 Like the hermaphrodite brig, a brigantine also has a main (second) mast made in two spars, and its large mainsail is also fore and aft rigged.However, above this it carries two or three square-rigged yards "instead" of a gaff topsail (the hermaphrodite brig retains the gaff topsail), and carries "no" square-rigged sail at all on its lowermost yard of its mainmast (the full-rigged brig retains a square-rigged sail in this position, making it very difficult to visually distinguish at a distance from a brigantine).Although superficially similar in appearance to the brig or brigantine, the snow is a much older three masted design which evolved from the larger fully rigged ship.
