Thanks for the advice and screenshots guys. Those are indeed some scary looking mines - realistic and well-detailed.
Last night, I hit a submarine net while surfaced (on purpose too - was kinda curious what would happen). I think I just took a small amount of damage, not sure. I apparently passed right over it (my speed didn't drop, but I heard a bang, and my crew said we're taking damage). I tried to circle back around to look at it, this time submerged, but got worried I'd take more damage, and resumed course.
Nice to see all the dials working too. I also like the more realistic clouds. I think my favorite change is all the new ship models and types.
Take care.
