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
It's patterned for the Key West 186 Sportsman center console (18'10" x 8') with a T-top. It isn't cut for the 186 Bay Reef or the 186 dual console, which use different decks, or for the 189 FS — see our 189 FS T-Top cover for that boat.
Listings use 186 CC and 186 Sportsman for the same center console, and our cover maker lists a separate Key West 186 T-Top cover. If your boat is badged 186 Sportsman or 186 CC Sportsman, order here; if you're not sure, send us your year and a photo and we'll confirm.
Our T-Top style is made for any boat with a hard top: the factory T-top, an aftermarket aluminum T-top, or a T-top frame with a canvas canopy. The cover fits up under the top and around its legs, so the roof stays exposed. The T-top was a factory option, and many 186s were sold with a bimini, so please make sure yours has a T-top before ordering this style.
Check the model on your registration or the builder's plate, and measure the overall length and beam: the published specs give the 186 Sportsman at about 18'10" long with a 8' beam. Key West built several 186 versions, including the Bay Reef and dual console. Send us your model year, length, beam and a photo of your T-top before you order, and we'll confirm the pattern fits.
Choose 9oz solution-dyed polyester (Navy or Black) for heavy-duty everyday protection, 7oz polyester (Black) for budget-friendly coverage, or premium Sunbrella acrylic (Marine Blue, Black, or Smoke) for maximum UV resistance and longevity.
No. The cover is made to protect your boat while it is parked on its trailer, up on a lift or in storage. Take it off before you tow: trailering with the cover on can damage it and voids the warranty.
Materials and workmanship are covered for 1 year, and the fabric carries its own warranty (3 years on 7oz, 5 years on 9oz, and 6 years on Sunbrella). Every cover is made to order, so please allow 1–3 weeks; shipping is a $30 flat rate within the continental US.
Pricing: 7oz $790.00 · 9oz $975.00 · Sunbrella $1,175.00 — your final total appears below as you build your cover.
⏱️ Current lead time: 1–3 weeks — every cover is custom-made for your boat.

Key West 186 Sportsman T-Top Boat Cover — Custom-Fit for the 186 Sportsman Center Console With a T-Top
Key West Boats builds its fiberglass fishing boats in Ridgeville, South Carolina, and the company has been employee-owned through an ESOP since 2002. The 186 Sportsman, also listed as the 186 CC or 186 CC Sportsman, is an 18-foot single-outboard center console with boats on the market from about the 2008 through 2014 model years. Specs give it an 18’10” length and an 8′ beam, a dry weight of about 1,650 lb, a 40-gallon built-in tank, 19 degrees of deadrise at the transom and a 14-inch draft; most of the boats we found carry a single 115 hp four-stroke. Standard gear included a generous bow casting deck, a 72-quart cooler seat with cushion, a flip-flop cooler seat with backrest, removable aft jump seats, a forward fish box, an aerated livewell with high-speed pickup, recessed gunwale rod racks, a tinted windshield with grab rail and a molded swim platform with ladder. A T-top was a factory option, including a deluxe version with a radio box, spreader lights and rocket launchers. This T-Top cover is patterned for the 186 Sportsman with its T-top, and like all of our Key West boat covers, it’s cut to this hull rather than a generic 18-foot size chart.
How It Fits the 186 Sportsman
The cover runs up to the underside of the T-top and wraps its legs, leaving the canopy and any rocket launchers exposed. Below the top it drapes over the console and windshield and the cooler seats, then runs forward over the bow casting deck and falls to the rubrail along the 8′ beam. Aft, it covers the cockpit and jump seat area and closes around the single outboard in one piece. Pull the removable jump seats before covering if you like a flatter fit. Installation takes about five minutes: drape it bow to stern, run the hem cord along the rubrail, and cinch the adjustable strap-and-buckle tie-downs. It’s made for storage on a trailer, lift, dry stack, or jet dock — take it off before towing, since trailering with the cover on can damage it and voids the warranty.
Fabric, Warranty & Shipping
Choose 9oz solution-dyed marine fabric for heavy-duty everyday protection (5–7 year service life), a lighter 7oz fabric for budget-friendly coverage, or premium Sunbrella acrylic for 8–10 years of fade resistance. Every option is water-repellent, breathable, mildew-resistant, and double-stitched at the seams. Each cover is backed by our warranty (1 year on materials and workmanship, plus 3–6 years on the fabric) and ships for a $30 flat rate within the US — every cover is made to order, so please allow 1–3 weeks.
