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 306 Canyon was purpose-built for canyon fishing and offshore tournaments. At 30'6" with a 10'2" beam, 300 gallons of fuel for 450+ miles of range, twin outboards up to 700 HP, and the SeaV² hull with 21° deadrise, the 306 was designed to run 80+ nautical miles offshore, fish all day in open-ocean conditions, and return with confidence. The massive fishboxes, tournament-grade livewell, and wide-open center console cockpit made it a serious competitor in the offshore tournament circuit.
With 300 gallons and twin Yamaha 300 HP outboards, the 306 Canyon achieves 450+ miles of range at cruise speed. This supports aggressive multi-day offshore operations—running to distant canyons, fishing the continental shelf break, and exploring deep-water structure that boats with less fuel simply cannot reach on a single tank.
The 306 Canyon features insulated fishboxes totaling 400+ quarts, including a massive center transom fishbox with interior lighting and drainage, plus forward in-deck boxes. Combined with the 40-gallon recirculating livewell with blue interior and the spacious cockpit, the 306 handles tournament-level catch volumes for multi-species offshore fishing.
The 10'2" beam provides exceptional stability at rest and at trolling speeds—essential for drift fishing and fighting large pelagics in open-ocean conditions. However, it exceeds standard highway width limits (8'6"), making the 306 non-trailerable without special permits. Most owners keep the boat in a marina slip, on a heavy-duty dock lift, or in covered dry storage.
The 306 accommodates twin outboards up to 350 HP each (700 HP total). Twin Yamaha F300s are the most popular configuration, providing 50+ mph top speed with strong fuel efficiency at cruise. Twin F350s deliver maximum acceleration and top-end speed for tournament anglers who need to reach distant fishing grounds quickly.
The 326 Canyon adds approximately 2 feet of length, a wider beam, triple-engine capability, and substantially more fuel and fishbox capacity. The 306 is the sweet spot for twin-engine canyon fishing—large enough for serious offshore work while maintaining the simplicity and efficiency of a twin-engine setup. Choose the 306 for experienced canyon anglers; the 326 for maximum offshore capability.
The 21° deadrise provides the smooth, confident ride that canyon fishing demands—cutting through 5–6 foot seas, steep swells near current edges, and confused seas at the continental shelf break with minimal pounding. At 7,800 lbs displacement with a 10'2" beam, the 306 provides the stability serious offshore anglers demand for drift fishing and trolling in open water.
The 306 features a large fiberglass T-Top hardtop with integrated rod holders, spreader lights, radar pod, and antenna mounts. The center console helm station includes a standing-height windshield, flip-up bolster seating, and a dashboard layout designed for twin-engine offshore operation with multiple electronics displays. Perfect Fit's cover wraps below the hardtop, protecting the entire cockpit.
Excellent. The robust SeaV² hull construction at this scale is built to outlast multiple sets of engines. Modern twin Yamaha F300 or F350 four-strokes provide significant weight reduction, 25–30% better fuel efficiency, and dramatically quieter operation. A repowered 306 Canyon with updated electronics and a Perfect Fit cover delivers decades of continued offshore service.
Canyon boats endure the harshest marine conditions—offshore sun exposure, salt spray, and extended storage between trips. The 306's extensive gel coat, premium upholstery, helm electronics, fishbox insulation, and livewell components are all susceptible to UV degradation and salt corrosion. A Perfect Fit cover prevents cumulative damage that leads to costly repairs on a discontinued model where replacement parts become increasingly scarce.

Grady White 306 Canyon T-Top Boat Cover
The Grady White 306 Canyon is a 30’6″ twin-engine center console built for one purpose: serious offshore canyon fishing. At 7,800 lbs dry weight with a 10’2″ beam, the 306 is powered by twin Yamaha 300 or 350 HP outboards (up to 700 HP total) and carries 300 gallons of fuel for 450+ miles of offshore range. The fishing platform is tournament-grade: insulated fishboxes totaling 400+ quarts with interior lighting, 40-gallon recirculating livewell with blue interior, fiberglass T-Top hardtop with rod holders and spreader lights, lockable rod storage, built-in tackle stations, transom door, and a wide-open cockpit with full 360-degree walk-around access for fighting pelagics in open-ocean conditions.
Your 306 Canyon requires a Perfect Fit custom T-Top cover engineered for the 10’2″ beam and large-format center console geometry. 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 canyon-class investment through seasons of offshore tournament fishing or marina storage.
Twin-Engine Canyon Runner — Tournament-Grade Offshore
The 306 Canyon was built for the anglers who run to the canyons and don’t come back until the fishboxes are full. The 300-gallon fuel capacity supports multi-day offshore operations 80+ nautical miles from port, while the SeaV² hull with 21° deadrise handles the unpredictable conditions at the continental shelf break—steep swells, current edges, and open-ocean weather. The 10’2″ beam delivers rock-solid stability for drift fishing and trolling, and the 400+ quarts of insulated fishbox storage with the 40-gallon livewell handle tournament-level catch volumes across multiple species.
Engineering & Canyon-Format Precision Fit
Perfect Fit’s cover engineers custom-measure your 306 Canyon’s large-format T-Top hardtop, center console dimensions, fishbox drains, livewell ports, rod holder positions, radar pod, transom door hardware, 10’2″ beam, and twin-engine transom layout to create a precision-fit pattern. The reinforced stitching and hem cord secure the cover at the rubrail, while heavy-duty adjustable tie-down straps distribute tension evenly across the wide beam. The aft section extends into a loose, draped pouch that envelops both engines as a single continuous covering without binding.
