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 standard cover uses 9oz solution-dyed marine polyester that delivers 5-7 years of UV and weather protection. We also offer a 7oz option for lighter-duty use and a premium Sunbrella acrylic upgrade rated for 8-10 years of superior durability and color retention.
Yes. The cover is pattern-cut specifically for the 242 Hybrid Bay's factory T-Top frame with reinforced cutouts around each leg. It drapes over the hardtop and secures beneath the gunwales for complete coverage of the console, leaning post, and cockpit area.
Installation takes under five minutes with no tools required. Drape the cover over the T-Top frame, align the reinforced cutouts around the legs, and secure the adjustable strap-and-buckle system beneath the gunwales. One person can complete the entire process.
Yes. The cover is engineered with reinforced stress points and a secure strap-and-buckle system designed to stay tight at highway speeds. Many owners trailer regularly with the cover in place for continuous protection during transport.
Absolutely. The cover creates a complete barrier over the console, helm electronics, leaning post upholstery, and all cockpit surfaces. It blocks UV rays, repels rain, and prevents salt air from corroding sensitive electronics and fading interior materials.
Every cover includes a 2-year manufacturer warranty against defects in materials and workmanship. This covers stitching, fabric integrity, and hardware components under normal use and proper care.
The cover is water-resistant with a durable DWR (durable water repellent) finish that causes rain to bead and roll off. It is intentionally breathable rather than fully waterproof to prevent moisture and mildew buildup underneath the cover.
Yes. The cover fits all standard production model years of the Blackfin 242 Hybrid Bay equipped with the factory T-Top. If your boat has aftermarket modifications that significantly alter the profile, contact us for a fit consultation.

Blackfin 242 T-Top Boat Cover — Versatile Bay-to-Offshore Protection
The Blackfin 242 Hybrid Bay bridges the gap between inshore versatility and offshore capability — 24’5″ of tournament-proven engineering powered by a single 350 HP outboard on a 22-degree deadrise hull. Built in Williston, Florida by a company with over 50 years of sportfishing heritage dating back to 1973 in Fort Pierce, the 242 carries 3,800 pounds of dry weight and 70 gallons of fuel, giving anglers the range to chase cobia on the reefs or work redfish along the mangrove shorelines. Our custom-fitted T-Top boat cover shields every surface from the hardtop frame down through the console, leaning post, and gunwales — blocking UV damage, repelling rain, and guarding against the corrosive salt environment that shortens the life of electronics and gel coat. Browse our full selection of T-Top boat covers to find protection designed for your hull.
Tailored to the 242’s Hybrid Bay Layout
The 242 Hybrid Bay’s open deck plan maximizes fishable space with a layout that transitions seamlessly from shallow bay flats to nearshore structure. Our cover is pattern-cut to the exact 24’5″ by 8’10” profile with reinforced openings around the T-Top legs, tailored contours around the console, leaning post, and rod holders, and stress-reinforced contact points at every cleat and fitting. The adjustable strap-and-buckle system installs solo in under five minutes and stays secure during trailering at highway speed. With a shallow 21″/33″ draft, the 242 handles skinny-water ramps with ease, and the lightweight cover adds no unnecessary bulk to your trailer setup. For Blackfin’s dedicated offshore platform in the same size class, see the Blackfin 252 Center Console cover built for twin-engine capability.
Protection That Matches Blackfin Quality
Blackfin engineers the 242 to handle serious coastal conditions from Florida Bay to the Gulf Stream, and our covers are built with the same no-compromise mindset. Choose from proven 9oz solution-dyed marine fabric — delivering 5-7 years of solid UV and weather protection — or upgrade to premium Sunbrella acrylic for 8-10 years of superior durability and color retention. Both fabrics are water-repellent, mildew-resistant, and quick-drying, with reinforced double-stitched seams at every stress point. Every cover ships with a 2-year manufacturer warranty against defects in materials and workmanship. Need protection for a larger Blackfin?
