Yes, I just wish convoy zones would have been but in the game in the first place like AAE. That was a great idea to get the Battle of the Atlantic in the game. AA50 should have been AAE and AAP combined with a few modifications. Still looks awesome though. I see IL has come up with a convoy system in his AA50 house rules. I think the simplest way to do it would be to be key sea zones and put control markers in them. If an enemy unit enters it you cover it with your marker. Each convoy could be worth 1 or 2 IPC’s. Depending on what worked better. If you get it back then remove the enemy’s marker.
