By the first half of the 18th century the word had evolved to refer not to a ship type name, but rather to a particular type of rigging: square-rigged on the foremast and fore-and-aft rigged on the mizzen. Many sloops were "brigantine-rigged".
The 1780 Universal Dictionary of the Marine by William Falconer defines brig and brigantine as follows:
- BRIG, or BRIGANTINE, a merchant-ship with two masts. This term is not universally confined to vessels of a particular construction, or which are masted and rigged in a method different from all others. It is variously applied, by the mariners of different European nations, to a peculiar sort of vessel of their own marine.

- Among English seamen, this vessel is distinguished by having her main-sail set nearly in the plane of her keel; whereas the main-sails of larger ships are hung athwart, or at right angles with the ship’s length, and fastened to a yard which hangs parallel to the deck: but in a brig, the foremost edge of the main-sail is fastened in different places to hoops which encircle the main-mast, and slide up and down it as the sail is hoisted or lowered: it is extended by a gaff above, and by a boom below.
- 1. a. A vessel
- (a) originally identical with the brigantine (of which word brig was a colloquial abbreviation); but, while the full name has remained with the unchanged brigantine, the shortened name has accompanied the modifications which have subsequently been made in rig, so that a brig is now
- (b) A vessel with two masts square-rigged like a ship's fore- and main-masts, but carrying also on her main-mast a lower fore-and-aft sail with a gaff and boom.
- A brig differs from a snow in having no try-sail mast, and in lowering her gaff to furl the sail. Merchant snows are often called brigs. This vessel was probably developed from the brigantine by the men-of-war brigs, so as to obtain greater sail-power.\n
