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
It's patterned for the 210 Montauk Whaler has built since the 2012 model year (21'4", 8'6" beam) with a factory-style T-top. If your boat has a hardtop, a suntop or an aftermarket frame, send us a photo first — the height and leg spacing change where the cover meets the top.
Order the Boston Whaler 210 Montauk Center Console cover. This T-Top pattern is cut to stop at the underside of the top, so on a boat without one it would sag over the console.
No. The 210 Montauk is a larger, newer hull — over two feet longer and wider than the 17-foot classic Montauks — so this cover is cut for it alone. We carry separate patterns for the smaller Montauks.
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 made to protect your boat while it is parked on its trailer, up on a lift or in storage. Take it off before you tow: trailering with the cover on can damage it and voids the warranty.
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 $990.00 · 9oz $1,190.00 · Sunbrella $1,460.00 — your final total appears below as you build your cover.
⏱️ Current lead time: 1–3 weeks — every cover is custom-made for your boat.

Boston Whaler 210 Montauk T-Top Boat Cover — Custom-Fit for the Whaler 210 Montauk With a T-Top (2012–Present)
The Boston Whaler 210 Montauk is the largest boat in Whaler’s classic Montauk line. Whaler announced it in October 2011 as its “largest Montauk yet” and it entered the lineup for the 2012 model year; it has stayed in production since, with dealers still listing new 2024 boats. Per Whaler’s spec sheet it measures 21’4″ overall with an 8’6″ beam and a 15″ draft, weighs 2,650 lb dry without engine, carries 66.5 gallons of fuel, and runs a single outboard of 150 to 200 hp on a 16-degree deadrise reverse-chine hull. The layout is a classic open center console: a bow casting deck with a fiberglass-lidded anchor locker and forward fishbox inside a stainless bow rail, a console with an acrylic windshield and room inside for an optional head, a reversible pilot seat (or an optional leaning post with cooler or 30-gallon livewell), port and starboard aft quarter seats under hinged stern casting platforms, and a swim platform with ladder to port. Whaler offers it with no top, a suntop, a powder-coated T-top or a fiberglass hardtop. This T-Top cover is patterned for the Boston Whaler 210 Montauk with a T-top, and like all of our Boston Whaler boat covers, it’s cut to this hull rather than a generic 21-foot size chart.
How It Fits the 210 Montauk
The cover runs up to the underside of the T-top and wraps around its legs, then drapes forward over the console and windshield, the bow casting deck and bow rail, and aft over the pilot seat or leaning post, the hinged stern casting platforms and the quarter seats, continuing over the outboard as one piece; the T-top canvas or roof stays exposed. Because the Montauk’s gunwales are low and the bow rail runs well aft, the hem sits below the rail line so the bow fishbox and anchor-locker lids stay covered. Installation takes about five minutes: 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 jet 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. If your 210 Montauk has no top, see the Boston Whaler 210 Montauk Center Console cover; for the smaller sister, see the Boston Whaler 190 Montauk T-Top cover.
