About Nautical Flags Numerals


The system of international maritime signal flags (nautical flags) is one system of flag signals representing individual letters of the alphabet in signals to or from ships. It is a component of the International Code of Signals (ICS).1

There are various methods by which the nautical flags can be used as signals:

  • each nautical flag spells an alphabetic message, letter by letter.
  • individual nautical flags have specific and standard meanings;[2] for example, diving support vessels raise the “A, ALFA” flag indicating their inability to move from their current location because they have a diver underwater and (more importantly) to warn other vessels to keep clear to avoid chopping up the diver(s) with their propellers.
  • one or more nautical flags form a code word whose meaning can be looked up in a code book held by both parties. An example is the Popham numeric code used at the Battle of Trafalgar.
  • in yacht racing and dinghy racing, flags have other meanings; for example, the “P, PAPA” flag is used as the “preparatory” flag to indicate an imminent start, and the “S, SIERRA” flag means “shortened course” (for more details see Race Signals).1
