SUBSIM Radio Room Forums - Good Battle of the Atlantic Wargames? Tabletop or Computer

I've become interested recently in wargames of a more strategic nature than the mostly tactical sort I've been interested in most of my life. While searching for something that looks at my favourite area of interest, The Battle of the Atlantic, I've found not much. I'm thinking of something on a computer that's either like CMANO/CMO or Rule the Waves or I guess more Gary Grigsby-ish such as the Eagle Day to Bombing the Reich title that basically does for the strategic bombing campaign what I want to do with BDU. A tabletop game would be interesting to me too.

However I haven't been able to find much that isn't like solitaire wargaming a solo commander or the familiar computer games we all know and love that have their own sub forums on this site.

Anyone have recommendations? Old and new welcome.
