A brigantine is a vessel with two or more masts, at least one of which is square rigged. Brigantines originally carried both oars and sails. Now, a brigantine is principally a fore-and-aft rig with a square rigged foremast. Brigantines were the vessel of choice for Mediterranean pirates.

Schooner

Schooners use fore-and-aft sails on two or more masts and were popular with the Dutch in the 16th and 17th centuries. They were developed further in North America from the time of the American Revolution.

The schooner is distinctive in that the forward mast is shorter than or the same height as the rear mast.

Topsail Schooner

A topsail schooner is similar to a fore-and-aft schooner, but carries square topsails, and sometimes a topgallant sail on its foremast. A few topsail schooners are rigged with square sails on two of their masts. Such a vessel is called a two-topsail schooner.

Brig

A brig is a vessel with two square-rigged masts, with the aft mast acting as the main mast. To improve maneuverability, the main mast carries a small fore-and-aft sail.
