Just saw a TV program"Build it Bigger" and they were featuring the Geico off shore power boat racer,
Twin turbine helicopter engines in a cat hull out in saltwater off of Florida. those of you who follow the Thunderboats knows all the trouble saltwater can bring
During one test they were clocked at 170mph !! with more throttle to go
They managed to luck out and win the first race of the season when the new Budwieser boat lost an engine and was out of the race
God I love those big boats
