The seeming discrepancy comes about for the simple reason that ships cannot go fast enough to have that effect.
Never thought about this before - but now that I do, I'm wondering if SH3 (and no doubt naval sims) model this effect...? I have a feeling SH3 does, and will check it the next time I play.

Just found some info about ship turning circles here (not read it yet)

Makes sense.

I think I recently read a post here on Subsim about a mod which reduces periscope visibility and usage at higher submerged speeds.
