Re: stiffen sails - how often?
As Sabreman said I also have used Sailcare® located in Ford City, PA for the cleaning, repairing and re-resining process and was impressed with the crispy, white sails they returned to me. As said, if the sail is blown out, they remain blown out, only much nicer looking. Its not a process you would want to do annually however, as it is rather expensive. Perhaps every 5 years or so.
