Tumac has the patterns for the Benningtons. Your year I think the pattern is in Pittsburgh. I ordered from Indiana for a 2008. I had a good experience, Keith had a bad experience. You do have to order a good snap installation tool. $100 plus for a 1 time use. It saved me money but a local shop might beat their pricing. I paid around $600+ shipped
+1 for the local canvas shop. I'll probably get one at the end of this season to replace my badly faded cover. Got a price of $900 to $950 installed for a Sunbrella cover.....
I have never used the factory Bennington covers. I have always had Sunbrella covers made at the local canvas shops. I have a mooring cover that also covers the stern (unlike the factory cover), and a winter cover that covers the entire boat down to the rail. I use my factory cover, to cover the trailer when the boat is in the water.
