Which flag should one fly when entering the territorial waters of another country?
Anyone entering the territorial waters of another country should display the national flag of the country whose territorial waters they are entering. In addition, it may also be necessary to fly the host country flag. When doing so, it is important to research the host country's flag regulations and abide by them to avoid misunderstandings or fines.

Taking down the flags: Here's what you should look out for
The national flag must be clearly visible at all times, as required by law. This is attached to an inclined pole at the stern or flown at sea in the leech of the mainsail or in the top of the aft mast. The flag parade is an international seaman's custom and is not codified in law.
Nowadays, flags are hoisted at 8 am from 1 May to 3 September and at 9 am in the remaining months. In the evening at sunset, no later than 9 pm, flags are taken down. Hoisting is often considered an act of courtesy abroad and should therefore be respected.
How do you find out which flag to fly?
- Research in advance which flags must be displayed in the territorial waters of the country concerned (e.g. official website of the country's government)
- Guide for sailors (online or in book form)
- Sea maps
- Local port authorities
