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.
A heavy rope, wire rope or chain used for anchoring, mooring, towing or other load-bearing service. In traditional and regulatory language, an anchor cable may be chain, rope or a combination of both. The word also has electrical and communications meanings aboard a vessel, so context is important. Cable strength, elasticity, weight, corrosion, chafe, bend…
A downwind sail arrangement with the mainsail and headsail set on opposite sides of the vessel. The mainsail is eased to one side while the headsail is held out on the other, often with a whisker pole. This exposes both sails to the following wind and reduces the tendency of the mainsail to blanket the…
The senior deck crew member responsible for supervising deck work, maintenance and seamanship equipment. The bosun normally allocates and oversees work involving mooring, anchoring, cargo or deck operations, rigging, small boats, painting and preservation. The exact duties and authority vary with vessel type, manning and organisation. Bosun is the usual spoken and informal spelling of…
The complete connection between a vessel and its anchor, made from chain, rope or both. An anchor rode may be all chain, all rope, or rope joined to a chain leader. Its size, material, length, elasticity and connections must suit the vessel, anchoring depth, seabed, wind, waves and current. Adequate scope helps the anchor pull…
Reducing a sail’s exposed area to control power and loads as wind or sea conditions increase. A slab-reefed mainsail is lowered sufficiently to secure a new tack and clew at reef points, then retensioned. Roller reefing reduces area by winding sail around a foil, mast or boom, while traditional sails may use other systems. Reefing…
A hook used to secure a mainsail’s reef tack or cringle near the gooseneck. Often called a ram’s horn, it holds the selected reef cringle at the forward end of the boom while the reef clew is tensioned aft. Some systems use a tack line or single-line reefing instead of a hook. The cringle must…
To arrange a line or sail in orderly folds so it can be stored or run without tangling. A line may be flaked in long back-and-forth turns on deck or into a container, especially before it must pay out rapidly. A sail may be flaked in alternate folds along a boom or on deck for…
Laying a line in long, orderly turns so it remains clear and can run out without tangling. The turns are normally placed back and forth on a clean deck or in a suitable container, with the end required first positioned for a clear lead. This is particularly useful for heaving lines, towlines, halyards and other…
Folding a sail in neat alternating layers for securing, handling or storage. A mainsail is commonly flaked along the boom with folds laid to alternate sides before sail ties or a cover are fitted. A removed sail may be spread, dried and folded according to its cut, battens and storage requirements. Orderly flaking reduces bulk…
To trim or hold a sail so the wind presses on the side opposite its normal driving side. A backed headsail can push the bow away from the wind during a tack, help balance a vessel when hove to, or drive the vessel astern in a controlled manoeuvre. A sail may back unintentionally when the…
