PostHeaderIcon Spinnaker Pole Car

a device that allows a spinnaker pole’s inboard end to be raised or lowered to match wind and sailing conditions. The car travels on a vertically oriented track attached to the mast’s forward face. Either a pin stop or purchase system is used to control the car’s height. Also referred to as a mast car or pole slide.

PostHeaderIcon IMOCA

an acronym for the “International 60-foot Monohull Open Class Association.” Established in 1991 and recognized by ISAF since 1998, it is the governing body for the Ocean Racing World Championships, which include the Vendée Globe, the Route du Rhum, and the Transat Jacques Vabre. IMOCA is an open class, so anything is permitted unless the rules specifically prohibit it. See also: Equipment Rules of Sailing for 2013-2016 C.2.3. For more information, browse to

PostHeaderIcon Twinger

a snatch block placed on a spinnaker sheet between the spinnaker’s clew and an aft sheet block. It is a flying block that is manually adjusted by means of a control line led through a turning block or D ring at the rail. Used in a manner similar to a jib lead car to adjust a spinnaker’s sheeting angle. On a small boat that controls a chute with just two sheets, a twinger is trimmed in all the way on the line that is acting as a guy, to maintain a better working angle. Also referred to as a down-puller. Compare to: outgrabber. A twinger may also be used inside the rail on headsail sheets to improve the shape of reachers, screechers or even genoas when running downwind. In this case the set-up is more commonly referred to as a barber hauler.

PostHeaderIcon Rudderpost

the vertically-oriented shaft on which a rudder is mounted. A tiller is attached directly to the rudderpost or a wheel is attached by means of cables or chains and pulleys. When a wheel is used, the rudderpost’s top is often accessible through a deck opening in the cockpit so an emergency tiller can be fitted in the case of wheel failure.

PostHeaderIcon SCAR Pins

retaining devices that are used to prevent turnbuckles from accidental loosening, but that can be quickly removed for rig tuning. SCAR pins consist of a cotter pin or post attached to and held in place by a Velcro strap that gets wrapped around the turnbuckle’s body. Works on both open body and slotted tubular turnbuckles. Also known by many other names, including high-speed pins, quick pins, smart pins, and wrap pins.

PostHeaderIcon Bikes

slang for a winch grinding pedestal, a device used to provide turning power to one or more deck-mounted winch drums. Either a single crew member or two crew members that work in tandem operate what look like bicycle pedals mounted atop the pedestal. Also known as pumps.

PostHeaderIcon Emergency Tiller

a temporary bar or arm fitted to the head of a boat’s rudder. The emergency tiller is used to directly operate the rudder when wheel steering fails.

PostHeaderIcon Bight

1) An open loop in a line. “The bight” is the potentially dangerous area within a bight of line that is under load. For example, anyone sitting inside the bight of a working spinnaker sheet run through a turning block would likely be severely injured by both the sheet and shrapnel if the block’s sheave separated from its frame. 2) a shallow ocean inlet or indentation along a shoreline, such as the sea area between two promontories. Compare to: headland.

PostHeaderIcon Utility Winch

large grinding pedestal-driven winch located immediately behind the mast in the pit. Used to hoist, jibe, and douse sails. Also known as a bitch winch.

PostHeaderIcon Carbon Fiber

bundles of carbon-based filaments woven into sheets or tubes. When this fabric is embedded within plastic resin (i.e., epoxy) and formed into strong, lightweight material for such things as spars, structural members or hulls, the material is known formally as carbon-fiber-reinforced plastic (CFRP), but is often commonly referred to as carbon fiber. Carbon bundles may also be sandwiched between polyester film, such as Mylar, and formed into sails. See also: string sail. Compare to GRP.
