This chapter discusses mathematical models for control forces and moments. A surface craft is usually controlled in surge, sway and yaw while cargo ships and passenger ferries also have systems for roll damping. It discusses the following systems: propellers as thrust devices, ship propulsion systems, USV and underwater vehicle propulsion systems, thrusters, rudder in propeller slipstream, fin stabilizators, control surfaces, control moment gyroscopes, and moving mass actuators. The two main types of propellers available for ordinary merchant vessels are fixed‐blade or fixed‐pitch propellers and controllable‐pitch propellers. Marine propulsion is the mechanism or system used to generate thrust to move a ship or boat across water. Small USVs and underwater vehicles use propellers for propulsion, maneuvering, attitude control and dynamic positioning. A thruster is a device for propelling a marine craft. It is a more complex arrangement than a single propeller.
