A ship hoists her National flag (Sometimes “Civil Ensign”) at ship’s stern to denote nationality and hoists a national flag of a country where ship called as a matter of courtesy at ship’s foremasthead. Few countries, such as the United Kingdom, have national flags for land purpose and ensign for maritime purpose with different pattern and they hoist ensign as ship’s own national flag at ship’s stern. When ordering please do not confuse this matter. Flags are made of warp-knitting polyester, if not any other material are specially required. The flag hook is normally separate order.
