And that is why, even in clear, calm weather, I do a check every two hours (and turn 90 degrees to port, then to starboard).

Every hour in bad weather.

I admit I don't usually don my own "ears," but I should. I probably give up 10-15k tons a patrol when I don't (or get them, but it takes 10 days more).

I guess we all know this, but the detection hierarchy is pretty simple:

1. You manning your hydrophone
2. Qualified PO manning hydrophone
3. You on the bridge as WO
4. WO on the bridge as WO
