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 Bimini is Grady White's modern take on the family fishing crossover — a 30'6" dual console that delivers serious offshore fishing capability with premium family amenities. The dual console layout creates a protected port-side passenger area with windshield and seating, while the starboard helm provides full instrumentation. The bow area features convertible seating, the cabin includes an enclosed head, and the fishing cockpit maintains tournament-grade equipment.
The dual console design creates a protected passenger area on the port side with a full windshield, comfortable seating, and grab rails. This gives passengers — especially children and non-anglers — a sheltered, comfortable space while the captain and anglers work the cockpit. The bow seating area with convertible cushions adds additional social space for cruising and anchor-outs.
Despite its family-friendly design, the 306 Bimini is a serious fishing platform: rod holders, insulated fishboxes with drainage, recirculating livewell, wide fishing cockpit with walk-around access, transom door, and a hull designed for offshore conditions. The 280-gallon fuel capacity and twin outboards up to 700 HP support offshore fishing trips 50+ miles from port.
The 306 Bimini accommodates twin outboards up to 350 HP each (700 HP total). Twin Yamaha F300s are the most popular configuration, providing excellent performance with 50+ mph top speed and strong fuel efficiency at cruise. The twin-engine setup provides reliability and redundancy for family boating and offshore fishing.
With 280 gallons and twin Yamaha F300s at cruise, the 306 Bimini achieves 400+ miles of range. This supports full-day offshore fishing trips, island-hopping adventures, and extended coastal cruising without fuel planning stress. The Bimini was designed for versatile use — fishing grounds one weekend, sandbar cruising the next.
The 21° deadrise provides a smooth, confident ride in 4–5 foot seas that keeps both anglers and passengers comfortable. At 8,500 lbs displacement, the Bimini has enough mass to handle moderate offshore conditions without the hobby-horsing that lighter dual consoles experience. The SeaV² hull tracks confidently at cruise and provides stability at rest for fishing and swimming.
The 306 Bimini includes an enclosed head compartment accessed from the cockpit — featuring a marine head, sink, and ventilation. While more compact than a full walkaround cabin, it provides essential privacy and convenience for family boating and extended offshore trips. The head compartment also serves as weather shelter and dry storage.
The 306 Bimini's dual console layout, bow seating, windshield profile, and passenger-side console create a unique shape that differs from standard center consoles. Perfect Fit's cover pattern accounts for both console structures, the bow cushion arrangement, windshield angles, and the fishing cockpit to ensure complete protection for all seating areas, electronics, and fishing equipment.
The 306 Canyon is a pure center console designed exclusively for canyon fishing. The 306 Bimini adds a dual console layout, bow seating, and enclosed head for family versatility. Both share the 30'6" SeaV² hull platform, but the Bimini trades maximum cockpit space for family amenities. Choose the Canyon for dedicated offshore fishing; the Bimini for versatile family fishing.
Even new boats begin degrading from UV and salt exposure immediately. The 306 Bimini's extensive bow cushions, dual console upholstery, passenger-side seating, head compartment components, and helm electronics all represent significant replacement costs. A Perfect Fit cover prevents this damage from day one, maintaining the boat's appearance, functionality, and resale value.

Our cover wraps the full hull below the hardtop, protecting both consoles, bow cushions, enclosed head, helm electronics, passenger seating, 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 dual console investment through seasons of family fishing and offshore adventure.
Dual Console Versatility — Fish Hard, Cruise Comfortably
The 306 Bimini was designed for the owner who refuses to compromise. The dual console layout protects passengers from wind and spray while maintaining a full fishing cockpit at the stern. The 280-gallon fuel capacity supports offshore fishing trips 50+ miles from port, the SeaV² hull with 21° deadrise handles open-water conditions at 8,500 lbs displacement, and the enclosed head adds the convenience that family boating demands. Twin outboards up to 700 HP deliver the performance to reach fishing grounds quickly and return comfortably.
Engineering & Dual Console Precision Fit
Perfect Fit’s cover engineers custom-measure your 306 Bimini’s dual console structures, bow cushion arrangement, windshield profiles, head compartment access, fishbox drains, livewell ports, rod holder positions, 10’3″ 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. The aft section extends into a loose, draped pouch that envelops both engine cowlings as a single continuous covering without binding.
