Additional information
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 39 Open cover is available in two solution-dyed marine fabrics. The 9oz solution-dyed polyester offers 5 to 7 years of protection and is ideal for lift-kept boats. The Sunbrella marine fabric upgrade provides 8 to 10 years of superior UV resistance for year-round outdoor exposure in bluewater environments.
The Invincible 39 Open cover uses reinforced cutouts that route cleanly around each T-Top support leg and hardtop structure. The custom patterning spans the full 11' beam and 39'2" LOA to deliver a tight, wrinkle-free fit over the entire boat.
Yes. Even at 39'2" in length and 11' of beam, the Invincible 39 Open cover is designed for solo installation in under five minutes. The adjustable strap-and-buckle system secures beneath the rubrail from the dock without climbing aboard.
No — please remove the cover before towing your Invincible 39 Open. Our covers are not designed to be trailered: towing with the cover on can cause severe damage to the cover and voids the warranty. The cover is designed for storage only — on a trailer, boat lift, dry stack, or jet dock — and comes off in minutes at the ramp.
Yes. The Invincible 39 Open cover fully encloses the center console and all helm-mounted electronics, protecting GPS chartplotters, radar displays, fishfinders, and VHF systems from UV, salt spray, moisture, and dust.
Your Invincible 39 Open cover is backed by our manufacturer's warranty for the original purchaser. Materials and workmanship — stitching, straps, buckles, zippers, and other hardware — are covered for 1 year from the purchase date. Fabric is covered for 3 years on 7oz, 5 years on black or navy 9oz, and 6 years on Sunbrella. Covered defects are repaired or replaced after you contact us for a Return Merchandise Authorization (RMA) number. The warranty does not cover improper use, accident or negligence, unauthorized modifications, improper care, mold or mildew, incorrectly placed orders, theft or loss, or acts of God — and traveling with the cover on or using it in the water voids the warranty. See our Warranty page for full details.
Both fabric options for the Invincible 39 Open cover are water-repellent and shed rain quickly without pooling. Breathable fabric construction prevents condensation and mildew from building up on interior upholstery and electronics.
Our cover is patterned for the current production Invincible 39 Open with its deep 24.5° deadrise SVVT hull. If your 39 Open has aftermarket modifications or a non-standard T-Top configuration, contact us with your model year for fitment verification.
The Invincible 39 Open cover is available in 9oz solution-dyed polyester in Navy or Black, 7oz polyester in Black, or premium Sunbrella acrylic in Marine Blue, Black, or Smoke. Choose your fabric and color in the order options above.

Invincible 39 Open T-Top Boat Cover — Bluewater-Grade Protection for the Ultimate Offshore Platform
The Invincible 39 Open is the pinnacle of the monohull lineup — a 39’2″ offshore center console with an 11′ beam, a deep 24.5° deadrise built for bluewater conditions, and enough power capacity (1,400+ HP) to run 550 gallons of fuel to distant fishing grounds and back. Invincible Boats designed the 39 Open on the same Michael Peters SVVT hull platform that made the brand famous, pushing the stepped-vee concept to its largest monohull expression. Covering a boat this capable requires precision patterning, not guesswork. Our custom T-Top cover fits the 39 Open’s exact dimensions and deck layout, protecting every surface from the punishing effects of UV, salt, and tropical storms. Owners who want cockpit protection while underway should also check out our center console curtains for enclosed helm comfort in rough weather.
Tailored to the 39 Open’s Bluewater Command Center
The Invincible 39 Open’s deck is a serious fishing command center: oversized T-Top hardtop with multiple support legs, a center console packed with screens and navigation equipment, a heavy-duty leaning post, transom livewells, coaming pads, rod holders along both gunwales, and enough cockpit space for a full tournament crew. Our cover accounts for every component. Reinforced cutouts wrap each T-Top leg, the fabric spans the full 11′ beam without slack, and the adjustable strap-and-buckle system cinches beneath the rubrail for a snug fit. Remove the cover before towing — it’s designed for storage, not highway travel. Solo installation takes under five minutes from dock level. Whether the 39 Open sits on a lift or on a trailer between tournaments, the cover stays locked in place. Anglers who fish both Invincible and Sea Hunter platforms will find the same hull-specific engineering in our Sea Hunter 35 CC Tournament cover.
Protection That Matches Invincible Quality
A 39-foot offshore hull stored in the Bahamas sun or South Florida salt air needs fabric that refuses to quit. Our 9oz solution-dyed marine fabric delivers 5 to 7 years of dependable UV and weather protection — well suited for lift-kept boats or seasonal tournament schedules. For the 39 Open that stays exposed year-round, our Sunbrella marine fabric upgrade pushes service life to 8 to 10 years with the best color retention and fade resistance available. Both fabrics are water-repellent, mildew-resistant, and breathable to prevent moisture trapping. Double-stitched seams with UV-resistant thread reinforce every stress point, and our warranty (1 year on materials and workmanship, plus 3–6 years on the fabric) comes standard. For another high-performance center console that demands the same caliber of cover, explore our Statement 350 Open cover — a luxury offshore platform that benefits from the same tailored protection.
