Captains and crew members are assigned to ships through the Shipyard interface by clicking on the plus sign under the ship stats at the top of the window. At any given time, a ship may have only 1 captain, but may have up to 5 crew members assigned to it. Captains and crew members add their stats (Morale, Combat, Seafaring, and Speed) to those of the ship to determine a voyage's chance of success. They may also possess other traits that affect the rewards for success or penalties for failure. Using the Lifeboat perk from port Random events can save a captain or crew member from death.
