Wargaming rules for WW2 naval battles. This set of rules has been developed to give a reasonably historical result for a large fleet action in about three hours of playing time Scales and time Each game turn is calculated to be about 15 minutes and 1000 yards equals one inch on the game table. This game scale works best with 1:3000 scale models. For larger scales such as 1:2400 or 1:1200, double all measurements. For 1:6000 halve all measurements.
