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 Ultra 239 SE measures 24 feet 3 inches LOA with an 8-foot 6-inch beam, a deep-V hull with 18-degree deadrise at the transom, and weighs 3,900 pounds dry. Our cover is patterned specifically for these dimensions — the main body drapes from the T-top frame down to enclose approximately 85–90 percent of the hull sides. The fit accounts for the 239 SE's Carolina bow flare, forward console rake, and wider-than-average beam for this length class.
Yes. The Ultra 239 SE is powered by a single Yamaha F300 outboard rated at 300 horsepower. Our cover extends from the bow past the transom and completely encloses the F300 engine cowling, powerhead, lower unit connection point, and transom mounting hardware. This protects the engine from UV degradation that cracks plastic cowlings, salt corrosion on exposed metal components, and water intrusion during storage.
The cover features a separate zippered section that fits around the T-top support legs. The T-top roof remains fully exposed on top — only the underside edges of the frame serve as the primary attachment points. This design lets you install or remove the cover without fighting the hardtop structure, and the zippered section eliminates the baggy, wind-catching fit common with one-piece covers forced over T-top frames.
Yes. The Ultra 239 SE typically comes equipped with a Garmin GPSMAP touchscreen display, VHF radio, and additional helm electronics. Our cover provides complete coverage over the helm station, shielding all screens and electronics from direct UV exposure that cracks displays, fades LCD panels, and degrades waterproof gasket seals over time. This is especially important for the premium electronics package that comes standard on Ultra-series boats.
The Ultra 239 SE is part of Sea Hunt's premium Ultra series, which features upgraded hull geometry, a larger T-top frame with different mounting points, and elevated fit and finish compared to standard Sea Hunt models. Our cover is patterned specifically for the 239 SE's unique dimensions — the T-top leg spacing, console position, gunwale height, and Yamaha F300 cowling profile are all different from other Sea Hunt models. A generic cover cannot account for these differences and will leave gaps, pool water, or flap in the wind.
Absolutely. The 239 SE's 96-gallon fuel tank and 14-inch draft make it ideal for intracoastal and coastal marina use where salt exposure is constant. Our Sunbrella marine-grade fabric is specifically engineered for saltwater environments — it resists salt crystallization, blocks intensified UV rays reflected off the water surface, and prevents mold and mildew growth in the humid conditions typical of coastal storage. The reinforced stainless steel snaps resist corrosion from salt air.
The cover is designed to stay secure during trailering. Adjustable tie-down straps run beneath the hull and cinch tight along the gunwales, preventing wind lift at highway speeds. Reinforced stitching at every stress point handles the vibration and wind load of extended highway travel. The cover fits flush against the hull rather than ballooning out, which reduces drag and prevents the flapping that destroys covers during transport. Many 239 SE owners trailer between fishing tournaments and report the cover holding firm at sustained highway speeds.
A T-top mooring cover is engineered specifically for boats with a fixed T-top hardtop frame. Unlike a full snap-on cover that requires removing the T-top or a loose-fitting universal tarp, a T-top mooring cover uses the hardtop frame itself as the primary structural support. The cover attaches to the underside edges of the T-top, drapes down to cover the cockpit, console, and gunwales, and includes a separate section for the T-top legs. The hardtop roof stays exposed on top. This design provides secure, wind-resistant coverage without the sagging and pooling problems of generic alternatives.
We offer three fabric tiers. The 7 oz polyester is our entry-level option with a 3-year warranty, shipping in black. The 9 oz polyester is our most popular choice among Sea Hunt owners — the heavier weave provides superior abrasion resistance and UV blocking with a 5-year warranty, available in navy or black. Our premium Sunbrella option uses 100% solution-dyed acrylic trusted by marine professionals worldwide, carrying a 6-year manufacturer fabric warranty in black, smoke, or marine blue. All polyester options are solution-dyed so pigment cannot transfer to your gelcoat.
Select your model year, storage method (trailer, lift, dry stack, or dock), T-top type (hardtop, hardtop with aft support bars, or canvas top), engine configuration, and any aftermarket accessories like jack plates or Power Poles. Our design team uses these details along with the 239 SE's factory specifications to pattern your cover for an exact fit. If you have aftermarket modifications that affect the cover profile, note them in the order comments and our team will adjust the pattern accordingly.
Sea Hunt Ultra 239 SE T-Top Boat Cover – Premium Protection for Your Ultra Series
Your Sea Hunt Ultra 239 SE represents the premium end of the Sea Hunt lineup — protect it with a T-top mooring cover engineered to match. At 24 feet 3 inches long with an 8-foot 6-inch beam, the 239 SE packs a deep-V hull with 18-degree deadrise and the signature Carolina bow flare into a nimble package powered by a single Yamaha F300 outboard. Our cover is custom-patterned for the Ultra 239 SE T-top frame, providing complete bow-to-stern coverage while the T-top roof stays fully exposed above.
Why the Ultra 239 SE Deserves a Purpose-Built Cover
The Ultra series features upgraded fit and finish throughout — premium upholstery, integrated Garmin electronics packages, and refined hull design. At 3,900 pounds dry weight with a 96-gallon fuel tank and just 14 inches of draft, the 239 SE can reach skinny backwater flats and still handle open-water chop with confidence. Our Sunbrella marine-grade fabric blocks UV rays that fade premium gelcoat and crack high-end vinyl seating — the same concerns owners of the Sea Hunt 235 Ultra SE face with their Ultra-series investment. A generic cover cannot account for the 239 SE’s specific T-top geometry, forward console rake, or Yamaha F300 cowling profile.
How Our Custom T-Top Cover Fits the 239 SE
The cover attaches directly to the underside edges of the factory T-top frame, then drapes down to enclose approximately 85–90 percent of the hull sides while fully covering the outboard engine. A separate zippered section accommodates the T-top structure so you can install and remove the cover without fighting the hardtop. Reinforced stitching at every stress point, stainless steel snaps, and adjustable tie-down straps along the gunwales keep the cover locked down through coastal winds and seasonal storms.
Built for Real Marine Storage Conditions
Whether docked at the intracoastal, stored on a lift, or trailered between tournaments, the 239 SE stays protected from sun, rain, salt spray, and airborne debris. Our 9 oz marine canvas is the most popular choice for Sea Hunt owners who want heavy-duty protection without excessive weight. For boaters who want the absolute best, our Sunbrella option delivers unmatched UV and mold resistance with a 6-year fabric warranty. Owners of similar mid-range Sea Hunt models like the Sea Hunt 232 Triton trust the same construction and materials. Available in navy, black, and charcoal gray — purpose-built for the Ultra 239 SE and nothing else.
