Scapa Flow GRRRRRRR!

[ChrisD]

So I just downloaded SH3 (after much time enjoying SH2, AoD, etc). I'm at 79% realism (not ready to id and manual TDC yet). I was assigned to the map sector that contains Scapa Flow. There are no instructions other than what sector to patrol, so I figure this is my opportunity to pull Gunter Prien's legendary feat. I end up making it all the way in (2 DDs sunk, many others eager to meet me) with only a couple of torpedos left. What do I find?? NOTHING. Not a single capital ship to be found. What's the deal?!?!?! I tried to shell the Scapa Flow lighthouse, and hit it perfectly, but the light continued to shine.

Also, when I sank one DD, it ended up sitting vertical in the water, with its nose on the bottom (very shallow water), then it just disappeared. I was going to use it for cover, but it vanished as soon as the nose hit the mud. Is there any way to keep sinking ships around a bit longer if part of them is still on th surface?

Also, my auto TDC seems to do a terrible job. I read about opening the doors, which I'll try, but I found two HUGE convoys and missed all but one shot. Is there a secret to torpedo setttings in very rough weather? Any help would be appreciated.

Thanks
