There were a number of limited hydroplanes that were prop-riders prior to the Slo Mo Hydroplnae being built.

Speed is increasing, all is good. Here is the really bad news. So, we need to keep the prop in the water. Unlimited hydroplane first is that lift goes up with speed, but much faster than speed.

This will force the outside boat to run unlimited hydroplane longer course potentially slowing them down and allowing the slower boat on unlimited hydroplane inside to win.
