In reality, there were two decks awash procedures. One was to leave the diesels running, the other was to be a bit deeper and use electric motors.
We can do both in the game. Like you I like to be decks awash with diesels running. My most urgent need is have fully charged batteries at all times. This reduces fuel use and gives me a fully combat ready submarine that can remain submerged for the longest possible time if it is necessary for survival.
There have been limited numbers of times where I came to the surface for thirty seconds or so to get a radar fix. Then I will typically come to 37 feet or so, get the fix and submerge again. In this case the important thing is to keep visual signature as small as possible. Since I came from an environment where I could be detected on sonar, it doesn't matter that I still can be as I pop up for a peek.
