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.
*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
The cover wraps from the bow to the transom beneath the T-Top hardtop, shielding the sport cabin, helm station, seating, electronics, and the full 8-foot 6-inch catamaran beam. The hardtop roof stays exposed while everything below is protected from UV, rain, bird droppings, and debris.
Yes, this cover is designed to fit the 266 SC with its twin outboard engines installed up to the maximum 400 HP rating. The aft section accommodates both engines while the cover drapes securely over the sport cabin and the full beam of the catamaran hull.
The cover is crafted from solution-dyed marine fabric that resists UV fading, mold, and mildew. This premium material maintains its color and protective qualities through years of sun exposure, salt spray, and seasonal weather — exactly the conditions a 266 SC catamaran encounters offshore.
The cover attaches to the underside of the T-Top hardtop and wraps down around the entire boat. The flat fiberglass hardtop roof remains exposed on top while the fabric protects everything below — the sport cabin, helm, seating, electronics, and the full catamaran deck.
Yes, the cover includes an integrated tie-down system with adjustable straps designed for highway trailering. The snug fit prevents wind billowing at speed, keeping the cover secure across the 266 SC’s wide catamaran beam during transport to and from the water.
With proper care, the solution-dyed marine fabric option lasts 5 to 7 years and the premium Sunbrella acrylic option lasts 8 to 10 years. Both fabrics are engineered for the harsh marine environment that catamaran owners encounter during offshore fishing and cruising.
Absolutely. The solution-dyed marine fabric is engineered for extended outdoor storage. It breathes to prevent moisture buildup while blocking UV rays, rain, tree sap, and bird droppings from reaching the 266 SC’s interior surfaces, upholstery, and electronics.
Every World Cat 266 SC cover ships with a 3-year warranty against material defects and UV degradation. The solution-dyed marine fabric is built to maintain its protective qualities well beyond the warranty period with normal use in saltwater environments.
Start by draping the cover over the T-Top hardtop, then pull it forward over the bow and aft over the transom around the twin engines. Secure the adjustable straps under the catamaran hulls and tighten the quick-release buckles. One person can install it in about ten minutes.
Yes, the solution-dyed marine fabric is breathable by design, allowing air to circulate beneath the cover while repelling water. This prevents the trapped moisture that causes mold and mildew growth on the 266 SC’s upholstery, sport cabin, and interior surfaces.
World Cat 266 SC T-Top Boat Cover
The World Cat 266 SC is a 26-foot 6-inch power catamaran that brings sport cabin versatility to World Cat’s legendary offshore platform. With twin engines up to 400 HP, a 200-gallon fuel tank, and the catamaran stability that handles beam seas with ease, the 266 SC is built for owners who want overnight capability without sacrificing fishing performance. Our custom-fit T-Top boat cover wraps the entire 266 SC — from the catamaran bow to the twin-engine transom — in solution-dyed marine fabric rated for years of coastal exposure.
This cover is pattern-cut for the 266 SC’s sport cabin catamaran profile. The cabin structure, the helm station, the T-Top hardtop frame, and the 8-foot 6-inch catamaran beam all get accounted for in the fit. Reinforced stitching at every stress point handles the tension that comes with covering a wide-beam catamaran, and the trailerable design keeps the cover secure at highway speed. Every cover ships with a free matching storage bag and our 3-year fabric warranty.
Sport Cabin Catamaran, Maximum Protection
The 266 SC’s sport cabin gives World Cat owners a sheltered space below the helm for overnight trips, weather protection, and secure storage. That cabin structure creates unique coverage requirements that a standard center console cover can’t handle. Our pattern wraps around the cabin entry, follows the windshield angles, and accounts for the hardtop overhang — delivering complete protection for the entire boat.
Whether you anchor overnight at a remote island or keep the 266 SC on a lift between weekend runs, this cover protects the gelcoat, cabin interior, electronics, and upholstery from UV damage, salt air, bird strikes, and rain pooling. The breathable fabric prevents moisture buildup while blocking everything that degrades a boat’s finish and interior over time.
