I used to have a Grady Seafarer that had a helm cover similar to one in this pic. It would easily and quickly snap around top edge of windshield and around and down behind seats to floor, and completely cover helm area. I've been searching for a similar cover for my present offshore model, and have not found any info on them. Is anyone aware of a supplier for these, or is this most likely an item I'll have to get a local canvass person to make?
