Hi , Could you give me the Ixx for the mast you are selling ? The boat I will be building will be a Horstman Tristar 31 , it calls for a 37'3" mast , 8.5" Iyy and Ixx 19" . I will be scaling it up length only 6% . I can scale overall beam only , not hulls , if it will allow me to use the 40' mast . I will have to get the math on scaling mast . Thank,s . Rick .
