A podded engine is a type of propulsion system for ships, typically consisting of a gas turbine or diesel engine mounted inside a streamlined pod, or nacelle, which is then attached to the ship's hull. The pod contains the engine, gearbox, and propeller in one unit, allowing for greater maneuverability and improved efficiency. The pod can be rotated 360 degrees around its vertical axis to provide thrust in any direction. This type of propulsion system is becoming increasingly popular on modern ships due to its simplicity and flexibility.
