may be deck-stepped or keel-stepped. Power vessels also use masts for lights, antennas, radar, signals and sensors, and construction may be timber, aluminium, steel…
The structural fitting or support on which the heel of a mast is seated. A mast step locates the base of the mast and transfers compression and other rig loads into the vessel’s structure. It may be on deck, on the coachroof or lower in the hull for a keel-stepped mast, and its form must…
A white navigation light showing over the forward sector of a vessel. Despite its name, a masthead light need not be positioned at the physical top of a mast.

Their size, material and attachment depend on…
To secure an item with lashings so that it cannot shift beyond acceptable limits. Lashings may use rope, webbing, chain, wire or purpose-made restraints attached between suitable strong points. The arrangement must resist loads in all relevant directions, including acceleration from pitching, rolling, slamming and collision avoidance, rather than merely hold the item down vertically….
A storage or service compartment in the after part of a vessel. A lazarette is commonly beneath the cockpit or aft deck and may contain steering gear, batteries, pumps, fuel-system components, shore-power equipment or general stores.
