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.

Frequently Asked Questions
The Invincible 35 Catamaran cover comes in two solution-dyed marine fabric options. The 9oz solution-dyed polyester lasts 5 to 7 years and is ideal for lift storage or seasonal use. The Sunbrella marine fabric upgrade provides 8 to 10 years of protection with superior UV resistance for year-round outdoor exposure.
The cover is custom-patterned for the Invincible 35 Catamaran's dual-hull configuration and 11'8" beam. It drapes over the T-Top, wraps both hulls without sagging into the center tunnel, and uses reinforced cutouts around each T-Top support leg for a secure fit unique to catamaran geometry.
Yes. Despite the Invincible 35 Catamaran's wide 11'8" beam, the cover is designed for solo installation in under five minutes. The strap-and-buckle system cinches securely beneath the hulls without requiring you to climb aboard.
Yes. The Invincible 35 Catamaran cover is engineered for highway trailering. The adjustable strap-and-buckle cinch system locks the fabric tight across the wide beam and prevents flutter or shifting at speed, even with the catamaran's broader profile.
Yes. The Invincible 35 Catamaran cover completely encloses the center console and helm area, shielding GPS displays, fishfinders, radar arrays, and VHF radios from UV damage, salt corrosion, rain, and airborne debris.
The Invincible 35 Catamaran cover includes a 2-year workmanship warranty that covers stitching, seams, and all hardware. Every cover is double-stitched with UV-resistant thread to ensure long-term durability.
The Invincible 35 Catamaran cover uses water-repellent marine fabric that sheds rain and prevents pooling. The breathable construction allows airflow beneath the cover, preventing trapped moisture and mildew on the catamaran's upholstery and interior surfaces.
Our cover is patterned for the current production Invincible 35 Catamaran. If your 35 Cat has aftermarket T-Top modifications or non-standard hardware, contact us with your model year and configuration for fitment confirmation.
The Invincible 35 Catamaran cover is available in multiple solution-dyed colors including Black, Charcoal, and Navy. Solution-dyeing locks color into the fiber before weaving, so the fabric resists fading even under intense UV exposure.
Shipping is a flat rate per cover with 1 to 2 business day delivery. Your Invincible 35 Catamaran cover ships directly to your address or marina, ready for immediate installation.
Invincible 35 Catamaran T-Top Boat Cover — Twin-Hull Stability Deserves Purpose-Built Protection
The Invincible 35 Catamaran is a 35’10” dual-hull offshore platform engineered for exceptional stability in open water. Built in Opa-locka, Florida, this catamaran stretches 11’8″ at the beam and delivers a fishing deck that dwarfs comparably sized monohulls — all powered by up to 1,200 HP with 550 gallons of fuel capacity. Protecting that much boat requires more than a generic tarp. Our custom-fitted T-Top cover is patterned from the Invincible 35 Cat’s actual dimensions, wrapping both hulls and the massive cockpit area from bow to transom. The cover accounts for the catamaran’s wider-than-average beam and unique tunnel geometry to deliver a drum-tight fit that sheds wind and rain. Explore our full range of center console boat covers to find the same tailored protection for other offshore platforms.
Tailored to the 35 Cat’s Expansive Dual-Hull Platform
A catamaran hull presents unique challenges for cover design. The Invincible 35’s twin-hull configuration means extra beam, a center tunnel, wider gunwale profiles, and deck space that stretches outboard far beyond a typical monohull. Our cover is patterned to drape over the T-Top hardtop, route around each support leg with reinforced cutouts, and extend across the full 11’8″ beam without sagging into the tunnel or pooling water on flat surfaces. The adjustable strap-and-buckle system secures beneath the hulls for a tight wrap that handles highway trailering without flutter. One person can complete installation in under five minutes — no awkward climbing required. Owners who also fish the Invincible lineup will appreciate the same hull-specific patterning on our Invincible 36 Open cover.
Protection That Matches Invincible Quality
The 35 Catamaran’s variable deadrise and wide beam mean significant surface area exposed to sun, salt, and weather. We offer two solution-dyed marine fabric choices to meet that challenge. Our 9oz solution-dyed polyester is rated for 5 to 7 years of faithful UV and moisture protection, a smart choice for boats stored on lifts or used seasonally. For boats that live outdoors year-round in the Florida Keys sun, our Sunbrella marine fabric upgrade extends that lifespan to 8 to 10 years with unmatched color retention. Every seam is double-stitched with UV-resistant thread, the fabric breathes to prevent mildew buildup, and a 2-year workmanship warranty backs the entire cover. If you run a similarly sized offshore platform, take a look at our cover for the Statement 350 Open — another high-performance hull built for serious water.
