Vessels at sea do not use the national flag as an ensign. Merchant vessels and pleasure craft fly a civil ensign of red charged in white with a variant of the crescent and stars emblem in the centre. Non-military government vessels such as coast guard ships fly a state ensign of blue with the national flag in the canton, charged with an eight-pointed red and white compass rose in the lower fly. Naval warships fly a naval ensign similar to the state ensign, but in white with a red compass rose emblem.
