On a cruise ship, the captain is the most important person in charge! Think of the captain like the boss of the ship. They steer the ship and make sure everyone is safe.
But the captain has help! There are other important people called officers and crew members. Officers help the captain by taking care of different jobs, like making sure the ship is going the right way and looking out for other boats. The crew members help too! They clean the ship, cook food, and help everyone have fun on their vacation.
So, the captain is the leader, but lots of other people work together to make the cruise ship a happy and safe place!
