Whereas by ancient usage no merchant's ship ought to bear the Jack, which is for distinction appointed for his Majesty's ships; nevertheless his Majesty is informed that divers of his Majesty's subjects have of late presumed to wear his Majesty's Jack on board their ships employed in merchants' affairs, and thinking to evade the Punishment due for the same, bear Jacks in shape and mixture of colours so little different from those of his Majesty as not to be without difficulty distinguisht therefrom, which practice is found attended with manifold Inconveniences; for prevention whereof for the future his Majesty hath thought fit, with the advice of his Privy Council, by this his Royal Proclamation, strictly to charge and command all his subjects whatsoever, that from henceforth they do not presume to wear his Majesty's Jack (commonly called The Union Jack) in any of their ships or vessels, without particular warrant for their so doing from his Majesty, or the Lord High Admiral of England, or the Commissioners for executing the office of Lord High Admiral for the time being; and his Majesty doth hereby further command all his loving subjects, that without such warrant as aforesaid, they presume not to wear on board their ships or vessels, any Jacks made in imitation of his Majesty's, or any other flags, Jacks, or Ensigns whatsoever, than those usually heretofore worn on merchants' ships, viz., the Flag and Jack White, with a Red Cross (commonly called Saint George's Cross) passing right through the same; and the Ensign Red, with a like Cross in a Canton White, at the upper corner thereof next to the staff. And his Majesty doth hereby require the principal officers and Commissioners of his navy, Governors of his Forts and Castles, the Officers of his Customs, and Commanders or officers of any of his Majesty's ships, upon their meeting with, or otherwise observing any merchants' ships or vessels of his Majesty's subjects wearing such a flag, jack, or ensign, contrary hereunto, whether at Sea or in Port, not only to cause such flag, jack or ensign to be forthwith seized, but to return the names of the said ships and vessels, together with the names of their respective masters, unto the Lord High Admiral, Lords Commissioners of the Admiralty, or the Judge of the High Court of Admiralty for the time being, to the end the Persons offending may be duly punished for the same.
