I have some ships in my 1/3000 scale WW2 collection that unfortunatly don't have any rules in ruleset of choice, Victory at Sea, so I've done something about it and written my own.
Go here to download a PDF for the Royal Yugoslav Navy in WW2
Go here to download a PDF for Abdiel (UK) and Pluton (French) classes of Minelayers
The minelaying rules are basically taken from this post by David Manley (I hope he doesn't mind me repeating them) over at the mongoose publishing forum (he also has an excellent victory at sea site), but the ships stats are my own creation.
