The fullness of ship forms, as measured by the block coefficient Cb, has for many years been a point for discussion. Today, using computers, the optimum Cb can be accurately calculated for any particular type of ship and trade for any optimality criteria. An empirical value of the optimum Cb is however always useful even in an optimisation calculation where it can be used as a check on the computer results. In other cases where a computer optimisation is not available, the empirical formula may provide the only guide. In this article one or more empirical formulae for Cb, which it is believed is of general use for all types of ships is presented. The new proposed formula has been calculated with the aid of a computer program and data of about 200 ships of various types built in the last decade. The formula found by regression analysis is purely empirical. (AUTHOR)
