Boatswains, within the British navy, held a vital role during the time period that David Grann explores. They acted as officers responsible for the upkeep and maintenance of a ship’s hull, which forms the structural body of the vessel. In the course of their duties, they both oversaw and actively handled various aspects of the ship’s operation. This included managing the ship’s flags, sails, rigging, and the smaller boats stowed on board. Their expertise and skills were crucial in ensuring the smooth functioning and maneuverability of the ship, making them indispensable members of the naval crew.
