It is the turbine. The crew says that it sounds more like an F1 car than a boat. Very pleased with testing so far. JT and I are taking it one step at a time. Making more changes before another session. Still trying to get my hands on a better video that I know is available.
All you can hear is the sound of the propellers cutting the water.....until you pass by. But other than that it's quiet as a church mouse.
