Hello, Matt, it is a great day here.

 MM> They have been used on ships for at least a century.

 MM> There were no thrust bearings that could withstand the end thrust of
 MM> single-angled gears for the duration of a trans-oceanic crossing.

        I would like to see how this is done. I am trying to visualize
        this. I thought that most large ship had a straight out drive to
        the prop. The diesel maybe as they turn over at very low rpm but
        I can see where a turbine would need a step down box. The larger
        the prop the slower it turns.
