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.
*The warranty periods above are provided by the fabric manufacturer and cover the material itself. For details on what’s included in the warranty for your completed cover, please see our warranty page.

Frequently Asked Questions
We offer three fabric tiers: our standard 9oz marine-grade solution-dyed polyester, a lighter 7oz option, and a premium Sunbrella acrylic upgrade. All three resist UV fading, mildew, and saltwater damage. Select your preferred fabric at checkout.
Yes. Our cover is pattern-cut specifically for the Sea Fox 256 Voyager T-Top configuration, with reinforced cutouts that wrap snugly around the T-Top supports and accommodate the walkaround cabin profile.
Absolutely. The 256 Voyager's raised cabin structure, windshield angle, and cabin entry are all factored into our custom pattern. The cover drapes smoothly over the cabin profile without bunching or leaving gaps.
Installation takes under five minutes. Drape the cover over the bow, pull it aft past the cabin and T-Top frame, secure the adjustable straps beneath the gunwales, and tighten the quick-release buckles.
Yes. The reinforced stitching, heavy-duty adjustable straps, and elastic hem system are designed to stay locked down during highway-speed trailering without flapping, shifting, or loosening.
Every Perfect Fit boat cover includes a multi-year manufacturer warranty covering fabric defects, stitching failure, and premature UV degradation under normal use conditions.
Yes. The tight custom fit creates a complete barrier over the entire boat including the walkaround cabin area. The breathable fabric prevents trapped condensation that could promote mildew growth on cabin upholstery and sleeping surfaces.
Our cover fits standard production Sea Fox 256 Voyager models with factory T-Top configurations. If your boat has significant aftermarket modifications, contact us before ordering to confirm fitment.
Our 9oz fabric features a durable water repellent (DWR) finish that causes rain to bead and roll off. The fabric is breathable to prevent trapped moisture and mildew growth underneath, making it water-resistant rather than fully waterproof.
Rinse the cover with fresh water after each use in saltwater. For deeper cleaning, use a mild soap solution and a soft brush. Allow the cover to air dry completely before storage. Avoid harsh chemicals or machine washing.
The Sea Fox 256 Voyager is the walkaround variant of the 256 platform — a 25-foot offshore cruiser that combines serious fishing capability with the comfort and convenience of an enclosed cabin area. At 25 feet with a 9’3″ beam, 400-horsepower rating, 20-degree deadrise, and a 150-gallon fuel tank, the 256 Voyager carries the same offshore DNA as the standard 256 but adds a walkaround cabin with sleeping accommodations, a portable head, and a sink. At 4,100 pounds dry, the Voyager is a heavier, more feature-rich platform. Our Sea Fox 256 Voyager T-Top boat cover is precision-cut to the exact dimensions of this hull, including the walkaround cabin profile. Explore our full center console boat cover collection for custom-fit options across every popular platform.
Walkaround Profile, Custom-Fit Cover
The 256 Voyager’s walkaround cabin creates a deck profile that’s fundamentally different from a standard center console — the raised cabin structure, windshield, and cabin entry all affect how a cover must drape. Our cover accounts for every detail of the Voyager layout: the pattern follows the cabin roof line and windshield angle, reinforced cutouts wrap around the T-Top legs, and the full elastic hem cord cinches tight against the rubrail. One person can install the cover in under five minutes. For a different hull configuration at this size, see our Sea Fox 257 T-Top cover for the pure center console variant.
Offshore-Ready Fabric Protection
The Voyager’s 150-gallon fuel capacity and enclosed cabin mean this boat sees extended offshore trips where UV intensity, salt exposure, and weather punishment are at their peak. The cabin upholstery, sleeping surfaces, and enclosed electronics represent a premium investment that demands premium protection. Our 9oz solution-dyed polyester is engineered for exactly these conditions — every fiber is saturated with color before weaving, so UV resistance goes all the way through. The breathable weave prevents trapped condensation both over the deck and inside the cabin area. Whether your 256 Voyager stays on a dock lift or rides home on a heavy-duty trailer, this cover delivers lasting protection. Need a center console cover?
