Additionally, you can get your merchant convoys through to augment the CP production. As I have posted a couple of other places, if you load the AUTOSAVE file at the start of each turn (a pain I know), you will discover the AI hasn't moved your convoys for you ... you can choose their routes. Most importantly, reroute the South Atlantic convoys to the west and north of the British Isles, especially keeping out of cruser visual range of Scapa Flow. Concentrate the German Grand Fleet against the Russians to wipe out their navy and secure the Baltic trade route.
Amtrick,
I have not tried the above convoy strategy yet in SP, "I find it interesting that we are even able to do that", also I am kind of surprised the AI has not picked up on it. In MP your strategy is a "NO GO", for there is no AUTOSAVE file, thus being stuck with CP merchant convoys trying to make the English Channel kamakazi route. Would love to be able to have other merchant ship options for both sides in MP.
