I can't prove this but: If you can see it from a submerged periscope, you should most certainly already be hearing it. Submarines relied on sound--not as much as they do today--but sound was still their eyes when submerged. Not many skippers would be happy with his scope ten feet under the surface to notice the massive hull of a ship coming into focus. By the time you saw it, it would likely be too late to react. A ship doesn't have to hit you to ruin your day. The prop wash of a freighter going over you can suck you to the surface, even if you're at 90 feet.

I think that if the scope was up, it was out of the water.

And keep thumping that bass Sailor Steve!!!!
