Jury - The group of Rules experts who decide the outcome of protests.

Keelboat - e.g. Star, Elliott 6m- A boat with a "keel" - the fin attached to the bottom that prevents it from capsizing and stops it moving sideways through the water.

Kite (asymmetric) - A large, often colourful sail used during downwind sailing set in front of the other sails (carried by the 470, 49er and Elliott 6m) The 49er uses an asymmetric spinnaker. Also called spinnaker.

Knot - A measure of wind speed 1 knot = 1 nautical mile per hour, 1.15 mph and 1.85 km/h.
