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 37 Catamaran cover is available in two solution-dyed marine fabrics. The 9oz solution-dyed polyester provides 5 to 7 years of protection for lift-stored or seasonally used boats. The Sunbrella marine fabric upgrade offers 8 to 10 years of superior UV resistance and color retention for full-time outdoor exposure.
The Invincible 37 Catamaran cover is custom-patterned for the full 12' beam — the widest in the Invincible lineup. The fabric wraps both hulls completely, spans the center tunnel without sagging, and uses reinforced cutouts around T-Top support legs to maintain a tight fit across the entire platform.
Yes. Even with the Invincible 37 Catamaran's 12' beam and 37'2" length, the cover is designed for solo installation in under five minutes. The adjustable strap-and-buckle system cinches beneath both hulls from dock level without requiring you to board the boat.
Yes. The Invincible 37 Catamaran cover is built for highway trailering. The strap-and-buckle cinch system holds the fabric tight across the wide catamaran beam, and reinforced T-Top cutouts prevent flutter and fabric stress at speed.
Yes. The Invincible 37 Catamaran cover encloses the full center console and helm station, protecting multi-screen displays, GPS chartplotters, fishfinders, radar, and communication electronics from UV damage, salt corrosion, and moisture.
The Invincible 37 Catamaran cover comes with a 2-year workmanship warranty covering stitching, seams, and all included hardware. Double-stitched construction with UV-resistant thread ensures durability well beyond the warranty period.
Both fabric options for the Invincible 37 Catamaran cover are water-repellent and engineered to shed rain without pooling — especially important on the catamaran's wide, flat deck surfaces. Breathable construction prevents mildew and condensation underneath.
Our cover is patterned for the current production Invincible 37 Catamaran. If your 37 Cat has a non-standard T-Top setup or aftermarket modifications, contact us with your model year and we will verify fitment.
The Invincible 37 Catamaran cover comes in multiple solution-dyed colors including Black, Charcoal, and Navy. The solution-dyeing process embeds pigment deep into the fiber, preventing the fading that surface-dyed fabrics experience under constant UV exposure.
Shipping is a flat rate per cover with 1 to 2 business day delivery. Your Invincible 37 Catamaran cover ships directly to your door or marina, ready for same-day installation.
Invincible 37 Catamaran T-Top Boat Cover — Maximum Coverage for the Widest Beam in the Fleet
At 37’2″ long with a 12′ beam, the Invincible 37 Catamaran is the widest platform in the Invincible lineup — a twin-hull offshore machine rated for up to 1,800 HP with 670 gallons of fuel capacity and a ready-to-fish weight over 20,000 lbs. This is not a boat that fits under a generic cover. Our custom T-Top cover is patterned specifically for the 37 Cat’s massive footprint, wrapping both hulls from bow to transom and accounting for the catamaran tunnel, oversized deck, and every piece of mounted hardware. Built in Opa-locka, Florida, on Michael Peters’ twin-hull design, the 37 Cat represents Invincible’s most ambitious offshore platform — and our cover protects every square foot of it. Owners looking to extend their time on the water between trips should also explore our boat shade kits for additional cockpit comfort.
Tailored to the 37 Cat’s Massive Twin-Hull Footprint
Covering a 12′ beam catamaran requires precision engineering. The Invincible 37 Cat’s deck layout includes a full T-Top hardtop, an expansive center console with multi-screen electronics, a leaning post or tower option, livewells, rod holders running the length of both gunwales, and a cockpit that offers more usable square footage than most 40-foot monohulls. Our cover drapes over the T-Top with reinforced cutouts at each support leg, spans the entire 12′ beam without sagging or water pooling in the tunnel, and cinches beneath both hulls with the adjustable strap-and-buckle system. Solo installation takes under five minutes, and the secure wrap holds firm during trailering. For the next step up in the Invincible Open lineup, our Invincible 39 Open cover provides the same precision fit on the brand’s largest monohull.
Protection That Matches Invincible Quality
With over 20,000 lbs of boat and a 12-foot beam exposed to the elements, fabric selection matters. Our 9oz solution-dyed marine fabric delivers 5 to 7 years of protection from UV, rain, and salt — a dependable choice for lift-stored boats or seasonal coverage on the Gulf Coast. For the 37 Cat living outdoors year-round, our Sunbrella marine fabric upgrade provides 8 to 10 years of service with industry-leading color retention and fade resistance. Both fabrics are water-repellent, mildew-resistant, and breathable to eliminate trapped moisture underneath. Every seam is double-stitched with UV-resistant thread, and a 2-year workmanship warranty covers the entire cover. If you fish both catamaran and monohull tournament platforms, take a look at our Sea Hunter 35 CC Tournament cover — another elite offshore hull that we protect with the same build quality.
