Saltwater Suzi and Cap'n Larry's advice for the cash-starved boater
How to Sound Salty
Sail-plan - A set of drawings showing various sail combinations recommended for use in various situations.
Sampson post - A strong vertical post used to support a ship's windlass and the heel of a ship's bowsprit.
Scope - the length of the anchor line - from the boat to the anchor.
Scuppers - Openings in toerails or drains in decks used to channel water from waves or rain off of the deck.
Sea anchor - A stabilizer deployed in the water for heaving to in heavy weather. It acts as a brake and keeps the hull in line with the wind and perpendicular to waves.
Seacock- a valve in the hull of a boat.
Sextant - Navagational instrument used to measure a ship's latitude and longitude.
Shackle - Part of the indispensable equipment on the boat. It is a small device used for attaching lines to other things, like sails.
Sheer - The upward curve of a vessel's longitudinal lines as viewed from the side.
Sheet- A line used to trim sails.
Ship's bell - Striking the ship's bell is the traditional method of marking time and regulating the crew's watches. Also used as a warning of a vessel’s presence in fog.
Shoal- Shallow water that is a hazard to navigation.
Shoal draft - a vessel with shallow draft, capable of sailing in unusually shallow water.
Shoaling - A phenomenon occurring as the waves enter a shallow water - their movement forward is slowed down because of the bottom friction, and thus their height increases.
Shroud - The wires holding the mast at the sides.
Skeg - A downward or sternward projection from the keel in front of the rudder. Protects the rudder from damage, and in bilge keelers may provide one "leg" of a tripod on which the boat stands when the tide is out.
Skipper - The Captain of a ship.
Sounding- Measuring the depth of the water.
Spar - A general name for all masts, booms, gaffs, and bowsprits.
Spinnaker- A large sail flown in front of the vessel while heading downwind.
Spinnaker pole- A spar used to help control a spinnaker or other headsail.
Splice - To join lines (ropes, cables etc.) by unravelling their ends and intertwining them to form a continuous line. To form an eye or a knot by splicing.
Splice the Mainbrace- Have a drink (see History of this phrase here) Spreaders- The wooden or metal struts that are attached horizontally to the upper section of the mast, on both sides. They widen the angle of the shrouds, and thus provide a better support for the mast.
Stanchion - vertical post near a deck's edge that supports life-lines. A timber fitted in between the frame heads on a wooden hull or a bracket on a steel vessel, approx one meter high, to support the bulwark plank or plating and the rail.
Standing rigging - Rigging which is used to support masts and spars, and is not normally manipulated during normal operations. Cf. running rigging.
Stand-on vessel - A boat that has the right-of-way over the give-way vessel. It must maintain its course and speed unless a collision is imminent.
Starboard - Towards the right-hand side of a vessel facing forward. Denoted with a green light at night.
Starboard Side - The boat's right side.
Starboard tack - When sailing with the wind coming from the starboard side of the vessel. Has right of way over boats on port tack. A vessel on a starboard tack has its sails on the port side.
Stays - Wires supporting the mast - fore and aft .
Staysail - A sail whose luff is attached to a forestay.
Stem - The extension of keel at the forward end of a ship.
Stern - The back of the boat.
Stopper knot - A knot tied in the end of a rope, usually to stop it passing through a hole; most commonly a figure-of-eight knot.
Surf - A continuous line of breakers at the shore.
Swinging the compass - Measuring the accuracy in a ship's magnetic compass so its readings can be adjusted - often by turning the ship and taking bearings on reference points.
Tabernacle - A large bracket attached firmly to the deck, to which the foot of the mast is fixed. It has two sides or cheeks and a bolt forming the pivot around which the mast is raised and lowered.
Tack- (verb) to come about (see coming about.) (noun) the fore corner of a triangular sail.
Tack hook - A snap used to hold the tack of the jib at the bow, while the sail is raised.
Tack pin - A pin used to secure the tack of a triangular sail at the mast.
Tacking - see coming about
Taffrail - A rail at the stern of the boat that covers the head of the counter timbers.
Telltales- Short pieces of yarn attached to the shrouds, or the sails. At the shrouds they indicate the direction of the apparent wind, and on the sails they help to check the air flow over the sail, so that proper trimming is easier.
The Ensign - A flag indicating nationality of the vessel.
Tiller- A spar attached to the rudder by the rudder head, used to control the direction of the boat. Another possibility for steering mechanism is a steering wheel.
Toe-rail - A low strip running around the edge of the deck like a low bulwark. It may be shortened or have gaps (scuppers) in it to allow water to flow off the deck.
Topsides - the part of the hull between the waterline and the deck.
Traffic Separation Scheme - Shipping corridors marked by buoys which separate incoming from outgoing vessels.
Trampoline - The space on a catamaran, usually made of some kind of mesh, located between the two hulls . It's a place for the crew (like a cockpit on dinghies and cruisers).
Transom - a more or less flat surface across the stern of a vessel. Dinghies tend to have almost vertical transoms, whereas yachts’ transoms may be raked forward or aft.
Traveler- A track (usually metal) with a fixture sliding on it. The fixture holds the main sheet (usually), and the sliding allows for changing angles of the sail.
True bearing - An absolute bearing using true north.
True north - The direction of the geographical North Pole.
True wind - The strength and direction of the actual wind blowing. While sailing, the true wind is never felt - it is always a combination of the true wind, and the boat's speed (called the apparent wind ), and it is always a little forward of the true wind.
Trysail - A very small sail, used in a very heavy weather instead of a mainsail. Tumblehome - A description of hull shape when viewed from directly in front or from directly behind, where the widest part of the hull is someway below deck level.
Turn- A knot passing behind or around an object.
Under way - A vessel that is moving under control.
Vang - see boom vang
Watch - A period of time during which a part of the crew is on duty. Changes of watch are marked by strokes on the ship's bell.
Waypoint - A location defined by navigational coordinates, especially as part of a planned route.
Weigh anchor - To heave up (an anchor) preparatory to sailing.
White horses or whitecaps - Foam or spray on wave tops caused by stronger winds (usually above Force 4).
Winch - A mechanical device used to assist in pulling on lines. It is a reel-like part of the hardware.
Windage - Wind resistance of the boat.
Windlass - A winch mechanism, most commonly used in raising the anchor.
Windward - The direction from which the wind is blowing.
Yaw - A vessel's rotational motion about the vertical axis, causing the fore and aft ends to swing from side to side repetitively.
Yawl - A two-masted sailboat, the aft mast (the mizzenmast) is shorter than the forward (the main mast.) The mizzenmast is located behind the rudder post - otherwise it is a ketch.
