Motor HP

[Martin Sanderse <sanderse@interlog.com>]

Someone asked what power it takes to go how fast.

I made up this chart some years ago based on what I read about WWII mini-subs.  Ray goes 
very fast on his power (5 HP wasn't it?)

I suppose the thing to remember is that the more water you enclose, the more inertia you 
have to overcome to stop and accelerate.
