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
Yes. Our Onslow Bay 37 tournament boat cover is custom-patterned for the factory T-Top structure and standard helm configuration. The cover accommodates the extended beam and cabin roof typical of the 37 Tournament. Any aftermarket T-Top modifications or console changes may require custom fitting; contact our team to verify your specific build.
For a boat of this investment level and size, Sunbrella acrylic is the preferred choice among tournament owners due to its 8–10 year durability and superior fade resistance. If the 37 is trailered frequently or stored permanently outdoors in intense sun, Sunbrella’s longevity justifies the upgrade. The 9oz marine fabric is excellent for indoor storage scenarios.
Absolutely. The Onslow Bay 37 boat cover extends across the full hardtop frame, around the cabin roof and helm station, and down the extended side rails to the rubrail, protecting your engines, electronics, and exterior finish from UV oxidation and salt spray. At 50 lbs, it’s substantial enough to handle the size and complexity of this platform.
Yes. The 37 tournament cover fully encloses the upper engine hatch and transom rim, shielding triple-engine installations from UV damage and saltwater mist. The cover does not extend below the rubrail, allowing any water that enters to drain safely away from the engines.
We do not recommend trailering with the cover installed, as highway wind loads and road spray can stress seams and tie-downs. For trailering, remove the cover or secure it with heavy-duty ratchet straps specifically designed for road transport. Your cover will last longer if you remove it before travel.
Perfect Fit covers are backed by a 2-year manufacturer warranty against defects in materials and workmanship. Damage from accidents, improper storage, tie-down failures, or normal weathering beyond the fabric’s stated lifespan is not covered. Proper maintenance and storage extend your cover’s effective life significantly.

Onslow Bay 37 Tournament T-Top Boat Cover
The Onslow Bay 37 Tournament represents the apex of Brad Knight’s boatbuilding vision: an offshore platform substantial enough to run the toughest Atlantic conditions, yet refined enough to deliver the precision handling and fuel economy that separate tournament winners from the rest of the fleet. At 37’8” with a commanding 10’6” beam, this 11,000-lb vessel accommodates triple engines up to 1,500 HP and carries 540 gallons of fuel, enabling multi-day offshore expeditions to the continental shelf, wrecks 80+ miles out, and Gulf Stream haunts where the biggest king mackerel and wahoo suspend. The signature Onslow Bay 24° deadrise hull design cuts through Atlantic head seas with authority and maintains a dry, controlled ride even in 8- to 12-foot beam swells—the mark of a boat engineered by a second-generation builder who understands what professional tournament anglers demand. Our custom-patterned Onslow Bay 37 tournament T-Top cover delivers comprehensive protection across the full hardtop structure, cabin roof, helm station, and extended side rails, guarding against UV degradation, salt-air oxidation, and weather exposure that can compromise your boat’s finish and systems between competition weeks and seasonal layups.
This premium Onslow Bay 37 boat cover is engineered with reinforced double-stitched seams at every high-stress junction, a marine-grade hem cord cinched along the full rubrail for secure, wrinkle-resistant tension, and stainless steel tie-down straps with strategic attachment points to anchor the cover against wind loads and storage-yard elements. Choose from durable 9oz solution-dyed marine fabric—engineered to resist UV fading for 5–7 years of reliable performance—or select premium Sunbrella acrylic for 8–10 years of superior protection and color retention. Both fabrics are inherently water-repellent, quick-drying, and formulated with mold and mildew resistance to combat the humid, salt-laden environment of Atlantic coastal storage and mooring. At 50 lbs, the 37 tournament cover is substantial enough to handle the beam and complexity of this larger platform while remaining manageable for single-crew on-deck handling and installation.
The Offshore Tournament Standard
If the 33 (T) is the working tournament workhorse, the Onslow Bay 37 is the open-ocean command center. Triple-engine redundancy, electronic sophistication, and walk-around cabin space position the 37 as the platform of choice for teams running the largest red-label offshore tournaments from North Carolina to South Florida. The deep cockpit accommodates multiple anglers in live-bait rotation, the 540-gallon fuel capacity extends range into the blue water, and the triple-engine option delivers the acceleration and cruising efficiency to fish hard all day and still make it home in daylight. The 24° deadrise provides the stability and predictability that tournament teams rely on—no surprises in rough water, just consistent tracking and controlled motion. Your Perfect Fit Onslow Bay 37 tournament boat cover protects this substantial investment from the cumulative damage of UV exposure, salt spray, and saltwater mist, preserving both resale value and the cosmetic integrity that tournament boats demand.
