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.

Frequently Asked Questions
The cover wraps the entire hull below the hardtop, protecting the center console, helm electronics, live wells, tackle storage, all seating areas, and cockpit surfaces from UV rays, rain, salt spray, and debris. The T-Top frame remains exposed while everything below receives complete coverage.
Choose between 9oz solution-dyed marine fabric with 5 to 7 years of protection, or premium Sunbrella acrylic offering 8 to 10 years of superior fade resistance and durability. Both fabrics are UV-resistant and water-repellent.
Yes. Each cover is patterned specifically for the 400 CC-X's massive catamaran dimensions — 39 feet 8 inches LOA with a 12-foot 8-inch beam — ensuring a precise fit over the wide dual-hull contours without bunching, sagging, or excess material.
The cover uses a hem cord that locks beneath the rubrail combined with heavy-duty adjustable tie-down straps that cinch around the hull. This dual attachment system is engineered for the 400 CC-X's substantial size, keeping the cover secure in strong winds and during extended storage.
The cover protects the hull above the waterline. The quad engines remain uncovered below the transom while the cover provides full protection for the cockpit, console, bow, and all deck surfaces. The reinforced construction is built to handle the stresses of covering a 14,500-pound catamaran.
Every cover includes a 3-year manufacturer's warranty covering defects in materials and workmanship. The warranty applies to both fabric options and all hardware components included with your cover.
Yes. Every World Cat 400 CC-X T-Top cover ships free to your door anywhere in the continental United States, regardless of the cover's large size. No minimum order or hidden shipping fees.
The 400 CC-X has the widest beam in the World Cat lineup due to its catamaran hull design. Our covers are patterned specifically for this exceptional width, providing full coverage across the entire beam without stretching, gaps, or compromise at the gunwales.
Yes. Both fabric options are engineered for extended outdoor exposure. UV-resistant thread prevents sun degradation, the water-repellent finish blocks moisture penetration, and reinforced stitching maintains structural integrity through multiple seasons of continuous marina or dry storage.
The 400 CC-X is the largest center console World Cat produces, featuring a 39-foot 8-inch catamaran hull with quad engines delivering up to 1,200 HP and 604 gallons of fuel capacity. This combination of size, power, and the catamaran platform's inherent stability makes it World Cat's ultimate offshore fishing machine — and its cover must be custom-engineered to match.
World Cat 400 CC-X T-Top Boat Cover
The World Cat 400 CC-X is the flagship of the World Cat fleet — a 39-foot 8-inch catamaran center console powered by quad engines delivering up to 1,200 HP. With a massive 12-foot 8-inch beam, 604 gallons of fuel, and 14,500 pounds of dual-hull construction, the 400 CC-X is built for extended offshore expeditions in conditions that would turn back lesser boats. This custom-fit T-Top boat cover protects the entire hull below the hardtop, shielding the center console, helm electronics, live wells, rod storage, and all cockpit surfaces from UV damage, rain, salt spray, and debris.
Each cover is crafted from your choice of 9oz solution-dyed marine fabric or premium Sunbrella acrylic. Solution-dyed fabric delivers 5 to 7 years of dependable coverage, while Sunbrella acrylic extends protection to 8 to 10 years with superior color retention and fade resistance. Both options feature reinforced double-stitching at every stress point, a hem cord that secures beneath the rubrail, and heavy-duty adjustable tie-down straps engineered for a boat of this size.
Engineered for World Cat’s Largest Catamaran
The 400 CC-X’s nearly 40-foot catamaran hull with a 12-foot 8-inch beam demands a cover built to an entirely different scale than standard boat covers. Our covers are patterned to the 400 CC-X’s exact dimensions, following the twin-hull contours precisely across the widest beam in the World Cat lineup. The T-Top hardtop remains exposed while the cover drapes down to completely protect the expansive cockpit, bow, and gunwale areas without bunching or excess material.
At 14,500 pounds dry weight with a 21-inch draft, the 400 CC-X is an offshore powerhouse. Your cover matches that scale with water-repellent fabric, UV-resistant thread, and construction engineered to withstand years of heavy-duty coastal and offshore exposure without breaking down.
