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 210 Montauk T-Top Boat Cover — The Biggest Montauk, Fully Shielded
The Boston Whaler 210 Montauk stretches 21’4″ with an 8’6″ beam and approximately 2,650 pounds dry, powered by a single outboard up to 200 horsepower with 66.5 gallons of fuel. A 16-degree deadrise delivers a smooth, dry ride through coastal chop while the 15-inch draft keeps skinny-water access open for back-bay and ICW exploration. Built on the foam-cored “Unibond” hull that has made Boston Whaler’s unsinkable promise credible for over six decades, the 210 Montauk is the largest boat in the Montauk family — offering an expansive open cockpit with rod holders, a raw-water washdown, a livewell, and enough deck space for serious tournament fishing. A custom-fitted T-Top cover from Perfect Fit Boat Covers wraps the entire hull below the hardtop, shielding the console, electronics, and upholstery from UV damage, salt spray, and seasonal weather. Browse the full lineup of T-Top boat covers to see how Perfect Fit protects every hull type.
Custom-Cut to the 210 Montauk’s Full-Size Layout
Every Perfect Fit T-Top cover is pattern-cut to the 210 Montauk’s specific hull dimensions, 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 five minutes — drape from the hardtop frame, pull to the rails, strap, buckle, and walk away. The reinforced construction handles highway trailering speeds with zero flutter. The Montauk family offers this same precision fit at every size — see the Boston Whaler 17 Montauk T-Top cover for the compact classic end of the lineup.
Marine-Grade Fabric Built for Coastal Durability
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 — essential protection for the 210 Montauk’s electronics and premium gelcoat. Each cover includes a 2-year manufacturer warranty and free standard shipping to the continental US within 1–2 business days. Boston Whaler owners with a smaller hull in the fleet can also explore the Boston Whaler 130 Sport center console cover built with the same marine-grade materials.
