Developed for convention games, this is a set of rules for naval battles 1906-18 that can be played either with miniatures (1:6000 scale is recommended) or counters.
Only battleships, battlecruisers, and the most heavily gunned armoured cruisers are directly represented; the impact of smaller vessels - which was generally minor when capital ships clashed - is represented by the event table.
The rules are fairly abstract and large battles can be fought out in a few hours.
