That would have been the aim for serious builders. If you are looking to buy to race I would suggest not considering any A more than 2kg over. Things to look for that could add weight are significant repairs to hull or mast and overly heavy fittings and foils. Weighing the boat is the best thing to do. If you can't get hold of calibrated scales, two good bathroom scales will get you in the ballpark. Weigh the boat mast down with everything as the boat would be sailing on the platform. Doesn't include extras such shackle key, water bottle. gps, starting watch etc.
