Premium quality 21ft-23ft (6.4m-7.0m) Jumbo Boat Cover

This Kaiser Boating Jumbo Boat cover is made from 8.1 oz/600d/ 600 denier marine grade polyester. 600d is an indirect measurement of density and weight. The higher the number, the heavier, thicker, and heavier duty. This is the thickest cover you will find. You will see a lot of 300d, even 150d covers, which are proportionally half as thick and 1/4 as thick as our covers.

The fabric we use is coated twice with polyurethane on the bottom or downside, UV protected, and mildew protected.
