The International Code of Signals or Flag Code uses a clear and easily understandable “language”, and is of fundamental importance for the safety of everyone who goes to the sea.<\/p>\n\n

Until the 16th century the signalling between ships was done by hoisting the sails in certain positions or firing guns. Therefore, we know that Vasco da Gama signalled as follows:\u00a0A fire signal was an order to continue, two was to turn, three to hoist the sail and four to shorten sail.<\/p>\n\n

On the other side, during the 16th and 17th centuries the English and Dutch raised a red flag to signal the beginning of a battle and a black to signal its end.<\/p>\n\n

Since the beginning of the 18th century several naval communication codes have been elaborated and widely disseminated in the World Navy, such as that of the English Admiral Richard Howe in 1777. Other codes were also published such as the Danish (Rhode), the American (Rodgers) and the French (Reynold).<\/p>\n\n

Uma revis\u00e3o em 1961 resultou no c\u00f3digo atual, o qual foi concebido em 1855 e publicado na Inglaterra em 1857. A IMO (Organiza\u00e7\u00e3o Mar\u00edtima Internacional) editou-o pela \u00faltima vez em 1988.<\/p>\n\n

The C.I.S. consists of 26 alphabetical flags, 10 numeric, three substitute and a code or recognition pennant.\u00a0All alphabetical flags, except the letter “R” have a different meaning. They can be combined with each other and read from top to bottom. In this way, flags are recognized even when they are partially covered.<\/p>\n\n
