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.

Boston Whaler 320 Vantage T-Top Boat Cover — The Ultimate Dual Console, Fully Protected
The Boston Whaler 320 Vantage measures 33’6″ with a 10’4″ beam and approximately 9,800 pounds dry — the flagship of the Vantage family and one of the most capable dual console boats on the water. Powered by twin outboards up to 700 total horsepower with 285 gallons of fuel, the 320 Vantage delivers the range and power to run tournament circuits, offshore canyons, and distant islands while its 21-degree deadrise provides a soft, dry ride through the roughest conditions. Built on the foam-cored “Unibond” hull that has defined Boston Whaler’s unsinkable legacy since 1958, this boat features a full hardtop with integrated T-Top, a wraparound windshield, an enclosed passenger console with head, premium bow lounging, and a cockpit that rivals many express cruisers. A custom-fitted T-Top cover from Perfect Fit Boat Covers wraps the entire hull below the hardtop, shielding both consoles, the windshield, electronics, and upholstery from UV degradation, salt spray, and seasonal weather. For additional cockpit shade while at anchor, explore the boat shade collection.
Precision-Fit for the Vantage Flagship
Every Perfect Fit T-Top cover is pattern-cut to the 320 Vantage’s specific hull geometry — including the generous 10’4″ beam, dual console footprint, wraparound windshield, and twin-engine transom — with reinforced cutouts that seat cleanly around the T-Top legs without sagging or excess fabric. A sewn-in hem cord traces the rubrail while adjustable tie-down straps lock the cover from gunwale to gunwale. Installation takes one person under ten minutes on a boat this size — drape from the hardtop frame, pull to the rails, strap, buckle, and walk away. The reinforced construction is built to handle the stresses of covering a 33-foot hull. The Vantage family offers this same precision fit at every size — see the Boston Whaler 230 Vantage T-Top cover for the entry point into the lineup.
Marine-Grade Fabric for the Ultimate Crossover
Choose from 9oz solution-dyed marine fabric rated for 5–7 years of hard use, 7oz performance-weight fabric ideal for covered storage, or premium Sunbrella acrylic engineered to last 8–10 years under direct sun. Every option is water-repellent, mildew-resistant, and double-stitched at every seam for long-term durability. The breathable construction prevents trapped moisture and condensation while blocking 99% of UV rays — critical protection for the 320 Vantage’s windshield, high-end dual electronics suites, and premium upholstery. Each cover includes a 2-year manufacturer warranty and free standard shipping to the continental US within 1–2 business days.
