how do pirate ships sail against the wind
Sailing into the wind Sailing into the wind is possible when the sail is angled in a slightly more forward direction than the sail force. In this aspect, the boat will move forward because the keel (centerline), of the boat acts to the water in as the sail acts to the wind. The heeling force of the sail is balanced by the force of the keel. This keeps the boat from moving in the direction of the sail force. Although total sail force is to the side when sailing into the wind, a proper angle of attack moves the boat forward.[1]
Spanish Armada In September 1588 the Armada sailed around Scotland and Ireland into the North Atlantic. The ships were beginning to show wear from the long voyage, and some were kept together by having their hulls bundled up with cables. Supplies of food and water ran short. The intention would have been to keep well to the west of the coast of Scotland and Ireland, in the relative safety of the open sea. However, there being at that time no way of accurately measuring longitude, the Spanish were not aware that the Gulf Stream was carrying them north and east as they tried to move west, and they eventually turned south much further to the east than planned, a devastating navigational error. Off the coasts of Scotland and Ireland the fleet ran into a series of powerful westerly winds, which drove many of the damaged ships further towards the lee shore. Because so many anchors had been abandoned during the escape from the English fireships off Calais, many of the ships were incapable of securing shelter as they reached the coast of Ireland and were driven onto the rocks. Local inhabitants looted the ships. The late 16th century, and especially 1588, was marked by unusually strong North Atlantic storms, perhaps associated with a high accumulation of polar ice off the coast of Greenland, a characteristic phenomenon of the "Little Ice Age".[50] As a result, more ships and sailors were lost to cold and stormy weather than in direct combat.
