Additional information
Choose Your Cover Fabric
7 oz. Polyester — Our entry-level marine cover fabric, woven from 100% polyester fiber at a 7 oz. per linear yard weight. This lighter option keeps the cover manageable for solo handling while still delivering reliable protection against sun, rain, and debris. Backed by a 3-year fabric warranty. Ships in Black.
9 oz. Polyester — Step up to our heavy-duty polyester, engineered at 9 oz. per linear yard for boats that face tougher conditions or extended outdoor storage. The denser weave adds an extra layer of defense against abrasion and weather without adding unnecessary bulk. Protected by a 5-year fabric warranty. Ships in Navy or Black.
Sunbrella® — For boaters who want the best, our Sunbrella covers use 100% solution-dyed acrylic — the same fabric trusted by marine professionals worldwide. Naturally resistant to fading, mold, and water damage, Sunbrella holds its color and integrity season after season. Covered by a 6-year fabric warranty. Ships in Black, Smoke, or Marine Blue.
Both polyester options feature solution-dyed construction, where pigment is infused into each fiber during production rather than applied to the surface afterward. This process locks color deep into the material, preventing any dye transfer to your boat’s gel coat or finish. The result is a cover that stays vibrant without bleeding or rubbing off. Our polyester is also designed to breathe — it allows moisture trapped underneath to vent out naturally, reducing the risk of mildew and keeping your boat dry. The fabric holds its form without sagging or stretching over time, stays lightweight enough for one person to handle, and stands up to prolonged UV exposure and harsh marine weather.

Blue Wave 20 SL Center Console Boat Cover — Entry-Level Bay Boat, Premium Protection
The Blue Wave 20 SL measures 19 feet 7 inches overall with an 8-foot beam, approximately 1,550 pounds dry weight, and accepts up to 200 horsepower. As the entry point into Blue Wave’s SL (Sport Lite) lineup, the 20 SL delivers a self-bailing cockpit, 49 gallons of fuel, and just 11 inches of draft — numbers that put skinny-water flats within reach on every tide. Built by the Parks family in Seminole, Oklahoma from 1992 until the brand’s closure in 2023, the 20 SL earned a loyal following among inshore anglers who valued its light weight and shallow access. A custom-fitted center console cover from Perfect Fit Boat Covers wraps the 20 SL’s cockpit in full protection against sun, salt, rain, and debris during storage or between fishing days.
Tailored to the 20 SL’s Compact Bay Boat Layout
Pattern-cut to the 20 SL’s exact hull dimensions, this center console cover accounts for the console, leaning post, rod holders, livewells, and jump seats without excess material. Installation takes under five minutes — drape the cover over the cockpit, secure the adjustable strap-and-buckle system at the rubrail, and the 20 SL is protected. The cover handles highway-speed trailering with reinforced seams and tie-downs, and the 20 SL’s shallow 11-inch draft keeps ramp access quick. For the next step up in Blue Wave’s 20-foot center console options, the 2000 Pure Bay center console cover fits the upgraded variant with the same precision.
Protection That Outlasts the Elements
Choose from 9oz solution-dyed marine fabric rated for 5 to 7 years of weather resistance or premium Sunbrella acrylic engineered for 8 to 10 years. Both options are water-repellent, mildew-resistant, and double-stitched at every seam. A 2-year manufacturer warranty backs the construction. For a serious size upgrade in the Blue Wave family, the 2800 Makaira T-Top cover protects the flagship 27-foot offshore machine with the same quality craftsmanship.
