AN49, yep there's dolphins there, found them as well, if they bother you dont go to AN49 go through AN47, you might run into a taskforce, I sank the Hood there once
as to what JU_88 said, I think it was in a book by Terry Pratchett where it was written:
"I don't like dolphins! Never trust an animal that Smiles all the time! it's planning something"
:hmm: that's probably why Kpt. Lehmann likes them so much, same evil mentality
