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.

Sea Fox 186 Commander T-Top Boat Cover — Premium Custom Fit
The Sea Fox 186 Commander packs serious offshore capability into an 18-foot 4-inch platform. With a 19-degree deadrise, 8-foot beam, and 150 HP rating, the 186 Commander handles coastal chop with confidence while remaining trailer-friendly for weekend warriors. Our custom-fitted Sea Fox 186 Commander T-Top boat cover protects every inch of this capable hull — from the flared bow to the integrated swim platform. Made from marine-grade 9oz solution-dyed fabric, this cover delivers uncompromising UV protection, rain resistance, and breathability that prevents mildew in humid climates. See our full center console boat cover collection for additional models and brands we cover.
Precision Coverage for the 186 Commander Layout
The 186 Commander’s hardtop T-Top, leaning post with rod holders, and forward console seating all need proper coverage. Our pattern-cut design wraps cleanly around each of these features with reinforced cutouts and no excess pooling material. The adjustable strap system cinches tight under the hull’s rub rail, and quick-release buckles make installation a one-person job that takes just minutes. Moving up to a bigger Sea Fox? The Sea Fox 197 T-Top cover provides identical fit-and-finish quality for the next size in the lineup.
Defend Your Investment Year-Round
A bare boat exposed to the elements loses value fast — gel coat oxidizes, upholstery cracks, and electronics corrode in the salt air. Our 9oz fabric is solution-dyed at the fiber level for fade resistance that outlasts topical coatings, and the DWR finish sheds rain while remaining breathable. Backed by a multi-year warranty, this cover is built for owners who take long-term boat care seriously. Looking for center console coverage instead? Our Sea Fox 180 Viper center console cover delivers the same custom-fit protection for CC hulls.
