Local shipwrights built schooners, brigs and dories. Popular modern tall ship rigs include topsail schooners, brigantines, brigs and barques. They were rigged as schooners, brigs or brigantines. In 1854 alone, the city built eleven ships, three barks, six brigs and four schooners. Each commander had a number of frigates, sloops and brigs at their disposal. His command included 1 frigate, 7 corvettes, 3 brigs and 6 steamships. The fleet also included five 40-gun frigates and two 18-gun brigs, all French. Later British seagoing training ships were smaller purpose-built brigs. The corvettes and brigs carried 1134 guns. Larger yards built wooden sailing collier brigs, used to transport local coal to London. The glassware was then exported in collier brigs. The keels of two brigs were each constructed out of a single black oak log. Brigs vary in length between with tonnages up to 480. The initial sighting of the two Mexican brigs was at about 5&colon;30 am. The next day "Brev Drageren" unsuccessfully re-engaged first one and then two of the brigs.
