I have made the mod exactly for this use : naval warfare, without ground units. In the game editor, you can create "historical ships" for historical scenarios.
For the patch : the mod was tested only with no patched game. It appears that it works correctly with patch 2.0, but I did not test it for the patch 2.5 .
Sorry... Try to use the mod with 2.5 patch, for seeing. Perhaps, it works correctly.
The final version of the mod is awailable and I will not modify it because I'm working on a new mod (STEEL FIRE, very attracting for me because it may be played vs IA). If someone will take the job and work with STEEL NAVAL AMIRAUTE, the mod is now free
