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 Bay Sport 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. 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 during storage.
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, casting platforms, and all deck-mounted equipment — from UV rays, rain, salt spray, bird droppings, and debris.
Every Sea Born 21 LX Bay Sport 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 Bay Sport 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 Bay Sport Center Console Boat Cover — Bay-Ready Full Coverage
The Sea Born 21 LX Bay Sport measures 21’1″ with an 8’6″ beam, weighs approximately 2,600 pounds, and runs up to 200 HP with a 68-gallon fuel tank and 13″ draft. Built on the same proven LX hull by Composite Research, Inc. in Blackshear, Georgia, the Bay Sport trim adds a tournament-oriented deck layout to the 21 LX platform — keeping the 18° deadrise stepped hull, no-wood all-composite construction, and 10-year limited hull warranty. A center console boat cover from Perfect Fit wraps the entire boat from bow to stern for complete protection during storage and between fishing trips.
Full Coverage for the Bay Sport’s Tournament Layout
This cover encloses the entire 21 LX Bay Sport — T-Top frame, hardtop, center console, leaning post, and the tournament-style deck with its dedicated casting platforms — in a single piece of pattern-cut fabric. The strap-and-buckle system installs in under five minutes by a single person, and reinforced construction handles highway trailering without concern. The Bay Sport shares the LX21 hull, so if you’re comparing coverage options, the Sea Born 21 FX Bay Sport T-Top cover offers an alternative approach for the FX series bay boat — same stepped hull philosophy, different deck configuration.
Durable Fabric for Year-Round Bay Boat Storage
Bay boats live in some of the harshest conditions — shallow water, salt marshes, and full sun exposure on open flats. 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 at every stress point. Every cover ships with a 2-year manufacturer warranty, adjustable tie-down straps, and a hem cord along the rubrail for a secure fit. The same construction quality protects comparable bay platforms like the Mako 214 CC through every season.
