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.

Contender 31 Open T-Top Boat Cover — Bracket-Mount Bluewater Fortress
The Contender 31 Open is a bracket-mount offshore powerhouse — a 31-foot hull with 24.5-degree deadrise, a 9’8″ beam, and twin outboards pushing up to 700 combined horsepower that make it one of the most capable center consoles in its class. At roughly 7,500 pounds dry, the 31 Open’s hand-laminated biaxial and triaxial fiberglass over structural PVC core delivers the strength-to-weight ratio that has made Contender a legend at every major offshore tournament from the Keys to the Carolinas. The bracket-mount configuration moves the engines aft for maximum cockpit space and improved weight distribution. Protect your investment with a boat shade and T-Top cover for complete year-round protection.
Precision-Fit for the 31 Open’s Bracket-Mount Layout
The 31 Open’s bracket-mounted T-Top and expansive 9’8″ beam create a cover footprint that demands precision patterning. Our cover wraps around the bracket-mount T-Top legs and drapes over the console, leaning post, rocket launcher, and the full cockpit perimeter — shielding every surface from bow to transom. The strap-and-buckle system secures at the rubrail in under five minutes, and the reinforced construction handles any trailering scenario. Oversized fish boxes, flush-mount rod holders, and the full electronics suite are completely protected underneath. For the tournament variant on this same hull, see our Contender 31 Tournament T-Top cover.
Offshore-Proven Fabric Durability
The 31 Open fishes the Gulf Stream, the canyons, and the Bahamas — and between trips it sits exposed to the same punishing subtropical conditions. Our 9oz solution-dyed marine fabric delivers 5–7 years of UV-stable, water-repellent, mildew-resistant protection that keeps the 31 Open’s gelcoat and upholstery in tournament condition. Sunbrella acrylic extends that to 8–10 years for dock-kept boats. Double-stitched seams, hem cord at the rubrail, and a 2-year manufacturer warranty come standard.
