PICTURE

January ~ 14

The unused 180mm Archimedes screw thrusters were cut out and larger 300mm twin hydraulically driven, counter rotating prop ones installed.  Here the old ones are being flame cut out.

The below picture gives an idea in the change of diameter by way of the cut out piece. It is a little deceiving because the new one has extra material removed as part of the hydrodynamic shaping for improved water flow.
