There are many customs and traditions associated with the Royal Navy of the United Kingdom. Many of these traditions have carried on to other Commonwealth navies, such as Canada, India, Australia and New Zealand. These include formal customs such as separate crests associated with ships, ensigns and fleet reviews. There are also several less formal customs and traditions, including Naval slang commonly referred to as Jack Speak and the traditional games of Uckers and Euchre. Heraldry Ensigns Commissioned ships and submarines wear the White Ensign at the stern whilst alongside during daylight hours and at the main-mast whilst under way. When alongside, the Union Jack is flown from the jackstaff at the bow, but can only be flown under way on special circumstances, i.e. when dressed with masthead flags (when it is flown at the jackstaff), to signal a court-martial is in progress (when it is flown from the starboard yardarm), or to indicate the presence of an Admiral of the Fleet, including the Lord High Admiral or the Monarch (when it is flown from the highest hoist). Ships badges The Royal Navy assigns badges to every ship, submarine, squadron and shore establishment. Prior to the age of steam ships, ships were identified by their figurehead. With the removal of the figurehead, ships badges and mottos were created to graphically represent the ships. The official process for creating the badge was initiated by Charles ffoulkes after World War I who was appointed as the Admiralty Advisor on Heraldry. Soon after his appointment The Ships' Badges Committee was established. This was amalgamated in 1983 with the Ships' Names Committee (founded in 1913) to create the Ships' Names and Badges Committee. The Naval Crown adorns the top of all the badges. The frame is gold rope. Originally, different classes of ships had different shapes, but currently all ships and submarines have a circular design. Shore establishments have an offset square design. Ceremonial The Royal Navy uses a number of unique ceremonies which often have their origins in the days of sail. Colours This is the formal ceremony of raising or lowering of a ship's ensign and jack when in port or at anchor. All shore establishments only fly the White Ensign. The lowering ceremony is referred to as "Sunset" or "Evening Colours" if sunset occurs after 2100. It may be accompanied by the "Sunset" bugle call. Ships at sea fly the White
