This is a winter cover for a older boat that needed some extra protection for the winter. Her new owner was very happy with the cover.
Below is a new bimini top with enclosure. The "window"s are made of Makrolon with is a hard coated polycarbonate product. You can see the clarity in these windows. The owner is an avid Bay fisherman and will be able to enjoy the views from his upper deck. Note, the center panel forward, with the zipper opening, is make of Stratoglass 40. As with almost my outside projects, I used Tenera thread here, which is expensive, but will last at least as long as any fabric, says the manufacturer.
