What is the Other Name for Lateral Propulsion on a Ship? Bow and stern thrusters are lateral propulsion devices installed on a ship to improve maneuverability, especially in tight spaces like harbors or docking areas. • Bow Thruster: Located at the front (bow) of the ship, this thruster helps push the bow sideways (port or starboard) without using the main propulsion system. • Stern Thruster: Located at the rear (stern) of the ship, this thruster assists in moving the stern sideways. These thrus
