I agree! I don't see how you can set everything for a max-rate of dive and expect to abort that half-way through and level off at periscope depth, or even 30 meters for that matter. That's a
lot of inertia driving you at that point.
I've never read of an account where a dive was started intentionally without a properly functioning green board. I'm almost positive that that's considered 'against the Book'. But I have to wonder if that didn't happen in wartime a lot. Shaving seconds here and there might be risky, but so is being a sitting duck half-submerged as ashcans rain down around your ears.
I've seen several war footage videos on-line (mostly on youtube). Mostly they've been propaganda ones. From the films it does seem as if they're already setting dive planes and flooding tanks even while the watch crew is still clearing the bridge. As an open conning tower hatch would definitely red-light the board, it appears as if they
are starting to dive without a full green board.
With regards to SHIII, the game certainly lets you start a dive without full green. There's no way the diesels should run as long as the game has them run. The main induction (the air intake that ventilated the submarine on the surface, and in particular, supplied external air to the diesel engines) is one of the biggest --and potentially fatal-- openings through the pressure hull, and diving with it remaining even partially open is deadly.
The S-5 sank due to the main induction being left open. That sinking was also the driving force to design and implement automated indicator boards (the Christmas tree).*
I'll keep researching. :hmm:
