It contains information on the rules of marine science, shipping using sailing equipment and their accurate calculations, description of the compass and its parts, identifying the ship route and latitude and longitude lines, tables of mileage, celestial bodies, drawings of some ports that he saw. There is no doubt that many of these ports have been abandoned and changed due to climatic factors and political, social and economic conditions.
