Am I doomed?

But this looks like "stop" on the telegraph.

Even without those mods depth keeping was tricky - my sub kept wanting to slowly rise over time. I guess my chief over-trimmed the tanks as a safety precaution.

The most unrealistic part I think was getting rammed and the destroyer blowing up and not much happening to us.

I vaguely remember this bug from stock SH3 days - you could ram an enemy merchant with your conning tower at full speed and destroy it with minimal damage to your sub. In reality it probably would have sheared the tower off of the sub and sunk it!

Are you using GWX? IIRC, GWX gives the sub a slight positive buoyancy. NYGM trims negative, and stock, I have heard, is neutral. Slight positive buoyancy is generally safer. But silent running adds an additional problem. Pumps are shut down, and there is always a slight inflow of water, making the sub gradually heavier. Plus, at depth, the pressure hull is somewhat compressed, decreasing the internal volume and lowering the buoyancy vice what it was at/near the surface. The result is that the boat drifts lower with time. To compensate, you must increase shaft rpm and/or turn on the pumps. Either alternative increases your sound signature. Stiebler's Slient Running Fix simulates this, regardless of which megamod you are using. It works whether the boat is initially trimmed positive, neutral, or negative.

I believe there is at least one mod which addresses the ramming damage issue, but don't know offhand which it is. Of course, USS Growler famously survived a collision which sank a steel-hulled IJN patrol boat. Growler was a Fleet boat, and collision survivability might be comparable to a Typ XXI. But Growler took serious damage, although still (somewhat) capable of submerging.

Cheesy? Yebbut, cheese tastes better than salt water. Savor it!
