Hello, <br> The newer hulls weigh in 15 lbs lighter then the older ones. The questions you have to ask yourself is what type of racing do you want to compete in? Do you want to finish first or are you just looking for a good time. I know I just junked 1979 hulls because they were de-laminated and just horrible. Are yours salvagable? New sails help of course, but if you haven't beaten yours up then why waste the money. I think the bottom line is how competitive you want to be.....<br><br>
