SHIP RIB CALCULATOR
CUTTING OUT RIBS Many new captains building their first ship from scratch are uncertain how many ribs they can cut (or leave, if trimming out windows in a pre-formed fiberglass hull). Most all of the 1:144 scale model warship combat rules, having a common ancestry of IRCWCC, have the same rule that 15% of the length must be penetrable. Most allow up to 2" of solid area in the bow and 1" solid area in the stern. To use the tool below, simply select the classname of the desired ship and the rib width planned (most captains seem to prefer 1/4" ribs so that is the default). Then click the
button and it should display the number of ribs allowed along the length of that hull.
