What is the meaning of "aft" in nautical language?

In nautical language, the term "aft" refers specifically to the back or rear section of a ship. It indicates a direction or position toward the stern, which is the part of the vessel that is opposite the bow (the front). Understanding this terminology is crucial for navigation and communication on a vessel, as it helps crew members to provide clear instructions and ensure safety. Recognizing where "aft" is in relation to the rest of the ship is particularly important during maneuvers, docking, and when positioning crew or cargo.
