Re: old sails?
Your sails are probably made from Dracon if they are original. I just sold a 1972 Cal T/2 that had original sails. Dracon sails can last a while if you store them correctly. If the sails are to the point where there is no shape left in them, you can have them rebuilt, Panels replaced, and starched. They will look and act like new for the fraction of the cost.
