The stern of a ship is the rear part of the vessel. It is opposite the bow, which is the front. The stern is crucial for navigation and stability, as it houses important components like the rudder and propeller. These elements help steer the ship and control its movement through the water. In addition to its functional role, the stern often features various structures, such as the stern deck and transom. The stern deck can be used for activities like fishing or relaxing, while the transom is the flat surface at the back, which can also support additional equipment or features.
