Vessels have more usable controls and more realistic ones, unlike Ship Simulator 2008 in which only the whistle, binoculars, thrust, rudder and thrusters (if applicable on the vessel) are usable, although you can listen to the ship's radio but not send out calls. Sinking dynamics and physics have also improved in Ship Simulator Extremes.
