43. Can submarines remain stopped when submerged, without lying on the bottom?

A very well trimmed boat may do so for about 5 minutes at a time by juggling with her periscope. For longer periods it is only possible in a few localities where layers of different density. occur in the water, e. g., in the Baltic, Cattegat, and Sea of Marmora, where occasionally a boat may lie submerged almost indefinitely1 with all machinery stopped, resting on a layer of salt water.

1 Two German submarines, sent at outbreak of war to watch the southern exits from the sound and Great Belt, succeeded in thus lying submerged, with their motors stopped most of the time, for about 23 hours out of the 24, on 7 consecutive days.

Ah yes, but there has been some lively debates on the subject as well.

I don't feel I'm gaming reality if I stop my sub for short periods - less than 5 minutes. The above vindicates my mode of operation.:p

PS. Did you check the date?

Yes, because it's a game.

Though there are optional mods that prevent it.

They mention that juggling the periscope can help the sub stay put for a few minutes...how does the periscope come into play? As a sensitive way to displace a little more or less water?
