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.

BlackJack 256 T-Top Boat Cover — Big-Water Bay Boat, Full-Deck Defense
The BlackJack 256 measures 25 feet 6 inches overall with an 8-foot 6-inch beam, approximately 2,900 pounds dry weight, and accepts up to 450 horsepower. Built by K2 Marine in Knoxville, Arkansas, the 256 represents the top of the Blackjack lineup — a crossover bay boat that handles open-water runs and backcountry flats with equal confidence. The Kenner family’s 70-plus years of boat-building experience show in the 256’s hand-laid fiberglass hull, 100-percent composite construction with no wood, 80 gallons of fuel, and storage for up to 20 rods across forward sideboxes and under-gunwale racks. A custom-fitted T-Top cover from Perfect Fit wraps the 256’s cockpit in complete protection against sun, salt, and storm damage between fishing days.
Tailored to the 256’s Tournament-Ready Deck
Pattern-cut to the 256’s exact hull dimensions, this T-Top cover wraps the area below the hardtop while leaving the white fiberglass T-Top roof fully exposed. The fit accounts for the 256’s oversized console, leaning post with integrated cooler, rod holders, forward sideboxes, and livewells without excess material or gaps. Installation takes under five minutes — drape, secure the adjustable strap-and-buckle system at the rubrail, and the 256 is covered. The cover handles highway-speed trailering with reinforced seams and tie-downs. For full-enclosure storage protection on the same hull, the BlackJack 256 center console cover wraps the entire cockpit from console to transom.
Protection Built for Saltwater Duty
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. If you run a two-boat fleet, the BlackJack 224 T-Top cover delivers the same craftsmanship on the smaller 23-foot bay platform.
