18th C Indian Ocean Voyages

Math and Science at Sea

There were numerous people involved in navigating these ships -- most French vessels of this size had 3 navigators (pilotes), at least one of whom was expected to be an expert in long-distance sailing. (One of the others would specialize in coastal sailing and was expected to be knowledgeable about the particular harbours along the way.) These pilots also had 'pilot's mates,' younger men whom they were training. Certain officers were also interested in learning how to calculate the ship's position from the sun and stars. At noon, all of these men would gather around the binnacle (which housed the ship's compass) and make observations. They often compared their findings with their peers, and this group work acted as a corrective if their findings were too far off.
