Faster Crash Dive - when an aircraft or warship etc is spotted and a quick crash dive is needed, it may take an agonizingly long time for your chief engineer to run from wherever he is to the ballast valves and operate them. so follow these steps instead of ordering a crash dive from the depth gauge.
(1) press the space bar to pause the game (2) select whichever officer is standing at the navigation table (3) order that officer to operate the ballast valve (4) NOW order the crash dive. (5) set engine telegraph to fastest possible speed. (6) resume normal game speed
You'll be under in a more reasonable 20-25 seconds
