GOOD NEWS. . . . The PICTURE UPLOAD FUNCTION IS WORKING !!! The tech folks at the parent company have been able to remedy the issue. You can upload pictures once again. Thank you for your patience.
I bought mine here on Iboats. Don't forget your forum discount as it adds up!
Mine's made by Carver, and out of Sunbrella fabric specific to my boat. I don't recommend the generic - one size fits most ones as you'll have fabric where you don't want it and no reinforcements where you do.
Other option is to talk to a few local marinas. Mine deal with mobile canvas shops that will come right to the marina and custom make a cover for you. Expect to pay a few more $$$ for the service.
I've had 3 Carvers now and in my opinion they are the best. I second the no-generic idea. However, look up the Carver options. They DO make custom covers for certain models. If your isn't on the list, I'd go to a local canvas shop.
