A Special Mark, as defined by the International Association of Lighthouse Authorities, is a sea mark used in maritime pilotage. It is recognisable by its yellow colour and X, (often referred to as a St. Andrews Cross) top-mark. It has a distinctive sequence of various flashes that does not match any other navigational mark flashes in its vicinity.

Famous quotes containing the words special and/or mark:
“It is surely a matter of common observation that a man who knows no one thing intimately has no views worth hearing on things in general. The farmer philosophizes in terms of crops, soils, markets, and implements, the mechanic generalizes his experiences of wood and iron, the seaman reaches similar conclusions by his own special road; and if the scholar keeps pace with these it must be by an equally virile productivity.”
—Charles Horton Cooley (1864–1929)
“He was the mark and glass, copy and book,
That fashioned others.”
—William Shakespeare (1564–1616)
