lol if only we have control over all that, hitting the silent running button supposedly does this, well it does, ive tested enough to see how things work under dc attack without it running, sub makes a lot of noise.

I believe the donation Narwhal may have a louded sound signature than say the Gato, which is fine, because it was a older, louded, slower boat.

Thanks for the link
