It had two of three masts with triangular (lateen) sails. As time went by it increased in size with a square sail on the foremast and lateen sails on the others.
  5. 5. Caravel The square and triangular shape combination of the sails gave the ship the ability to sail close to the wind, this was essential if successful voyages were to be made in regions where the wind pattern was unknown. Sailors could now handle the ship better at sea

  7. 7. The stern-post-rudder Helped sailors to maintain a steadier course.

  10. 10. The Astrolabe Was used to tell the location of the ship at seas using lines of latitudes. The astrolabe was used to observe either the altitude of the sun at midday or the altitude of the polar star at night.
  11. 11. The Astrolabe Itconsisted of little more than a graduated metal circle with a revolving pointer and a turning board in the centre.
  12. 12. The Quadrant
  13. 13. The Quadrant Thiswas a graduated quarter circle of wood, with sighting holes mounted on one edge, and a plumb-bob hanging from the apex. This was used to determine the location of the ship at sea.
  14. 14. Invention of printing
  15. 15. Invention of Printing With the invention of the printing press information about geography, science, literature and news could be copied and passed on easily in the form of books, charts and maps.
  16. 16. Weapons Theearliest guns were probably produced by the Arabs in North Africa about AD 1250. These were soon copied in Europe and by the 15th century gunpowder and guns of all description s were widely used. Caravels soon carried cannons.
