I have a copy of GW's Man O War rules but none of the ships. I was wanting to try it out as I've heard it's an excellent set of rules for naval warfare. Are there even any other fantasy naval games out there? So I was thinking of scratchbuilding some ships to play with. What sizes(lenght, width) and scale are the MoW ships?I just need rough estimates of sizes for ship classes but exact examples would be good too.

On a side note would anyone be interested in buying fantasy style ships if they were available?
