Patax

A patache (occasionally "patax" or "pataje") is a type of sailing vessel with two masts, very light and shallow, a sort of cross between a brig and a schooner, which originally was a warship, being intended for surveillance and inspection of the coasts and ports. It was used as a tender to the fleet of vessels of more importance or size, and also for trans-Pacific travel, but later began to be used for trading voyages, carrying cargo burdens of 30 tons or more.
