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 189 FS hull with a T-Top. It wraps the 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. You never need to remove the hardtop.
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 wraps over the entire center console area including the head compartment, helm electronics, gauges, and switches. Everything below the T-Top is fully covered.
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 115 HP up to the maximum 150 HP rated for the 189 FS. You’ll select your specific motor configuration when ordering.
Yes. The 189 FS is a popular trailerable boat, and our T-Top cover is designed to stay secure during towing. It also works on boat lifts, at the dock, and in dry storage.
Yes — the 189 FS is currently in production. Our cover fits all model years.
A mooring cover wraps the entire boat including over the T-Top. A T-Top cover wraps only the hull below the hardtop — the T-Top stays exposed above. If your 189 FS has a T-Top, this cover is the right choice.
About 15 minutes with one person. Thread the T-Top legs through the fitted cutouts, drape from bow to stern, cinch the hem cord, and secure the straps.
Key West 189 FS T-Top Cover — Versatile Family Sportsman, Locked-In Protection
The Key West 189 FS hits the sweet spot in the Family Sportsman lineup — an 18-foot deep-V center console with a 19-degree deadrise that handles offshore chop while staying nimble enough for inshore creeks. Our custom-fitted T-Top cover wraps the entire hull below the hardtop — the center console, gunwales, seating, livewell, and outboard engine — while leaving the fiberglass T-Top fully exposed above. At 18 feet 9 inches long with an 8-foot beam and 1,650 pounds dry, the 189 FS is the kind of boat that does everything well.
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.
Built for the 189 FS’s Deep-V Hull
The 189 FS runs a true 19-degree deadrise — a genuine offshore hull shape — and our cover contours to that deep-V 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.
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, on a trailer, and in dry storage.
