Periscope depth question

virtualpender · 05-04-10, 11:08 PM

I had the chance to visit the PAMPANITO over the weekend and noticed the shallow depth gauge in the control room had markings at the following depths:

48 1/2'
66 1/2'
150'

I'm assuming the 150' is the "crash dive" depth. I am correct to assume that the other two values are the minimum and maximum periscope depth and that the middle value between the two (57 1/2') is the standard periscope depth?

Here's a photo (not mine - this one is from COBIA) illustrating what I'm asking about. Anybody know for sure?
