1. Ah! Thx, I i will correct this.
As for 2 and 3, the aim of the project is to document ways of communicating, even if they have fallen out of favor, which is the case for the ICS for pleasure boaters. Most sailors nowadays do not know the meanings of the flags(but they know the phonetic alphabet). The navy still uses it tho. I aim to make some flags this year to carry onboard our boat, to practice with, but we already had the Q and O flag onboard(still widely in use).
@tty We fly the Q flag when checking into a country (we flew it this year, although not everyone does this), and the O flag is usually attached to a long pole to use when someone falls overboard.
