Ahmad ibn Majid

[citation needed] Ibn Mājid wrote several books on marine science and the movements of ships, which helped people of the Persian Gulf to reach the coasts of India, East Africa and other destinations.

Most of his navigational calculations depended on sophisticated astronomical observations, especially using the lunar mansions (manāzil al-qamar) and the thirty-two stellar rhumbs (akhnān).

Arab sailing was at a pinnacle during Ibn Mājid's lifetime, when both Europeans and Ottomans had only a limited understanding of geography in the Indian Ocean.

His Kitāb al-Fawāʾid was widely utilized by Arab sailors, and comprised celestial navigation, weather patterns, and charts of dangerous areas in which to sail.
