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 251 Hybrid combines bay fishing shallow-water capability with offshore deep-water range, bridging two fishing styles in one platform. Hybrid design means the boat features both tournament fishing amenities (multiple livewells, rod storage, casting decks) and family cruiser comfort (head cabin, premium seating, extended range). For cover design, this requires engineered coverage for the head cabin exterior, which includes cabin roof panels and vent lines. Standard center console covers don’t account for cabin structures, so 251 Hybrid covers must feature extended forward coverage and reinforced points where the hardtop meets the cabin structure.
The head compartment is an enclosed cabin containing a marine toilet (part of the marine sanitation device system), small sink, and weatherproof access door. The exterior includes the cabin roofline, cabin sides, cabin windows, and a through-hull vent system for air circulation. A quality boat cover keeps the cabin dry by shedding water away from the cabin roof, preventing water pooling that causes mildew and interior odor problems. The cover protects cabin window seals from UV degradation that can cause water leakage during rain, and shields the through-hull vent from salt spray corrosion.
A marine sanitation device (MSD) is a marine toilet system that either holds sewage in a tank (Type I) or treats it biologically (Type II/III). The MSD vent line runs through-hull and terminates near the cabin exterior. When uncovered, the vent line is exposed to saltwater spray, UV rays that degrade plastic piping, and accumulation of salt deposits that clog the vent. A boat cover keeps the vent line shaded and dry, preventing salt buildup and extending the MSD functional lifespan.
Twin-engine configuration adds weight and hardware at the transom—two engine covers, two sets of spark plug access ports, dual exhaust lines, and redundant cooling water outlets. The added hardware and weight increase transom stress, making the cover corner strap reinforcement critical for preventing slippage under wind load. Twin-engine boats also generate higher water spray when running, making transom-mounted electronics and controls even more vulnerable to saltwater misting.
The 251 Hybrid features multiple separate livewell systems distributed across the boat—typically a forward baitwell, main forward livewell, mid-ship working livewell, and sometimes an aft livewell—totaling 60+ gallons of live-bait and catch-storage capacity. Each livewell has an aeration line, overflow drain, and pump inlet that requires shade and protection from UV damage. Without cover protection, aeration pumps fail when sun exposure degrades impeller materials, while UV-damaged hoses crack and lose pressure integrity.
At 25 feet 2 inches, the 251 Hybrid creates greater surface area (roughly 215 sq ft of exposed top surfaces) and extends higher above the water, making it more susceptible to wind loading and billowing. Properly fitted covers for large boats require reinforced grommet spacing every 12-18 inches (not every 24+ inches like smaller covers) to prevent fabric stress concentration. The 251 extended length also demands multiple stress points along the centerline to prevent oil-canning (fabric wrinkling) between support points.
Premium seating on the 251 Hybrid includes high-back bolstered helm chairs, high-back companion seats, and sometimes swivel pedestals with elevated seat heights and adjustable backrests. Premium seating is typically 4-6 inches taller than standard seats and extends further from the boat centerline. A properly fitted cover must drape smoothly over this elevated seating without compressing the seat backs (which causes permanent creasing and foam degradation) and without creating water-pooling depressions above the seats.
Solution-dyed marine fabric is manufactured with pigment added during the fiber production process, making color an integral part of the fiber rather than a surface coating. This delivers 3-5 years longer UV resistance than canvas, superior mildew prevention due to reduced organic material on the surface, and natural water-shedding properties that canvas cannot match without chemical treatment. Solution-dyed fabrics are inherently breathable—they allow moisture vapor to escape while blocking liquid water—preventing the mildew and mold that develop under traditional canvas covers.
NauticGuard 5-Year + Lifetime Hull Warranty typically transfers to the original boat, not to new owners. However, original owner coverage often includes extended benefits. Check your warranty documentation or contact NauticStar directly to confirm transfer provisions. Regardless of warranty transferability, protecting your 251 Hybrid with a quality boat cover extends the hull operational life and helps maintain the conditions under which warranty claims remain valid.
With a larger boat like the 251 Hybrid, implement a quarterly maintenance schedule: clean the cover with fresh water and mild soap every 3 months, inspect all stress points (grommets, straps, seams) monthly for wear, check water drainage paths for debris blockage, and inspect the cabin area where water tends to pool. Pressure wash below 1,500 PSI annually to remove stubborn salt deposits and algae without damaging seams.
⏱️ Current lead time: 1–3 weeks — every cover is custom-made for your boat.
