For those of you who are looking for an affordable boat cover for their CVX-18, check out what I found at Farm and Fleet:
https://www.farmandfleet.com/products/g--18762-classic-accessories-tan-dryguard-waterproof-boat-cover.htmlMade by Classic Accessories, this is the "Tan DryGuard Waterproof Boat Cover" Blain # 635312 and Mfr # 20-085-102401-0.
I ordered it online and picked it up at the store last summer. My boat stays in a barn when its not in the water, so I cannot give a review re: how it handles extreme or prolonged exposure to weather, but it fits great, trailers well and its really easy to put on and take off.
The price is right, too. I paid $132.74 (before taxes) last summer and its online right now for $134.99.
