What is the term for the rear part of a ship?

The term for the rear part of a ship is "stern." This is the section that is opposite the bow, which is the front of the ship. The stern is crucial for navigation and maneuvering as it often houses the steering mechanisms and propulsion systems. Additionally, in maritime terminology, the terms "forward" and "aft" are used to describe positions on a ship; "forward" indicates a direction toward the bow, while "aft" refers to movement toward the stern. Therefore, "stern" is the specific term that designates the rear part of a vessel, making it the correct answer.
