Image: In this photo, we are looking aft toward the stern. Between 1492 and 1543, Spanish mariners were engaged in world-wide discoveries and in plotting navigation routes. In 1543 Spain established its navigation system, which was fully encoded by 1561. Beginner in this latter year, the galleons were required to travel in a fleet (Spanish = una flota), thus taking into account patterns of corsair attached by the British and French and weather patterns, most especially, of course Atlantic and Caribbean hurricanes and monsoons in the Pacific and Indian Oceans. In Spain, las flotas originated in Seville (Sevilla) until 1717, and thereafter they sailed from the port of Cádiz (linguistic note: stress the name of this city where the accent mark lies). Taking an average of 40 days to cross the Atlantic, therefore, the flotas usually set sail by early August.
