Description

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.

Frequently Asked Questions

The 257 bridges the gap between Grady White's mid-size Fisherman models and the larger Canyon offshore series. At 25'7" with twin outboards and 180 gallons of fuel, the 257 delivers genuine offshore capability in a platform that's still manageable for experienced owner-operators. The 20° deadrise and SeaV² hull construction give it serious rough-water credentials that smaller center consoles can't match.
Yes. With 180 gallons and modern twin four-stroke outboards, the 257 achieves 300+ miles of offshore range at cruise speed. This supports runs to canyon edges 50+ nautical miles offshore with comfortable fuel reserves. For Gulf Stream trolling or mid-range bottom fishing, the 257's fuel capacity is more than adequate.
The 257 accommodates twin outboards up to 250 HP each (500 HP total). Twin Yamaha F150s provide the best balance of efficiency and performance for most owners, while twin F200s deliver stronger acceleration and higher top speed for tournament fishing. The 180-gallon fuel capacity pairs well with modern four-stroke options.
The 20° deadrise provides noticeably better offshore ride quality than the 19° deadrise found on smaller Grady White models. The steeper entry angle cuts through 4–5 foot seas more smoothly, reduces pounding in head seas, and delivers a drier ride at speed. This is a hull designed for serious offshore conditions.
The 257 features a large insulated in-deck fishbox (180+ quarts) with self-draining capability, a 30-gallon transom livewell with recirculating pump, and additional tackle and bait storage compartments. This is tournament-capable fish-handling capacity for a 25-foot center console.
Yes. Perfect Fit's pattern for the 257 accounts for the twin-engine transom layout, wrapping the aft section into a loose, draped pouch that envelops both outboards as a single continuous covering. The pattern accommodates the engine spread and ensures the fabric doesn't bind between the two cowlings or against the transom hardware.
The 257's T-Top features Grady White's signature fiberglass hardtop with aluminum support legs, rod holders, and spreader lights. While smaller than the hardtops on the Canyon 306 or Freedom 325, it provides full helm shade coverage and accommodates electronics. Perfect Fit's cover wraps up to the underside of this hardtop panel, protecting everything below.
Yes. At 4,900 lbs dry weight with an 8'6" beam, the 257 is within standard trailering limits. You'll need a quality tandem-axle trailer and a truck rated for 7,000+ lbs towing capacity. Many 257 owners trailer their boats to different launch ramps for access to various fishing grounds—Perfect Fit's cover protects during highway transport.
The SeaV² hull with 20° deadrise and nearly 5,000-lb displacement handles 4–5 foot seas confidently. The center console layout keeps weight centered for balanced handling, and the 8'6" beam provides solid stability at rest for drift fishing. The deep-V entry channels spray down and away from the cockpit.
Not at all. Perfect Fit maintains custom patterns for every Grady White model regardless of production status. The 257 pattern accounts for the specific T-Top dimensions, console size, hardware positioning, and hull geometry of the 2005–2014 production run. Your cover is manufactured to order with the same quality as current-model covers.

Grady White 257 T-Top Boat Cover

The Grady White 257 is a 25’7″ twin-engine center console that bridges the gap between mid-size fishing boats and full-size canyon runners. Built on the proven SeaV² hull with 20° deadrise, the 257 accommodates twin outboards up to 500 HP total and carries 180 gallons of fuel for 300+ miles of offshore range. The fishing package includes a large insulated in-deck fishbox with self-draining capability, 30-gallon transom livewell with recirculating pump, T-Top hardtop with rod holders and spreader lights, lockable console storage, and a cockpit layout engineered for serious offshore work.

Your 257 deserves a Perfect Fit custom T-Top cover that protects this capable offshore platform. Our cover wraps the full hull below the hardtop, protecting the center console, fishbox insulation, livewell plumbing, helm electronics, cockpit surfaces, and twin-engine assembly from UV exposure, salt spray, and moisture. Solution-dyed marine fabric (5–7 years) or premium Sunbrella acrylic (8–10 years) preserves your boat’s finish, hardware, and upholstery through seasons of offshore fishing or seasonal storage.

Mid-Size Offshore Muscle — Canyon-Capable Center Console

The 257 occupies a sweet spot in Grady White’s center console lineup: large enough for genuine canyon-edge fishing with 180 gallons of fuel and twin-engine reliability, yet manageable enough to trailer between fishing grounds. The 20° deadrise delivers noticeably smoother offshore rides than smaller models, cutting through 4–5 foot seas with the confidence that only a SeaV² hull provides. The insulated fishbox and 30-gallon livewell handle tournament-level catch volumes, and the twin-engine configuration provides the redundancy serious offshore anglers demand.

Engineering & Center Console Precision Fit

Perfect Fit’s cover engineers custom-measure your 257’s T-Top hardtop dimensions, console geometry, fishbox drains, livewell ports, rod holder positions, and 8’6″ beam to create a precision-fit pattern. The reinforced stitching and hem cord secure the cover at the rubrail, while adjustable tie-down straps distribute tension evenly. The aft section extends into a loose, draped pouch that envelops both engines as a single continuous covering without binding between the outboards.
