Does your one go over the A frame? Bit hard to tell from the picture on eBay. I know the (unavailable) Duck's Back covers weren't designed to go over an A frame....
The guys from ebay got back to me, largest they do is 6.5m and they dont actually manufacture them, they buy them in from china. Ideally i would like one that covered the A-Frame too..... I'll post a pic of the boat....
