The reduced positive boyance optional GWX mod

I'm trying it. It's all good but my depth seems to depend on more than speed alone. I'm currently at 85meters having ordered 120, at 1 knots! wow. Anyone knows what gives?

U-Boat lacks the necessary inertial drive to push itself downward. You are going too slow.

But shouldnt it mantain it's depth? If at one point i'm at 120 meters why should the boat ascend to 85 meters? It seems the deeper i go the more i will ascend. Oh boy

like I said 1 knot is too slow to maintain depth. If you had set 2 knots, you should have stayed put.

I always thought that an u-boat has zero buoyancy.:hmm:
In the book Das Boot it was said that the 'Regelzellen' were used for maintaining zero buoyancy.

Correct me if I'm wrong.

No its not true, U-boats had a slightly positive bouyance. That is why GWX models a positive bouyancy in them.

The meters you will rise when going slower than 2kn seem to fullfit a certain rate. As I tested it some time ago here are some examples:
set depth....rised to
...15...............12
...90...............73
..140............115
