Sails wear out.  It's a fact of life.  You can patch them, repair them, and replace them.

  • Patch
    • Main:  You may want some spreader patches for the main depending on how you trim downwind.
    • Jib: 
    • Spinnaker: Mostly for accidents launching or dousing the spinnaker.  Sail tape does the job.

  • Repair - No advice; in my experience sewing sails back together yourself is not a multi-outing solution.
