Nautical Flags Honor

Vocational Activities

Requirements

1. Why does the International Code of Nautical Flags exist, what is it for, and where is it used?

   Answer: 1) Why it exists: it was created to allow communication between vessels of different nationalities and languages, in a standardized and language-independent way, and as an alternative when the radio fails or when radio silence is required. 2) What it is for: it is a standardized visual communication system between vessels of any nationality, transmitting messages through flags with alphabetic, numeric, and signal meanings. 3) Where it is used: in ports, marinas, and ships on the high seas (between vessels or between ship and shore). — The ICS was created in 1855 by the British Board of Trade and revised by the ITU in 1969, standardizing 40 flags for letters, numbers, and international messages recognized by sailors of every country in the world.

2. Know the meaning of pennant.

   Answer: A pennant is a nautical flag of triangular or elongated rectangular shape, used to represent numbers (0-9) or repetition messages in naval codes. It differs from the square letter flags. — Pennants have a medieval origin on Viking ships (9th century), were formalized in the British Royal Navy in 1857, and were adopted by the ICS to distinguish numeric communication from alphabetic communication in navigation.

3. Using drawings or photographs, make a chart displaying the nautical flags, with their respective alphabetic and numeric meanings, as well as the message that the flag conveys when used on its own.

   Answer: You draw each of the 26 letter flags (A-Z) with the correct colors (blue, red, white, yellow, black), include numeric pennants (0-9), the isolated message of each one, and three special flags. — The ICS has 40 flags in total: 26 alphabetic + 10 numeric + 4 substitutes, standardized by the International Maritime Organization since 1969 and used globally by every navy in the world today.

4. Define 10 examples of nautical flag combinations.

   Answer: 10 exemplos de combinações (içamentos) de bandeiras náuticas do Código Internacional de Sinais: 1) NC - Estou em perigo e necessito de assistência imediata. 2) AN - Necessito de um médico. 3) AE - Tenho de abandonar meu navio. 4) CB - Necessito de assistência imediata. 5) DV - Estou à deriva. 6) JL - Você está correndo perigo de encalhar. 7) PD - Suas luzes de navegação estão apagadas. 8) UM - O porto está fechado à navegação. 9) QQ - Necessito inspeção sanitária (saúde/quarentena). 10) RY - Navegue com velocidade reduzida ao passar por mim. (Bandeira isolada também tem significado: ex. A 'tenho mergulhador na água', O 'homem ao mar', Q 'meu navio está livre, solicito livre prática'.) — Flag combinations follow the standardized code of the International Maritime Organization since 1969, with more than 1,500 combinations officially cataloged for specific situations in modern international navigation.

5. Identify the 4 substitute pennants and explain their use.

   Answer: You identify the 4 substitute pennants (1st, 2nd, 3rd, 4th substitute), triangular flags of distinctive color used to repeat a previous flag in messages with repeated letters/numbers, avoiding having to carry two identical ones. — Substitutes were standardized by the ICS in 1932 and revised in 1969 by the IMO, preventing ships from needing to carry duplicate flags for messages such as 'BABA' that repeat characters in sequence.

6. With 2 groups, hold a dialogue using nautical flags, exploring their individual and combined meanings, with a minimum distance of 300 meters between the groups.

   Answer: You agree on the code with each group beforehand, use large (>1m), brightly colored and visible flags, short and clear messages, hoist them high on masts, wait for a reply before the next one, and use binoculars to check. — Standard nautical communication requires flags of 1.5-2m at distances above 200m, according to the Signals Manual of the Brazilian Navy based on the international ICS for adequate visibility on the high seas today.
