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.
*The warranty periods above are provided by the fabric manufacturer and cover the material itself. For details on what’s included in the warranty for your completed cover, please see our warranty page.

Frequently Asked Questions
The NauticStar 231 Hybrid T-Top cover is available in 9oz solution-dyed marine fabric or premium Sunbrella acrylic. The 9oz option provides 5 to 7 years of UV and weather protection, while Sunbrella extends that to 8 to 10 years. Both are solution-dyed for fade resistance.
Yes. The cover is pattern-cut specifically for the NauticStar 231 Hybrid's factory T-Top with reinforced cutouts around the support legs. The hull is sealed below the hardtop while the white fiberglass T-Top roof stays fully exposed above.
Installation takes under 5 minutes with one person. Drape the cover over the 231 Hybrid's hull, route it around the T-Top legs through the reinforced cutouts, and secure the adjustable strap-and-buckle system beneath the rubrail. No tools required.
Yes. The NauticStar 231 Hybrid cover is reinforced for highway-speed trailering. The hem cord locks tight along the rubrail, and the strap system prevents shifting or flapping. The 231 Hybrid's 13-inch draft makes ramp access easy with the cover on.
Absolutely. The cover creates a complete barrier over the NauticStar 231 Hybrid's cockpit, helm electronics, live well, seating, and all upholstered surfaces. It blocks UV rays, rain, salt spray, bird droppings, pollen, and debris.
Every NauticStar 231 Hybrid T-Top cover includes a 2-year manufacturer warranty covering defects in materials and workmanship. The warranty applies to both fabric options.
The cover is water-resistant with a durable water-repellent (DWR) finish that causes rain and spray to bead off. It is breathable rather than fully waterproof, preventing trapped moisture and mildew from damaging the NauticStar 231 Hybrid's interior.
This cover fits NauticStar 231 Hybrid models from standard production years equipped with the factory T-Top. The Hybrid has maintained a consistent hull design, so if your 231 Hybrid has a factory T-Top, this cover will fit.
The 9oz solution-dyed fabric comes in Navy, Black, and Charcoal. Upgrading to Sunbrella acrylic provides additional color options. All colors are solution-dyed through the fiber for lasting UV and fade resistance.
Shipping is a flat rate per cover for delivery anywhere in the continental United States. Orders typically ship within 1 to 2 business days.
⏱️ Current lead time: 1–3 weeks — every cover is custom-made for your boat.

NauticStar 231 Hybrid T-Top Boat Cover — Bay-to-Offshore Versatility Under One Cover
The NauticStar 231 Hybrid measures 22’9″ with an 8’6″ beam, 2,650-pound dry weight, and runs 250 to 300 horsepower on a fiberglass hull with 13.2 degrees of transom deadrise and a sharp 30.8-degree entry angle — numbers that let it draft 13 inches on the flats while still slicing through offshore chop. NauticStar has been building in Amory, Mississippi since 2002, and the 231 Hybrid is the embodiment of their philosophy: one boat that genuinely bridges bay and offshore fishing without compromising either. The NauticStar Performance System (NPS) — a composite stringer grid with integrated deck support — gives the hull its rigidity and durability. With 79 gallons of fuel and a factory T-Top, the 231 Hybrid is built to work hard. Our custom-fitted T-Top boat covers wrap the entire hull below the hardtop, protecting the cockpit, helm, and every surface from sun, salt, rain, and debris while the white fiberglass T-Top roof remains exposed above.
Tailored to the 231 Hybrid’s Crossover Layout
What makes the 231 Hybrid unique is its dual-purpose deck plan — a shallow-running bay boat hull married to an offshore center console cockpit. Raised bow casting platforms, an aerated live well, lockable rod storage, and a helm station with flip-up bolster seating all share space on a 22’9″ platform that can navigate skinny water one day and run 20 miles offshore the next. Our cover is pattern-cut to wrap around the T-Top support legs, console profile, leaning post, and all gunwale hardware without pulling or sagging. Installation takes under five minutes solo: drape, route, strap, and buckle. The reinforced hem cord locks at the rubrail for a trailer-ready fit that won’t flutter at highway speed. Owners looking at NauticStar’s dedicated coastal platform should check the NauticStar 231 Coastal boat cover for that purpose-built offshore layout.
Protection That Keeps Up with the NPS Hull
NauticStar’s NPS composite stringer system was designed to outlast traditional wood-cored construction, and our cover is built with the same long-view mentality. The 9oz solution-dyed marine fabric delivers 5 to 7 years of UV and weather resistance, while premium Sunbrella acrylic extends that window to 8 to 10 years. Both options are water-repellent, mildew-resistant, and double-stitched at every seam. A 2-year manufacturer warranty covers materials and workmanship on every cover we ship. Anglers who also run bay boats in the same size range may want to look at the Sea Pro 228 Bay boat cover — another well-protected saltwater platform that benefits from the same custom-fit approach.
