Last year after my used purchase of M 15 #616 I sent my old sails to Dr Judy B and she measured them, she made me a new set of Hyde sails which are just superb. For insurance sake I went ahead and bought a new Potter 15 jib to use as insurance as a storm jib. I had done something similar for my Precision 21 and probably used that storm jib twice if my memory serves me right so the storm jib to me was plan B and nothing else. Got two reef points on the main sail. Judy B knows her stuff and she'd get my vote as the new old kid on the block cutting sails for Monties. New crisp well cut sails make any sailboat hummmm, I won't sail without a good well made suit of canvas..thanks Judy B J Smiley, Another Wrinkle M15 #616 magoo252@comcast.net
