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 Chaser 21 LX cover is available in 9oz solution-dyed marine fabric (5-7 year lifespan) or premium Sunbrella acrylic (8-10 year lifespan). Both fabrics are solution-dyed for fade resistance and engineered for the salt, sun, and humidity the 21 LX encounters in coastal bay fishing.
Yes. This center console cover fully encloses the entire Sea Chaser 21 LX in a single tent-like shape that peaks at the console and slopes smoothly down to the rubrail in all directions. The outboard engine is completely hidden inside the cover with no secondary bumps or gaps.
Installation takes under 5 minutes solo. Drape the cover over the bow, pull it back over the console and engine, then secure using the hem cord at the rubrail and adjustable tie-down straps with quick-release buckles. No tools or extra hands needed.
No — please remove the cover before towing your Sea Chaser 21 LX. 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 full-enclosure design creates a complete barrier over the Sea Chaser 21 LX's helm electronics, GPS, fishfinder, leaning post, rod holders, and all upholstery surfaces. UV rays, rain, salt spray, bird droppings, and debris are all blocked.
Your Sea Chaser 21 LX 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.
The cover is water-resistant with a DWR (durable water repellent) finish that causes rain to bead and roll off. It is also breathable, allowing trapped moisture to escape and preventing mildew buildup underneath — critical for the 21 LX's enclosed bay boat layout.
Yes. This cover is pattern-cut to the Sea Chaser 21 LX's standard production dimensions (20'7" LOA, 103" beam). It fits all model years with the factory center console configuration.
The Sea Chaser 21 LX 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.

Sea Chaser 21 LX Center Console Boat Cover — Bay-Ready Inshore Protection
The Sea Chaser 21 LX measures 20’7″ overall with a 103″ beam and tips the scales at roughly 1,872 pounds dry — a nimble bay boat built by Carolina Skiff LLC in Waycross, Georgia, using the same all-composite, wood-free construction that has made the parent company the best-selling fiberglass boat builder in the United States. Rated for up to 200 horsepower on a 25″ transom and carrying 52 gallons of fuel, the 21 LX is purpose-built for skinny-water pursuits from redfish flats to coastal marshes. A fitted center console curtain pairs perfectly with this full-coverage boat cover, giving you layered protection for the helm electronics and console area when the 21 LX is docked or stored between trips.
Custom-Fitted to the 21 LX’s Lean Bay Boat Profile
This center console cover is pattern-cut specifically for the Sea Chaser 21 LX’s low-freeboard hull and flush deck layout. The cover drapes over the entire vessel in a single smooth tent-like shape — peaking at the center console and sloping evenly down in all directions to the rubrail, with the outboard engine fully enclosed inside the cover. No secondary bumps, no gaps, just one clean silhouette that seals out rain, UV, salt spray, and debris. A hem cord at the rubrail and adjustable tie-down straps secure the cover, and installation takes under five minutes solo — just drape, strap, and buckle. Remove the cover before towing — it’s designed for storage, not highway travel. If you’re also covering a Sea Chaser 23 LX center console boat cover, the same pattern-cut precision applies to every model in the LX Bay Series.
Protection That Matches Carolina Skiff Quality
The 21 LX’s all-fiberglass composite hull is built to last decades, and your cover should hold up just as long. Choose from 9oz solution-dyed marine fabric rated for 5-7 years of UV and weather resistance, or upgrade to premium Sunbrella acrylic for 8-10 years of protection in the harshest coastal environments. Both options are water-repellent, mildew-resistant, and breathable enough to prevent moisture trapping underneath. Double-stitched seams and reinforced stress points handle the wind loading of outdoor storage. Every cover ships with our warranty (1 year on materials and workmanship, plus 3–6 years on the fabric) and ships within 1–3 weeks. Whether you fish the flats behind Hilton Head or run the ICW from Savannah south, your 21 LX stays protected — and if you’re exploring T-Top options for the HFC series, check out the Sea Chaser 22 HFC T-Top boat cover built with the same pattern-cut precision.
