Kort Nozzle animation

The above shows the idea behind the kort nozzle, looking down from above the unit. Whilst the propeller continues to turn the whole of the nozzle turns about a central axis. Water that is being drawn from in the front of the nozzle is then forced out at the rear in the direction that the nozzle faces. Water that would have otherwise have flowed in a straight line past the turned rudder has to follow the tube's shape.

The animation only shows the nozzle turning in one direction, but on the model it would also turn in the opposite direction.
