Ahh gee fellows. Don't blame me for everything. :-) I did not invent it. The Society of Naval Architects and Marine Enginers proposed a standardized presentation format for model resistance in "Explanatory Notes for Resistance and Propulsion Data" which includes the fatness ratio (Volume displacement/(0.10L)^3 . They also include the displacement/length ratio (They call it the fineness ratio - go figure) for North Americans more familiar with the dimensional term. Because I live in Canada where we use metric units but design for US builders etc. I prefer the non-dimensional terms.
