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 Sea Born 21 LX center console cover is made from 9oz solution-dyed marine fabric — a heavy-duty material that resists UV damage, mildew, and fading for 5-7 years of reliable protection.
Yes. Unlike a T-Top cover that leaves the hardtop exposed, this center console cover wraps the entire boat from bow to stern — including the T-Top frame, hardtop, center console, and all deck equipment — for complete protection.
Installation takes under 5 minutes with no tools required. Drape the cover over the boat from bow to stern, align it with the hull profile, and secure using the adjustable strap-and-buckle system. One person can handle it easily.
Absolutely. The cover is reinforced at all stress points and designed to stay secure at highway speeds. The strap-and-buckle system keeps everything tight during trailering.
A T-Top cover wraps the hull below the hardtop while leaving the T-Top and hardtop exposed for ventilation. A center console cover encloses the entire boat — hull, T-Top, hardtop, and all equipment — for maximum protection during extended storage or harsh weather.
Yes. The full-enclosure design shields every component — electronics, upholstery, T-Top frame, leaning post, and all deck-mounted equipment — from UV rays, rain, salt spray, bird droppings, and debris.
Every Sea Born 21 LX center console cover includes a 2-year manufacturer warranty covering defects in materials and workmanship under normal use.
Yes. This cover fits all standard production years of the Sea Born 21 LX equipped with a factory T-Top. If Sea Born has made significant hull or T-Top design changes to your specific model year, contact us to confirm fitment.
The 9oz solution-dyed fabric is available in Navy, Black, and Charcoal. All colors are solution-dyed for long-lasting fade resistance.
Shipping is a $38 flat rate per cover to anywhere in the continental United States. Orders typically ship within 1-2 business days.
Sea Born 21 LX Center Console Boat Cover — Full-Hull Composite Protection
The Sea Born 21 LX measures 21’1″ with an 8’6″ beam, weighs approximately 2,600 pounds, and handles up to 200 HP with a generous 68-gallon fuel tank and 13″ draft. Built by Composite Research, Inc. in their 190,000-square-foot Blackshear, Georgia facility since 1995, the 21 LX pairs an 18° deadrise stepped hull with no-wood all-composite construction and a 10-year limited hull warranty. A center console boat cover from Perfect Fit wraps the entire hull from bow to stern — including the T-Top and hardtop — for complete protection during storage, dockside, or on the trailer.
Full Coverage for the 21 LX’s Complete Profile
Unlike a T-Top cover that leaves the hardtop exposed, this center console cover encloses the entire boat — T-Top frame, hardtop, center console, leaning post, and every inch of the self-bailing cockpit with its yacht-finished diamond non-skid deck. The cover is pattern-cut to the 21 LX’s specific dimensions and uses an adjustable strap-and-buckle system for quick installation by a single person. Reinforced stress points handle highway trailering without issue. Owners looking for within-brand options will also find a custom cover for the Sea Born 21 LX Bay Sport center console, the bay-configured trim variant built on the same hull.
9oz Protection for Sea Born’s Composite Build
Sea Born’s no-wood composite hull is built to last a decade under warranty — your full cover should hold up alongside it. The 9oz solution-dyed marine fabric delivers 5-7 years of UV and weather resistance with water-repellent, mildew-resistant performance and double-stitched seams throughout. Every cover includes a 2-year manufacturer warranty, adjustable tie-down straps, and a hem cord along the rubrail for a secure, custom fit. Owners of similarly sized center consoles like the NauticStar 211 Angler trust the same construction quality for year-round protection.
