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 307 DC was the largest and most capable model in Grady White's DC series at 30'7" LOA with a 10'6" beam. It carried 275 gallons of fuel for 400+ miles of offshore range, accommodated twin outboards up to 700 HP total, featured a spacious enclosed head with sink, massive insulated fishboxes, integrated swim platforms, and a cockpit large enough to work fish while passengers relaxed forward. No other DC-generation model matched its combination of size, power, and range.
The 307 DC and Freedom 325 represent different generations of Grady White's flagship dual console thinking. The 307 DC (2010–2017) offered a slightly longer hull but narrower beam than the Freedom 325 (2018–present). The Freedom 325 added the AV2® hardtop with wraparound windshield and updated styling. Perfect Fit manufactures separate custom patterns because the two models have fundamentally different console positioning, hardtop geometry, and transom configurations.
Extremely competitive. The 275-gallon capacity provides 400+ miles of offshore range with twin outboards at cruise speed. This was a major selling point of the 307 DC—it could run multi-day offshore trips 80+ nautical miles out with comfortable fuel reserves, rivaling the range of dedicated sportfishing boats in this size class.
The 10'6" beam exceeds standard highway width limits (8'6"), making the 307 DC non-trailerable without special wide-load permits. Most 307 DC owners keep the boat in a marina slip, on a heavy-duty dock lift, or in covered dry storage. Perfect Fit's cover is essential for protecting the boat in any of these storage scenarios.
The 307 DC accommodates twin outboards up to 350 HP each (700 HP total). Twin Yamaha F300s deliver excellent performance with 50+ mph top speed, while twin F350s provide maximum thrust for rough offshore conditions. The 275-gallon fuel capacity makes either configuration practical for aggressive offshore fishing.
The 307 DC featured one of the most spacious enclosed heads in any dual console of its era—lockable compartment with marine head, holding tank, sink with pressurized freshwater, and adequate headroom for adults. While the Freedom 325 refined the finishes, the 307 DC's head remains fully functional and well-designed. Perfect Fit's cover accounts for head plumbing vents.
The 307 DC provides approximately 70+ square feet of working cockpit space—substantially more than the 285 DC. The 10'6" beam creates a wide-open fishing platform with room for multiple anglers working fish simultaneously, full walk-around access, and ample tackle and bait prep areas. The dual-console layout keeps passengers forward and out of the fishing zone.
Excellent. The robust SeaV² hull construction at this scale means the structural components will outlast multiple sets of engines. Modern twin Yamaha F300 or F350 four-strokes significantly reduce weight, improve fuel efficiency by 25–30%, and run dramatically quieter than older configurations. A repowered 307 DC with updated electronics and a Perfect Fit cover has decades of offshore service remaining.
The 21° deadrise provides exceptional rough-water capability in 5–6 foot seas. At 8,200 lbs dry weight with a 10'6" beam, the 307 DC offers outstanding stability at rest for drift fishing and confident tracking in following seas. The deep-V entry with progressive deadrise delivers the smooth ride Grady White is known for, even at speed in offshore chop.
At this price point and displacement, cover protection represents one of the best investments in preserving your boat's value. The 307 DC's extensive console surfaces, premium upholstery, helm electronics, fishbox insulation, and gel coat are all susceptible to UV degradation. A Perfect Fit cover prevents the cumulative damage that leads to costly repairs on a boat that's increasingly difficult to find replacement parts for.
Grady White 307 DC T-Top Boat Cover
The Grady White 307 DC is the flagship of Grady White’s DC series—a 30’7″ twin-engine dual console that set the standard for what a dual console could accomplish offshore. Produced from 2010 to 2017 before the Freedom series took the mantle, the 307 DC combined serious sportfishing capability with family-grade comfort in a hull that few competitors could match. At 8,200 lbs dry weight with a commanding 10’6″ beam, the 307 DC accommodates twin outboards up to 700 HP total and carries 275 gallons of fuel for 400+ miles of offshore range. The cockpit delivers 70+ square feet of working space, massive insulated fishboxes, livewell, enclosed head with sink, integrated swim platforms, hardtop with spreader lights, and seating for a full offshore crew.
Your 307 DC requires a Perfect Fit custom T-Top cover engineered for the 10’6″ beam and DC-generation hardtop geometry. Our cover wraps the full hull below the hardtop, protecting both consoles, enclosed head plumbing, fishbox insulation, livewell, cockpit surfaces, helm electronics, swim platforms, and twin-engine assembly from UV exposure, salt spray, and moisture accumulation. Solution-dyed marine fabric (5–7 years) or premium Sunbrella acrylic (8–10 years) preserves your flagship DC investment through seasons of continued offshore use or marina storage.
The Largest DC — Flagship Offshore Dual Console
The 307 DC earned its place as the crown jewel of Grady White’s DC lineup through sheer capability: 275 gallons of fuel for multi-day offshore runs, 70+ square feet of cockpit for serious fish-fighting workspace, a 10’6″ beam that delivers rock-solid stability at rest and in beam seas, and the SeaV² hull with 21° deadrise for confident rough-water handling in 5–6 foot seas. The enclosed head with sink and pressurized freshwater provided family amenities that pure center consoles lacked, while the massive fishboxes and livewell proved the 307 DC could compete with dedicated sportfishing boats twice its price.
Engineering & Flagship DC Precision Fit
Perfect Fit’s cover engineers custom-measure your 307 DC’s specific console dimensions, hardtop frame geometry, head plumbing vents, fishbox drains, livewell ports, swim platform hardware, 10’6″ beam, and twin-engine transom layout to create a pattern unique to the largest DC model. 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.
