 Sailing ships became longer and faster over time, with ship-rigged vessels carrying taller masts with more square sails.Other sail plans emerged, as well, that had just fore-and-aft sails (schooners), or a mixture of the two (brigantines, barques and barquentines).Cannon were present in the 14th century, but did not become common at sea until they could be reloaded quickly enough to be reused in the same battle.
