Configuration of typical brig-sloop.  In the 1770s, the two-masted sloop re-appeared in a new guise as the brig sloop. The successor to the former snow sloops, brig sloops had two masts while ship sloops continued to have three (since a brig is a two-masted, square-rigged vessel and a ship is a square-rigger with three or more masts, though invariably only three in that period).
