Sailboat Flag Etiquette: Your Questions Answered

Some British sailboats fly a white or blue ensign because they belong to certain yacht clubs or organisations that have special permission to use these ensigns.

The white ensign is a variation of the national flag that is normally used by the Royal Navy, but it can also be worn by yachts owned by members of the Royal Yacht Squadron, which is a privileged yacht club with a long history and close ties to the monarchy.

The blue ensign is another variation of the national flag that is normally used by government vessels, but it can also be worn by yachts that belong to one of the 32 yacht clubs or associations that have a warrant from the Admiralty or the relevant authority to use the undefaced blue ensign.

Additionally, some yachts can wear a blue ensign defaced with the badge of their club or association, if they have a warrant for that as well. There are 57 yacht clubs or associations that have this privilege.

These special or privileged ensigns are considered a mark of distinction and honour, and they should only be flown with proper authorisation and following the rules and regulations of wearing them.

An ensign is a flag that shows the nationality of the vessel and must be worn at the stern or as close to it as possible. A burgee is a flag that shows the membership of a yacht club or sailing association and can be worn at the masthead or the port spreader.

A special ensign is a variation of the national flag that can be worn by certain yachts that belong to a privileged yacht club or organisation. To get one, you need to apply for a warrant from the Admiralty or the relevant authority and follow the rules and regulations of wearing it.

The size of your flags depends on the length of your vessel, but as a general rule, your ensign should be about one inch for each foot of overall length. Your burgee and courtesy flag should be smaller than your ensign, but not too small to be seen. You should hoist your flags using halyards or staffs and make sure they are not tangled, faded, or torn.

You should raise your flags at 0800 hours or when you leave harbour, whichever is later, and lower them at sunset or when you enter harbour, whichever is earlier. You should also lower your flags when out of sight of other vessels or when nobody is aboard.

Traditionally, you should only fly one burgee at a time, but some yachts may choose to fly more than one to show their affiliation with different clubs or associations. However, you should always make sure that your burgee matches your ensign if you are wearing a special one. You can also fly other flags, such as signal flags, house flags, or personal flags, but they should not take precedence over your ensign, burgee, or courtesy flag.

You can salute other vessels or authorities by dipping your ensign, which means lowering it halfway down the staff or halyard and then hoisting it back up. You should only do this if you receive a salute first or if you are passing by a naval vessel, a Coast Guard vessel, or a foreign warship.

The rules for flying flags in a race may vary depending on the organising authority, but generally, you should not fly your ensign during a race, as this signals that you are not racing. You should also follow any instructions given by the race committee regarding signal flags, class flags, or protest flags.

Not following flag etiquette may result in fines, penalties, or even confiscation of your vessel if you break the law or offend the host country. It may also cause confusion, misunderstanding, or disrespect among other sailors or authorities. Therefore, it is advisable to learn and follow the proper flag etiquette whenever you go sailing.

In maritime flag etiquette, a vessel is said to be “dressed overall” when it is displaying its full complement of flags—often including its national ensign, club burgee, courtesy flag, and any additional signal or decorative flags—in the orderly, prescribed arrangement. Rather than simply flying the mandatory flag (for example, the ensign), a boat “dressed overall” presents all its “colours” from stem to stern. This is especially common during special occasions—such as national festivities, club events, or in-port celebrations—where the boat is ceremonially arrayed to project respect, pride, and an elevated sense of maritime tradition.
