Aaron, thank you, I had completely forgotten about those rules. I will have to increase ranges to play in the garden, but they are perfect for the tabletop.
I should have said at first the rules I needed were for sail. However, sometime in the near future I will need rules for the interwar period for ship to ship actions, although it will need to be for 28mm figs and ships. A destroyer versus a commerce raider, or smuggler, or submarine or a combination all for the garden except for boarding actions.
