Here's a couple, and then I gotta put away sails. Barque- Square-rigged ship with 3 masts, and usually a riding sail on the mizzen. Brigantine(Brig)- Square-rigged ship with two masts, rear one taller. Schooner- Fore and aft rigged sails with two masts, both equal or rear larger. Ketch- Two masts, foreward larger, rear mast ahead of rudder post. Yawl- two masts foreward larger, rearward behind rudder post. Cutter- one mast, two or three foresails. Sloop-one mast, one foresail. Crew- Captain, the boss. First mate, next in charge Bosun- calls Sail and change orders on deck. Lines out crew. Not many more officers on a privateer. Zillions more on a Royal Navy rig.
