Footnotes

  • The International Code of Signals was drafted in 1855 and first published in 1857. In consisted of a series of alphabetic and numeral flags, together with three substitutes. Apart from spelling individual words and numbers, combinations of flags could be used with a code book to refer to more complex information. Originally, up to five flags could be used to convey locations throughout the world, however after revision in 1969 a maximum of three code flags are now employed. Thorough knowledge of the meaning of the signal flags and codes was a requirement of Board of Trade examinations for Mariners.
