So I'm trying to understand how sea areas work, particularly concerning convoys and related matters. I'd appreciate it if anyone could tell me whether the below is accurate.
Sea areas are named, Hawaiian Islands, or Red Sea, for instance. They are made up of hex dots, which are more or less just like hexes except they are explicitly not for land units.
Each sea area has a concept of "sea boxes." Sea boxes are used to position units for search and combat purposes. The location of sea boxes is abstract, in that it doesn't have any relation to the hex dots.
Convoys are positioned in sea areas. As far as I understand it, the exact hex dots a convoy occupies aren't important, since they are notionally always in sea box 0 anyway.
Therefore, as far as I know I don't have to line convoys up hex dot by hex dot to trace routes across large sea areas, I just have to make sure the number of convoy points in each area is sufficient. For instance, in Global War, the U.S. has setup rules about the convoys to Japan, but the exact dots those convoys occupy doesn't appear to matter.
Is this about right? :)
