Bladerunner's post re Theoretical Hull Speed set me thinking about Multihulls. I seem to remember something called the Herreschoff Coefficient which is a length / beam ratio above which a multihull is not limited by wave making resistance and hence has no theoretical upper limiting hull speed. The figure of 15:1 comes to mind. Is this figure correct? Also, reason would suggest that there should be a gradual reduction in wave making resistance rather than a cut off point at a particular length / breadth ratio?
Sorry to be a bore, but I'm waiting for the fog to lift.
