Only one flag, burgee, o Excerpted from: USPS Flag Etiquette at: usps.org/f_stuff/etiquett.htmlhttp://www.usps.org/f_stuff/etiquett.htmlCourtesy FlagsWhen you visit foreign water, your boat should display a courtesy flag (the civil ensign of the country you are visiting) whenever your U.S. national ensign (the USPS ensign or the yacht ensign should not be displayed in foreign waters) is displayed. (The USPS ensign and U.S. yacht ensign should not be worn in foreign waters)If your vessel is mastless, it should wear this "courtesy flag" at the bow, in lieu of a squadron or club burgee, or on a starboard antenna strong enough to support it. It your vessel has one or more masts, display it single-hoisted at the outboard signal halyard of the main starboard spreader. Move any flag normally flown there to the inboard starboard halyard or, if your boat has only one halyard per side, to the port spreader halyard.The customs observed in various foreign waters differ from one another. Try to learn the correct procedure for the country you are entering. For example, is some countries it is customary to fly the courtesy flag only after the quarantine flag (the yellow 'Q' flag) and the vessel has been granted pratique by the appropriate authorities.Do not fly a foreign courtesy flag after you have returned to U.S. waters. It is not to be used as a badge of accomplishment for having cruised to another country.
