All this with no hull damage (100% integrity).

"Buoyancy and fine-trimming your depth

• The speed at which your U-boat is traveling can affect your depth.

• A U-boat that is non-moving or operating at 2 knots will run about one meter or so above its commanded depth. The top of the conning tower may broach the surface if you were at or just above periscope depth. This could result in ships or aircraft spotting your U-boat if they are in range.

•A U-boat operating at > 2 knots will be unaffected

• GWX varies your U-boat‘s buoyancy after a close depth charge detonation. This may result in your U-boat being temporarily blown to the surface by a depth charge exploding underneath you, or being driven deeper by depth charge explosions just above you

• Flooding will force your U-boat deeper to reflect the effect of flooding on your U-boats buoyancy and trim"

- GWX Manual v3.0, page 48

As I said in my previous post, I have not personally observed the positive buoyancy behavior described in the manual. In GWX, my VIIC can hover like a Huey. Nor have I experienced the lack of depth-keeping you describe. I can only guess that some other factor - perhaps another mod - is contributing to the behavior you describe.

Do you use the Stiebler patches?
