Redfoot, I'm with you. I usually 'forge ahead' to the patrol area and get that 24 hour thingie out of the way. However, if I run into a lone merchant in my path, I try to dispense him with my deck gun crew. Once the 24 hour thing is satisfied, I'm seriously on the hunt, and on my way home.
I'm still early in the war so hunting is still fairly easy. I'm all about handing out awards, promoting guys, and acquiring new (and skilled) crew. Hope I can hang on and get a better boat (though I started out in a type VII).
