I have a Bayliner Classic with a custom canvas and vinyl window cabin surround and bow cover. On a few of my side covers for the cabin, the covers have shrunk to the point where I can not snap them to the boat. There is about 1/2" to 1 inch of shrinkage at some locations on the cover. This is probably due to the sun shrinking the vinyl windows in the cover. Is there a trick to stretching these back out so they fit again? Would soaking them in cold water help them stretch?
