It was in January 1807 that the Customs Board took into consideration the appointment of several Revenue cruisers and the expediency of one general system for manning them according to the tonnage and construction of the vessel, the service and station on which she was to be employed. They therefore distinctly classed the different cruisers according to their tonnage, description, and number of men originally allowed and since added, whether furnished with letters of marque or not. And believing that it would be beneficial to the service that the complement of men should be fixed at the highest number then allotted to cutters in each respective class, they accordingly instructed the commanders of the different cruisers to increase their respective complements "with all practicable dispatch."
We now come to an important point concerning which there exists some little uncertainty. By a letter dated July 17, 1807, Revenue officers were reminded that they were by law bound to hoist the Revenue colours and fire a gun as a signal "before they in any case fire on any smuggling vessel or boat."
"We direct you to convene the officers of the Waterguard belonging to your port," write the Commissioners to the Collector and Controller at each station, "including the officers and crew of the cruiser stationed there, and strictly to enjoin them whether on board cruisers or boats in no instance to fire on any smuggling vessel or boat, either by night (whether it be dark or light), or by day, without first hoisting the colours and firing a gun as a signal, as directed by law, and to take care that on any boat being sent out armed either from the shore or from a cruiser, in pursuit of seizures or any other purpose, such boat be furnished with a proper flag." Two years later, on April 11, 1809, it was decided that cruisers could legally wear a pendant "conformable to the King's Proclamation of the 1st January 1801," when requiring a vessel that was liable to seizure or examination to heave-to, or when chasing such a vessel, but "at no other time." It is important to bear in mind that the flags of chase were special emblems, and quite different from the ceremonial flags borne on the Customs buildings, hulks, and vessels not used actually in the chasing of smugglers.
