I lost interest and abandoned this project a couple of years ago. These days I spend most of my gaming time GM'ing D&D and Traveller on Roll20.
Thanks,

Control of a sea region means that you have the largest naval presence in the region.
To take over a coastal sea region, you must have the greatest number of naval attack points in the region.
If no nations have any vessels with naval attack points, the program checks submarine attack points.
If no player has any combat ships or submarines in the region, the program checks the ownership of adjacent land regions.
If one player controls all adjacent land regions, they will also control the adjacent coastal sea regions.
Control of coastal sea regions are checked at the end of each turn.
