PostHeaderIcon Battle Flag

a large flag or banner showing a particular boat’s colors or insignia, or that of her corporate sponsor. Usually flown from high up on the headstay.

PostHeaderIcon Anti-seize

thread lubricant that prevents binding, galling, and corrosion on turnbuckles, screw shackles, and other threaded devices. Used on anything with threads that you intend to take apart again.

PostHeaderIcon Hawaiian Rounding

a windward mark rounding where the inside boat (i.e., the one with rights) forces the outside boat a considerable distance farther outside—as in all the way to Hawaii. See also: proper course.

PostHeaderIcon Foreguy

a line used to control a spar in a horizontal or inclined position. A part of the running rigging. Some people use the term to refer to the line that controls a spinnaker pole’s outboard end. Compare to: downhaul.

PostHeaderIcon Eye candy

an attractive crew member who is onboard just for his or her looks. Also referred to as boat fluff, bow candy, deck fluff, deck jewelry, dock pop, or fashion statement.

PostHeaderIcon Donuts

slang for shackle guards, which are large-diameter plastic line guards that are placed around an eye-spliced spinnaker guy at a snap shackle. These prevent the shackle from jamming in the spinnaker pole’s jaw. Smaller diameter plastic balls are also used on halyards to prevent shackles from jamming in their sheaves.

PostHeaderIcon Bare Poles

without having any sails up and without an engine providing driving force while underway. In heavy weather, the windage of the mast and other spars can still be enough to move a boat. When a boat has no sails set and no motor running, she is said to be “under bare poles.”

PostHeaderIcon Afterguy

a control line used to adjust a spinnaker’s angle of attack to the wind and, therefore, its effectiveness, by rotating the spinnaker pole’s outboard end fore or aft as needed. An afterguy is adjusted in unison with the downhaul, spinnaker sheet and topping lift to form the spinnaker into the most efficient shape and to position the spinnaker at the most effective angle to the wind. The afterguy, often referred to simply as the guy, is run from a symmetrical spinnaker’s windward clew or an asymmetrical spinnaker’s tack when flown from a spinnaker pole, through the spinnaker pole’s jaw, then aft, optionally through one or more blocks, to a cockpit winch. Also referred to as a spin guy, spinnaker guy, or working guy. An afterguy is part of the running rigging. British and Commonwealth sailors use the term brace. See also: spin gear.

PostHeaderIcon Zincs

a less noble (i.e., less corrosion resistant) metal used to protect structural metals, such as through-hull fittings, propellers, and shafts, from the electrochemical degradation of galvanic corrosion. When two different types of metal are in contact and subject to a corrosive environment, such as immersion in saltwater, galvanic corrosion occurs and the least noble metal is sacrificed. For example, zinc is less noble than the brass used in propellers or through-hulls, so the zinc corrodes while the brass remains intact. The zinc is technically a sacrificial anode. If the zinc completely corrodes, the brass begins to corrode. Though commonly known as zincs, magnesium is often used as the sacrificial anode in freshwater, while zinc is used in saltwater. It is recommended that zincs be replaced when they have corroded to 50% of their original size.

PostHeaderIcon Duck

to pass behind an opponent who is crossing on the opposite tack. You perform a typical duck by recognizing the need early, footing off to accelerate for only as long as necessary to clear, then hardening up and sailing close-hauled as you cross your opponent’s stern. Also known as dipping or taking a stern. Compare to: cross.
