I don't know for sure, but I strongly suspect that the Mount went faster than 15 mph back in the 50's since her engines were usually run up around the 450 rpm level. Nowadays, although they're still capable of 450, 405 rpm is the normal max. Plus the routes are now shorter than they were then.
Those of you who remember a larger wake back then are right. Her wake got smaller when she was lengthened. She got longer, but not wider. Also, the new section actually increased buoyancy, requiring several tons of concrete ballast to bring her back down to the proper water line.
