NOTES
Many innovative features were incorporated into the design of Britannic. The most outstanding of these was her adjustable screw propeller shaft. After leaving port, when the vessel entered deep water, the aft section of the propeller shaft was lowered, allowing it to run in smooth undisturbed water thus increasing, in theory, the performance of the vessel. In practice severe vibration and constant breakdowns meant that after several voyages Britannic was sent back to her builders for conversion to the standard design incorporated in her sister Germanic (Yard No. 85).
