new sails for DS1

I have a '67 DS1, #3059, in very nice condition. It seems to have the original O'day sails which look to be almost new. However, I see fluttering in the leech third of the sails in a stiff breeze (13+).
Two questions: Does this mean I need new sails, and, if so, what are the best racing sails for my boat? It has the original one piece mast.
Thanks,
Jeff
