CANTING KEEL A traditional keel is xed and points straight down beneath the centreline of a yacht. A canting keel is able to pivot either side of the centreline to better counteract the heeling force of the sail and improve performance, particularly upwind.
COASTAL RACE OR INSHORE RACE A race that uses a combination of natural features, naviga- tion marks and laid buoys within sight of land to create a course that usually lasts between two and four hours in time; the actual distance sailed will depend upon the strength of the wind, and size of yachts competing.
COMMODORE The senior of cer elected by the membership to lead and represent a yacht club; supported by other elected of cers, for example vice commodores and rear commodores, which may have speci c areas of responsibility.
CORRECTED TIME The recalculation of a yacht’s elapsed time according to its individual rating or handicap (which is typically based on parameters such as its hull dimensions, displacement and sail area).
CORINTHIAN Refers to a non-professional sportsman or sportswoman whose spirit and approach to competition is of the highest standard.
DISPLACEMENT Measured in tonnes, calculates the weight of the water displaced by a yacht when oating.
DOUBLE-HANDED Yacht sailed by a two-person crew.

LATITUDE Lines mapped around the Earth’s surface parallel to the equator, used to de ne the north/south position of a yacht.
LINE HONOURS Awarded to the rst nisher of an offshore race; a position often contested by the fastest state-of-the-art designs; the winner receives a Rolex timepiece.
LONGITUDE Lines mapped around the Earth’s surface perpendicular to the equator, used to de ne the east/west position of a yacht.
MAXI A high-performance yacht measuring between 24.09–30.5 metres (80–100 feet).
MAXI 72 A 21.94-metre (72-foot) all-out racing boat, equally adept at competing in inshore or offshore races.
MONOHULL A yacht with a single hull. Boats with two or three hulls are referred to as multihulls.
NAUTICAL MILE A measure of distance at sea. 1 nautical mile = 1.852 kilometres.
NAVIGATOR A key position onboard, the navi- gator is responsible for de ning the optimum route between any given points – usually marks of the race course – based on geographical and meteorological factors (member of afterguard).
OFFSHORE RACE A long-distance race, usually between two different places / ports, which takes the eet through open water, out of sight of land. Also referred to as ocean race or bluewater race. Rolex-sponsored offshore races in-clude the Rolex Sydney Hobart Yacht Race and the Rolex Fastnet Race.
