Poly-Flex II Extra Wide Series Styled-to-Fit Boat Cover for 17.5' Jon Style Bass Boats - Grey

*84" Max Beam Width

Better known as “semi-custom” covers, Styled-to-Fit boat covers are our best selling, most popular category of covers and for good reason. Value. Our Styled-to-Fit boat covers are designed to accommodate all popular hull styles and boat configurations. For example, a 21' V-Hull Runabout boat cover will fit a 21' V-Hull Runabout Sea Ray, Bayliner, Four Winns, Stingray, etc. The cover is not “custom” to the specific boat, but a highly fitted cover designed to accommodate the primary characteristics of the boat style. Our Styled-to-Fit boat covers are great for travel*, mooring and storage, and feature:

  • 1/4″ strong & durable shock cord encased into hem for a snug fit
  • Motor covers are sewn into outboard model boat covers. Some designs come with a separate motor cover

*Trailerable boat covers must be properly installed and tied down.

From Pontoon Boats to Tournament Ski Boats, Jon Boats to Center Console Fishing Boats, Carver has a Styled-to-Fit boat cover that’s right for you!
