Using Real Navigation, with my written KTB:

- Each time I plot a new course to a waypoint, I calculate an ETA and set my alarm to the estimated clock time.
- My Navigator does regular Dead Reckoning readings, and I use them to correct both my course and my ETA.
- When the alarm rings, I slow down to ahead one-third and order my Navigator to make a Celestial Navigation reading.
- When the Navigator is done, I dive to 20-30 meters to initiate the hydrophone scan protocol.

I know their is an automated routine for patrol grids, but in the Polish waters I prefer to keep control. Feel free though to improve my routine, though.

Fwiw, I've never been able to find any proof that actual commanders did a hydro scan protocol on a routine basis. Lot of water out there; needle in a haystack
Maybe someone else has ?
I.e., Kretschmer did a daily routine early morning dive but that was to give the watch crews a break from that taxing job vs. for a hydrophone check.
Of course a check can be a side benefit of such a routine too.
