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 — this cover is pattern-cut specifically for the Key West 239 FS hull with a T-Top. It wraps the 24-foot hull below the hardtop, with fitted cutouts for the T-Top support legs.
No. The cover works with the T-Top in place. The support legs pass through fitted cutouts in the fabric.
Two options: our heavy-duty 9oz solution-dyed polyester (the most popular choice) or premium Sunbrella acrylic canvas (the best for UV resistance and breathability). Both are solution-dyed for permanent colorfastness.
Yes. The cover extends past the transom and fully encloses the outboard engine. No separate engine cover needed — it’s all one continuous piece.
The cover accommodates engines from 200 HP up to the maximum 300 HP rated for the 239 FS. You’ll select your specific motor configuration when ordering.
Yes. The T-Top cover is ideal for lift-stored boats. The adjustable tie-down straps keep the cover secure in wind, and the T-Top frame creates a natural peaked shape that sheds rain.
Yes — the 239 FS is currently in production and is the largest single-engine model in Key West’s Family Sportsman lineup. Our cover fits all model years.
Yes. The cover wraps over the entire hull area below the T-Top, including the full-width bench seat, center console, helm electronics, livewell, fish box, and all seating areas.
The T-Top cover slopes downward from the hardtop frame like a tent, which naturally sheds rain to both sides. The peaked shape prevents pooling better than flat covers.
About 15 minutes with one person. Thread the T-Top legs through the fitted cutouts, drape from bow to stern, cinch the hem cord along the rubrail, and secure the tie-down straps.
Key West 239 FS T-Top Cover — The Big Single-Engine FS, Fully Protected
The Key West 239 FS is the flagship single-engine model in the Family Sportsman lineup — a 24-foot deep-V center console with a 19-degree deadrise, 100-gallon fuel tank, and the largest cockpit in its class. Our custom-fitted T-Top cover wraps the entire hull below the hardtop — the center console, full-width bench seat, gunwales, livewell, fish box, and outboard engine — while leaving the fiberglass T-Top fully exposed above. At 23 feet 9 inches long with an 8-foot-6-inch beam and 2,700 pounds dry, the 239 FS is a serious offshore platform that our cover is pattern-cut to match precisely.
The T-Top’s support legs pass through fitted cutouts in the cover fabric, creating a clean transition between the covered hull and the exposed hardtop. The cover slopes downward from the T-Top frame, draping smoothly to the bow and stern. At the stern, the fabric extends past the transom to fully enclose the outboard engine. A hem cord cinches along the rubrail while the bottom edge reaches nearly to the waterline.
Engineered for the 239 FS’s Deep-V Hull
The 239 FS runs a true 19-degree deadrise — a hull built for punching through offshore chop — and our cover contours to that deep-V shape precisely. Choose our heavy-duty 9oz solution-dyed polyester — the most popular option for its rugged durability and colorfastness — or upgrade to premium Sunbrella acrylic canvas for the best UV resistance and breathability available. Both fabrics are solution-dyed through the entire fiber, so color stays locked in permanently through years of sun, salt, and weather exposure.
Quick One-Person Installation
Installation takes about 15 minutes with one person. Thread the T-Top legs through the fitted cutouts, drape the cover from bow to stern, then secure with the included hem cord and adjustable tie-down straps. The cover stays locked in place on boat lifts, at the dock, and in dry storage.
