An aft is the back part of a boat, ship, or aircraft, or a direction meaning “toward the rear.”

Core meaning

  • In nautical and aviation language, aft means “near, toward, or in the stern of a ship or the tail of an aircraft.”
  • On a ship, moving “aft” means going toward the stern (the rear end), as opposed to “forward” toward the bow (the front).

Where you’ll see “aft”

  • Aircraft: The aft of a plane is the rear of the cabin or fuselage, opposite the nose.
  • Vehicles/engineering talk: Sometimes used more generally as “rear” vs “fore/front,” for example when describing front vs aft suspension arms on a car.
