[Paddlewise] Fatness ratio

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.
Cheers
