Twin-screw vessels have following advantages:

  1. While underway, side forces of rotating propellers are eliminated as each propeller rotates in a different direction.
  2. While maneuvering, a twin-screw vessel has more advanced maneuverability, than single-screw, due to additional steering effect of two propellers capable to rotate at different speeds and Ahead/Astern directions. Twin-screw vessel able to change its course to any heading at the same position.
