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 270 Dauntless T-Top Boat Cover — Twin-Engine Versatility, Total Coverage
The Boston Whaler 270 Dauntless measures 27’4″ with a 9-foot beam and 4,800 pounds dry — a twin-engine-capable bay boat that pushes the Dauntless family into genuine offshore territory. Rigged with a single 300 or twin 200-horsepower outboards and carrying 152 gallons of fuel, this boat delivers the range to run tournament circuits, canyon edges, and nearshore structure with confidence. An 18-degree deadrise carves through ocean chop while the 17-inch draft still allows access to many inshore and ICW waterways. Built on the foam-cored “Unibond” hull that defines Boston Whaler’s unsinkable legacy, the 270 Dauntless offers an expansive cockpit with premium seating, integrated rod storage, and a full electronics suite. A custom-fitted T-Top cover from Perfect Fit Boat Covers wraps the entire hull below the hardtop, protecting the console, leaning post, electronics, and upholstery from UV degradation, salt spray, and seasonal weather. Browse the full lineup of center console boat covers to see how Perfect Fit protects every hull type.
Engineered to the 270 Dauntless’s Twin-Engine Dimensions
This cover is pattern-cut to the 270 Dauntless’s exact hull profile — including the wider 9-foot beam and twin-engine transom — with reinforced cutouts that wrap cleanly around the T-Top legs without bunching or excess material. A sewn-in hem cord traces the rubrail while adjustable tie-down straps secure the cover from gunwale to gunwale. One person handles the entire installation in under five minutes — drape from the hardtop frame, pull down to the rails, strap, buckle, and walk away. The reinforced construction handles highway trailering speeds with zero flutter, making the 270 Dauntless easy to transport between home port and distant fishing destinations. The largest Dauntless in the family gets the same precision treatment — see the Boston Whaler 280 Dauntless T-Top cover for details.

Each cover includes a 2-year manufacturer warranty and free standard shipping to the continental US within 1–2 business days.
