Also BTW, and speaking of the Guiness book and alternate drives, the Uni of
California in San Diego broke the world record for alternate propulsion by
over half a knot with their mammal-like tail drive.  Congratulations to

Wade, I don't know the numbers, but the Naval Academy boys ran a very tidy 
little HPS with twin bladed counter rotating props about a yard across and 
stomped the competition into a mud hole. I'll bet some budding Admiral used 
it for a dissertation, in which case, it's probably on the web somewhere.
