Frequent hull appendages contain propellers for propulsion, rudders for steering, and stabilizers to quell a ship's rolling motion. Other hull options is often connected to the vessel's do the job, such as fishing equipment and sonar domes.
In combination with conventional fastened and controllable pitch propellers there are plenty of specialized versions, for instance contra-rotating and nozzle-model propellers. Most vessels have an individual propeller, but some substantial vessels could have up to 4 propellers supplemented with transverse thrusters for maneuvring at ports.
