Boat Cover for 17 ft. Bass Boat

I have had several Boat Covers made by Rays Auto Seat Covers. They usually last 3 to 4 years. I had my last one about that old re sewn on the seams because it started leaking, it still leaked. He quaranteed me that a new cover would not leak water. I had a new cover made and paid what I thought was too high priced at the time. $811.88 because he said the Fabric had gone way up. The new Boat Cover for a 17 ft. Bass Boat still leaked and Rays Auto Seat Cover or the Fabric Company Aqualon after testing said it leaked excessively at the seams and neither Rays or the Aqualon Fabric people would make it good. I would not recomend that anyone have a Boat Cover made by Rays Auto Seat Cover. This is the first Boat Cover that I ever had to leak when Brand New. I feel as though I got Ripped Off and taken advantage of. I have them both turned in to The Better Business Bureau of The Permain Basin.
