I have been doing some reading, and I actually don’t think this is the case. Apparently Parsons was experimenting with geared turbines in ships from the Turbinia in 1897. In 1909 he bought a triple gear expansion ship and ran it for some time to get a baseline before inverting it to a feared turbine system. By 1910 it had sailed over 12,000 miles with no problems or wear on the gear teeth. He was continually increasing the size of the ships he could build them for.
