Yes the "naval" gener in wargaming is some what forgotten to some extent, same as the "cold war" era. Although we recently have "Armored Brigade" as a cold war playthrough.
As a fan aswell for "maritime" warfare as it makes use of "combined arms", all I can suggest is that you have a look at CMANO (Command Modern Air Naval Operations), or in other words, what was once "Harppon3" for PC. Although itīs not WEGO, as itīs a RTS, you can spend ages playing CMANO and itīgets alot of updates too.
I like it so much, as I was once a big fan of Janes "Fleet Command", that I have even went for the real deal, which is itīs boardgame version. Iam currently waiting to recive a mint copy of "The Admiralty Trilogy" (Clash of Arms) "High Tide" miniatures rule set which uses the Harpoon 4 rules, in this case v4.1 of the rules.
The Admiralty Trilogy:
BGG: High Tide...
Or you can go for the "Command at Sea" series which is focused on WWII...
Another alternative for PC is "Juntland" by Storm Powered which is on sale today...
Itīs a old engine but still a good one. Canīt say how good is support and/or if itīs even active but do take in mind that you do need the Storm Powered app to run/launch the game and it does use a DRM system!
