Checking Hydrophone

Last 4 patrols the weather was so bad all the time that I switched to the routine of "get into patrol zone, submerge, stop engines and wait for hydrophone contact". There's no point wandering on the surface when visibility drops to 300 meters...

Stop engines?

Back to the question at hand.

The following is from the Uboat Commanders Handbook:

"28.) This possibility of using the hydrophone to help in detecting surf ships should, however, be restricted to those cases in which the submarine is unavoidably compelled to stay below the surface. The hydrophone must not lead to inactivity [passivity] underwater, which would be wrong; it is an auxiliary instrument and no more, and can never be a substitute for ocular perception and surface viewing. As soon as visibility allows, the, place of the submarine is on the surface. Otherwise valuable opportunities of attack are lost."

How's that for an answer? Straight from BDU!

Well that might be true, but I bet you this handbook was written before the start of WWII or at least before '42 / '43.
Because believe me, in the later years of the war U-boat captains would never have been told 'the place for a submarine is on the surface'.
