Miss America X

I am fascinated by the early generation of high-speed powerboats from the early part of the 20th century. These vessels had some interesting features such as bow rudders, low deadrise stepped hydroplane hulls, wood construction. The most outrageous example was Miss America X with four 1800 hp Packard V12 engines which were later used in PT boats. Fitted with a 300% step up gearbox driving 16 inch propellers, I sometimes use this boat as an example for clients as one end of the spectrum on how speed effects optimum propellers diameter (the other end is a tug boat)

This collection of you tube videos is a fascinating collection of primary source material which has a little bit of something for everybody. My petrol head friends should listen to the first video as the noise of a boat powered by 4 V12 engines is excellent. My wooden boat friends will appreciate the construction but went into one of these monsters.
