A ship with Polish nationality is marked with its name on each side the bow and on the stern. The registration number and the name of the ship's Port of Registry should be displayed under the name on the stern.

The name may consist of characters used in Polish (all English characters are included in the Polish alphabet) and Arabic or Roman numerals; the name length cannot be longer than 33 characters. 

The yacht's name cannot be identical in spelling or pronunciation to the spelling or pronunciation of words used to denote emergency services and their activities. The name cannot contain words or phrases commonly considered vulgar or offensive

All Polish registered boats must have a Port of Registry; this home port should be a sea port in Poland. Names of sea ports in Poland are:

• Darlowo
• Elblag
• Gdansk
• Gdynia
• Hel
• Kolobrzeg
• Police
• Sopot
• Swinoujscie
• Szczecin
• Ustka
• Wladyslawowo

This number is unique to each craft and identifies the manufacturer, where it is established and when the craft was built. The WIN Number should be permanently installed on or near the transom, starboard side, near the top of your yacht. A copy of the WIN is attached in a hidden place inside the cabin as a security check:
