R/C Naval Combat

I believe that at the time Kotori87 was running his torpedo cruiser the WWCC was allowing 2 balls per barrel. also his ship was set up so the balls would hit the water line when he fired at just a few inches from the target ship. The result was to regularly put 6 quarter inch balls in a 2 X .5 inch area below the waterline and take out the hole section. Six separate .25 holes have an area around 1/3 of an inch. One 2 x .5 hole has an inch of area to let water in.
