Square Rigs
Brigantine - is a vessel with two masts whose foremast is made in three spars and square rigged like that of the full-rigged brig. The mainmast, however, is made in two spars and carries a fore-and-aft mainsail, above which are two or three yards on which are carried a square main-topsail and topgallant sail. 
Brig - is a vessel with two masts (fore and main), both of which are square rigged. The foremast is made in three spars and square-rigged. On the mainmast there is a standing gaff to which is rigged a small fore-and-aft sail. 
Barquentine - is a vessel of at least three masts similar to a bark with fore-and-aft rigging of the mainmast. The foremast is made in three spars in square rigging, but the main- and mizzenmast carry hoist-and-lower mainsails and gaff topsails of the schooner type. 
Barque or Bark - is a three-masted vessel with the foremast and mainmast square rigged and the mizzenmast fore-and-aft rigged. The mizzenmast carries no yards: there is a hoist-and-lower fore-and-aft sail and a gaff topsail. 
Full Rigged Ship - is properly, only a vessel of at least three square rigged masts, each composed of a lower-mast, top-mast, and topgallant mast. Each is outfitted with a yard and a full complement of square sails.

Schooner Rig - Fore and Aft Rig
Sloop - a small vessel with one mast and a fore and aft rig. The mainsail is attached to a gaff at the head and a boom at the foot and above it a gaff topsail can be set. Before the mast are one or more jibs. 
Schooner - is a vessel with two or more fore-and-aft rigged masts. The fore- and mainsails are suspended from gaffs and laced to booms on the foot of the sails. The first schooners had two masts, but the most popular had three. In modern times the number of masts has increased.
A variety of Two Masted Schooners 
Square Topsail Schooner - is a two-masted vessel, the mainmast of which has a fore-and-aft mainsail and gaff topsail identical to those of an ordinary schooner. Both masts are made in two spars, but the lower foremast is a little shorter than the corresponding spar of the mainmast, and the topmast is a little longer.

Rigging Basics
A Ship's rigging refers to the sails and masts she carries. This determines how the ship is classified.
Basic Terms
Spars -The rigid members which carry the sail of a vessel .
Masts - Vertical spars.
Yards - Horizontal spars which cross the masts.
Boom - A horizontal spar which is anchored on one end and extends the foot of a sail.
Gaff - A horizontal spar ( usually angled ) which supports to top of a sail.
Rigs:
Fore and Aft Rig - where the sails lie along the same plane as the ship's fore and aft line.
Square Rig - where the sails are rigged athwart (across) the ship. Lug Rig - Similar in arrangement to a square rig, except that the supporting spar is asymmetrically arranged on the mast, with a greater length behind than in front
Junk Rig - developed in the far-east. It is distinguished from other lug sails by the use of full-length battens which support the sail and give it an efficient performance at most points of sail.
Gaff Rig - The sail is set entirely behind the mast, supported above by a spar which extends upwards and backwards from the mast. There may or may not be another spar at the foot of the sail. This rig is effective at most points of sail.
Bermudan Rig -This is a triangular sail set behind the mast and often supported by a boom along its foot. The mast may be tilted backwards slightly to improve the rig's performance in stronger winds. The sail behind the mast is often supplemented by one or more sails attached to the forestays of the mast, such as a jib.
The most common are Fore and Aft Rig and Square Rig.
Masts
A ship's masts are named from bow to stern (front to back):
Fore-mast - the first mast, or the mast fore of the main-mast.
Sections: Fore-mast lower — Fore topmast — Fore topgallant mast
Main-mast - the tallest mast, usually located near the center of the ship.
Sections: Main-mast lower — Main topmast — Main topgallant mast — royal mast (if fitted)
Mizzen-mast - the third mast, or the mast immediately aft of the main-mast. Typically shorter than the fore-mast.
Sections: Mizzen-mast lower — Mizzen topmast — Mizzen topgallant mast
Bonaventure mizzen - the fourth mast on larger Sixteenth Century galleons, typically lateen-rigged and shorter than the main mizzen.
Jigger-mast - the fourth mast or the aft-most mast where it is smallest on vessels of less than four masts.
Sections: Jigger-mast lower — Jigger topmast — Jigger topgallant mast
Mast names for other vessels generally follow this naming.
