Where is the ensign typically displayed when a ship is in port?

The ensign is typically displayed at the flagstaff when a ship is in port. This is in accordance with maritime tradition and signals the nationality of the vessel. The flagstaff, located at the highest point on the ship, is an appropriate position for the ensign as it allows for visibility and proper representation of the ship's registration. Displaying the ensign at the flagstaff reinforces the ship's identity and establishes its presence in a designated port.

Placing the ensign at the bow or stern could lead to ambiguity in representation or visibility, while using the gaff is more suited for other flags or pennants, such as those that indicate specific information about operations or activities of the ship rather than its national designation. Thus, the flagstaff serves as the standard and most recognized location for displaying the ensign in port.
