"A galleon. On its way from the Spanish Main. They're approaching with oars."

A galleon was a large, multi-decked sailing ship used primarily by the nations of Europe from the 16th to 18th centuries. Whether used for war or commerce, they were generally armed with cannons.

The galleon was an evolution of the caravel and carrack. A lowering of the forecastle and elongation of the hull gave an unprecedented level of stability in the water, and reduced wind resistance at the front, leading to a faster, more maneuverable vessel. The galleon was powered entirely by sail, carried on three to five masts, with a lateen sail continuing to be used on the last (usually third) mast.
