Warships

[Tnchi2a]

So I've looked for quite a long time.
So I'll ask here if anyone has found or created a ruleset for large ships.
I have the Nautical/Aviation Handbook, but the rules in the book are more geared to the Aviation side.
And the rules in the Corebook are more geared to small boats.
What I'm looking for are rule for ships such as Cruisers, Destroyer, Etc.
