Sure, this is not classified...Normal lockout occures at periscope depth, which puts the deck of the sub at about 45 feet. That can vary depending on wave action and the subs ability to maintain trim. the lock is flooded first then pressurised to match sea pressure, otherwise the hatch could not be opened. No saturation diving for me, that's a competely different expertise than mine.

Thanks Dave. 45 feet doesn't sound too bad. I was thinking it might be different if done at deeper depths, but it's not normally done that way so...
I hadn't even thought about the wave action. I did a boat dive off of Laguna Beach once. Seas were like eight foot or so. Getting off and especially getting back on the boat was thrilling. I bet that's really fun on the big seas.
