I went in. 2 or 3 destroyers grounded themselves. There was a sub sunken at a wharf (manned underwater

-it was terrible storm & near zero visibility - I think the waves sank it), a docked destroyer which I sank, and an ASW trawler or similar vessel which I slammed with 2 torps so it was a raging inferno - but it never sank....
Don't think I'll go there again, however navigating past the nets was great fun using the obs scope, and I'm pretty sure there was a submerged wreck I had to avoid as well.
It's just the AI that stinks, not GWX.
