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 240 Viper T-Top configuration, with reinforced cutouts that wrap snugly around the T-Top supports, rod holders, and grab rails without sagging or bunching.
Installation takes under five minutes. Drape the cover over the bow, pull it aft past the T-Top frame, secure the adjustable straps beneath the gunwales, and tighten the quick-release buckles. The full elastic hem keeps everything sealed tight.
Absolutely. The reinforced stitching, heavy-duty adjustable straps, and elastic hem system are designed to stay locked down during highway-speed trailering on a tandem-axle trailer without flapping, shifting, or loosening.
Both covers are designed for 24-foot Sea Fox hulls with an 8'6" beam, but the Viper and XT have different deck layouts, console configurations, and hull profiles. Each cover is pattern-cut to its specific model's geometry for a precise fit.
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 your console, fishfinder screens, VHF radio, and all electronics, blocking UV rays, salt spray, bird droppings, and airborne debris.
Our cover fits standard production Sea Fox 240 Viper models with factory T-Top configurations. If your boat has significant aftermarket modifications, contact us before ordering to confirm fitment.
Not at all. Our cover is patterned to the exact exterior dimensions of the 240 Viper hull regardless of weight. The lighter construction actually makes the cover easier to install because the boat sits higher on the trailer, improving access to the straps and buckles.
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 240 Viper is the performance flagship of the 24-foot Sea Fox range. At 24 feet with an 8’6″ beam, 300-horsepower rating, and a 15-degree deadrise hull engineered for speed, the Viper is built for anglers who want to be first to the fishing grounds and last to leave. The lightweight 2,500-pound dry weight and aggressive hull design deliver top-end speeds that leave heavier platforms in the wake. Our Sea Fox 240 Viper T-Top boat cover is precision-cut to this performance hull, wrapping the console, gunwales, and all deck hardware in marine-grade 9oz solution-dyed polyester. Explore our full center console boat cover collection for custom-fit options across every major CC platform.
Performance Hull, Performance Cover
The Viper’s aggressive hull shape, lightweight construction, and performance-oriented deck layout create a unique profile that generic covers cannot accommodate. Our Sea Fox 240 Viper cover is patterned to every detail — reinforced cutouts for the T-Top frame, tailored drapes around the performance-grade leaning post and rod holders, and a full elastic hem cord that cinches tight against the rubrail. One person can install the cover in under five minutes using the adjustable strap-and-buckle system, and it stays locked down at highway speed on a tandem-axle trailer.

Fabric Built for Speed and Salt
Performance boats demand performance protection. Our 9oz solution-dyed polyester is engineered for the punishment that comes with high-speed saltwater fishing — every fiber is saturated with color before weaving for fade resistance that goes all the way through, not a surface coating that breaks down after a season of UV exposure. The breathable weave prevents trapped condensation while the DWR finish repels rain, salt spray, and engine exhaust residue. Whether your 240 Viper stays on a dock lift between tournament runs or rides home on a tandem-axle trailer, this cover delivers uncompromising protection. Need a center console cover for a smaller platform? Check our Sea Fox 21 Bay Fisher center console cover for full-hull CC protection on a dedicated bay boat.
