Speed and quiet - 1/3 vs 2/3 vs full stop

Would also be pretty cool if you could put the boat into turbo-electric mode or use the EPM. My understanding is that the EPM is pretty loud though.

We actually did this once down in AUTEC. We entered the range and scrammed the plant out. We turned almost everything in the boat off, including the fans.

With the EPM you are not going to be winning any speed races and you are VERY range limited but you will be a hole in the water. They tracked us by the LACK of noise in the water. We ran the range and then had to recover the plant and bring the boat back on-line quickly. It was quite the experience.

It was QUIET in the engine room. Scary quiet.

The outboard?? That would be for maneuvering in port. In theory you COULD use it to go somewhere if you have a propulsion train casualty, but that would be a LONG, LOUD, and SLOW. That was a screaming banshee as someone said earlier.
