The oceans' ABC.

Navigate your conversations with the flags of the International Code of Signals (ICS), also known as nautical, maritime or sea flags. Yes, not everyone will understand it, and maybe that's a good thing. It's like a secret code just for people who know the oceans' ABC. It includes all the alphabet flags, as well as the numerals, substitutes, and code/answer pennants.
