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.
*The warranty periods above are provided by the fabric manufacturer and cover the material itself. For details on what’s included in the warranty for your completed cover, please see our warranty page.

Frequently Asked Questions
Coastal Explorer. The 321 CE is the largest boat in Grady-White's Coastal Explorer line — a 31'7" center console with a 10'6" beam and twin outboards.
Yes. It's patterned for the 321 CE with its fiberglass T-top: the cover runs up to the underside of the top and wraps the legs, leaving the top, its rod holders and outrigger plates exposed.
No. The Canyon 386 is a much bigger boat — 36'6" with a 13'2" beam and up to three outboards — so it has its own pattern.
Choose 9oz solution-dyed polyester (Navy or Black) for heavy-duty everyday protection, 7oz polyester (Black) for budget-friendly coverage, or premium Sunbrella acrylic (Marine Blue, Black, or Smoke) for maximum UV resistance and longevity.
No. The cover is designed for storage only — on a trailer, lift, dry stack, or at the dock. Towing with it installed can damage the cover and voids the warranty, so take it off before you hit the road.
Materials and workmanship are covered for 1 year, and the fabric carries its own warranty (3 years on 7oz, 5 years on 9oz, and 6 years on Sunbrella). Every cover is made to order, so please allow 1–3 weeks; shipping is a $30 flat rate within the continental US.
Pricing: 7oz $2,560.00 · 9oz $2,775.00 · Sunbrella $3,270.00 — your final total appears below as you build your cover.

Grady-White 321 CE T-Top Boat Cover — Custom-Fit for the Grady-White 321 Coastal Explorer
The Grady-White 321 Coastal Explorer (321 CE) is the largest model in Grady-White’s Coastal Explorer line, which BoatUS described in early 2026 as the line’s new flagship. It has a 31’7″ centerline length (32′ overall), a 10’6″ beam, a 22″ draft and a single 220-gallon aluminum fuel tank, and it is rated for twin outboards up to 700 hp total — typically twin Yamaha F350s. Dealers list its weight without engines at about 8,560–8,760 lb. Standard equipment includes a fiberglass T-top on a painted aluminum frame with four rod holders, LED spreader lights and outrigger plates; a triple-wide helm seat with flip-up bolsters; an aft-facing mezzanine seat with a fold-down Corian counter and tackle storage; a pair of 18-gallon transom livewells; transom seating for four; and a center console with a stand-up head compartment and shower plus forward console lounge seating. This T-Top cover is patterned for the 321 CE with its T-top, and like all of our Grady-White boat covers, it’s cut to this hull rather than a generic 32-foot size chart.
How It Fits the 321 Coastal Explorer
The cover runs up to the underside of the fiberglass T-top and wraps around the frame legs, then drapes forward over the windshield, console and forward lounge to the bow, and aft over the triple helm seat, the mezzanine and the transom seating to the stern, continuing over the twin outboards as one piece. The T-top roof stays exposed. With a 10’6″ beam carried well forward, the 321 CE has a roomy bow, and the pattern is cut to that full shape so the sides stay snug. On a boat this size, installing is easiest with two people: drape it bow to stern, run the hem cord along the rubrail, and cinch the adjustable strap-and-buckle tie-downs. It’s made for storage on a trailer, lift, dry stack, or at the dock — take it off before towing, since trailering with the cover on can damage it and voids the warranty.
Fabric, Warranty & Shipping
Choose 9oz solution-dyed marine fabric for heavy-duty everyday protection (5–7 year service life), a lighter 7oz fabric for budget-friendly coverage, or premium Sunbrella acrylic for 8–10 years of fade resistance. Every option is water-repellent, breathable, mildew-resistant, and double-stitched at the seams. Each cover is backed by our warranty (1 year on materials and workmanship, plus 3–6 years on the fabric) and ships for a $30 flat rate within the US — every cover is made to order, so please allow 1–3 weeks. Compare the Grady-White Canyon 386 T-Top cover for Grady’s bigger offshore center console, or the Grady-White Freedom 225 T-Top cover.
