Syrik's Drunken Sailing
On the sea, the position of your flag can mean the difference between life and death. Even pirates prefer to obey flag etiquette unless they’re deliberately attempting to deceive others. Three types of flags are commonly used on the water.
Ensign: An ensign is a ship’s domestic flag. For example, an Roman ship would fly the Roman flag as its ensign.
Courtesy: A courtesy flag is the flag of a foreign nation. A Roman ship in Tholl waters would fly the Tholl flag as its courtesy flag.
Private Signal: A private signal is the personal flag of a particular ship or captain. This flag is usually the captain’s personal emblem or the emblem of an organization. A Roman privateer must register her personal emblem before obtaining her letters of marque; this emblem appears on her private signal, and helps the government track her ship.
Ships use several common flag positions to signal their intentions. In domestic waters, a ship flies its ensign at the top of the mast. Beneath the ensign appears the ship’s private signal. A private signal flown alone means the ship considers itself unaffiliated with any government—in short, a pirate vessel. Pirate flags are generally flown alone.
In foreign waters, a ship flies the courtesy flag at top mast. Beneath the courtesy flag, ships fly the ensign and then the private signal. Flying an ensign without a courtesy flag in foreign waters can be seen as a declaration of hostile intent. On ships without a flagpole, the ensign is always hoisted aft, as close to the stern as possible. The courtesy flag, if any, is flown fore (close to the bow) and the private signal is flown amidships. A flag flown upside-down is a signal of distress.
