When a ship is docked, where is the national ensign flown?

When a ship is docked, the national ensign is flown from the fantail, which is the term for the rear or stern of the ship. This practice is part of naval tradition and protocol, signifying the ship's presence and the nation it represents while in port.

Flying the flag from the fantail when moored is important as it maintains visibility of the ensign to those on land and other vessels nearby. It symbolizes the ship's connection to the country and serves as a reminder of its official duties while it is in a stationary position, distinct from when it's at sea where the flag may be flown from the mast to ensure it is prominently displayed and recognized by other vessels.
