PostHeaderIcon Going Over the Handlebars

hitting something or stopping very suddenly, such as by burying the bow in a wave. See also: down-the-mine, pitchpoling and poop stance.

PostHeaderIcon Fast Forward

sailing low and fast on a beat. See also: acceleration mode and rumble.

PostHeaderIcon Truck

a short arm atop the masthead used as the backstay attachment point and as a mounting bracket for the main halyard sheave, allowing it to be located aft of the mast for a better fairlead to the mainsail’s headboard. Also known as a crane. See also: spinnaker bail and stern fitting.

PostHeaderIcon Cone of Protection

a theoretical safety zone protected against lightning strikes provided by a boat with her mast, engine, and other large metal objects electrically bonded together and well-grounded. It is a cone extending from the masthead to the water’s surface, out to a radius approximately equal to the mast’s height. Known in the world of physics as a Faraday’s Cage. For more information, see the American Boat and Yacht Council’s standards and technical report on lightning protection TE-4, available at

PostHeaderIcon Saildrive

an engine, transmission, and propeller drive system connected in a single package. The engine connects directly to the drive unit that contains the transmission, and extends down from the bottom of the hull. A saildrive eliminates a traditional inboard motor’s extended propeller shaft, cutlass bearing, and stuffing box.

PostHeaderIcon Trade Winds

strong, stable winds that blow toward the Equator from the northeast in the belt just north of the doldrums, and from the southeast in the belt just south of the doldrums.

PostHeaderIcon Racing Stripes

fenders unintentionally left in place after the boat has left the harbor.

PostHeaderIcon Kelp Windows

small windows placed in a hull’s bottom, just forward of the keel and to either side. Used to visually check whether kelp or other flotsam is fouling the keel. Usually not very informative as kelp tends to ride very high on a keel, while the view from these windows is farther down. A window placed directly over the keel’s leading edge offers a more informative view. Another version, referred to as an endoscope, is a miniature, freely rotating periscope that extends downwards through hull fittings located at various places along a boat’s bottom. This lets the crew view the boat’s entire bottom, keel, rudder, and propeller. See also: endoscope and kelp cutter.

PostHeaderIcon Code 0

a hybrid sail designed to work like a large, loose-luffed genoa for very tight, light to medium air reaching, but meeting certain measurement requirements so that it is rated as a spinnaker. A Code 0’s typical effective wind range is approximately 45 degrees apparent in 3-6 knots true wind speed and up to 100 degrees apparent in 9-11 knots true wind speed. It is an asymmetrical sail with the most upwind capability. The luff is as straight as possible, and the sail is flatter than other spinnakers. Due to the Code 0’s flatness, it is usually made with a wire luff for strength, and of a heavier, less stretchy fabric than normal for a spinnaker. With a tight luff and flat cut, the code 0 can be fitted for roller furling. Also called a gennaker. See also: daisy. Compare to: A1 and drifter.
