Docked Warship locations

[Marauder7]

Hi all. I was wondering if someone has cataloged the various ships docked in the ports. I have the U-Boat expansion but I'm currently playing the allied campaign. I love sneaking into ports and taking out as many ships as I can and scooting back out again.

My real beef is the utter lack of warships other than destroyers. I'm on my 8th patrol and I have yet to see anything other than 3 or 4 types of destroyers, mostly fubuki's as merchant escorts. Warship fleets always seem to be out of reach and always running at flank speed which my gato just can't match. Parking in known shipping lanes and waiting for them to come to me hasn't produced any results either except to increase the boredom.

I'm running stock with ship pack 1 and getting very bored sinking the same destroyer over and over again.

Any ideas where the warships are hiding?

Thanks
