[dave davis]

YRA allows the main to fit the following dimentions:
MGU=The greater of 0.28*E+0.016*P+.85ft or 0.38*E
MGM=The greater of 0.5*E+0.022*P+1.2ft or 0.65*E
Taken from PHRF Northern Ca- YRA Par VII
The sailmakers in the Northern Ca area will make sails to meet these rules for boats like C34's
Contack me if you need some additioal info
Good luck'
