== Capsize Risk ==

[Based on sail boats]

Capsize Risk = B/(D/[0.9*64])^0.333

The Capsize Risk is a seaworthiness factor derived from the [http://www.sailingusa.info/formula.htm USYRU] analysis of the disastrous 1979 FASTNET Race, funded by the [www.sname.org/ Society of Naval Architects and Marine Engineers]. Values less than two are good for sail boats. No comparable data exists for displacement boats.
