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
Yes. This is a model-specific cover patterned to the exact hull shape, beam, and deck layout of the 300 OSX. It is not a universal or semi-custom design — it accounts for every contour, from the raised bow platform to the wraparound windshield and aft cockpit.
The cover wraps the hull below the T-Top frame, leaving the hardtop structure exposed. Reinforced patches protect the fabric at every frame contact point. This design provides full deck and cockpit coverage without requiring removal of the T-Top.
Yes. The integrated motor hood is sized for the 300 OSX twin outboard configuration. It covers both engines and cowlings to protect them from UV, rain, and debris during storage or trailering.
Absolutely. The cover includes heavy-duty adjustable trailering straps that secure it at multiple points around the hull. Reinforced stress areas at the bow eye and transom corners prevent fabric failure during highway trailering.
Every cover includes a 7-year warranty on the fabric against UV degradation, mildew growth, and color fade. The warranty covers material defects under normal use and storage conditions.
The cover weighs approximately 45 pounds. It folds into the included free zippered storage bag for compact stowage in the boat’s storage compartments when not in use.
Yes. The standard cover ships in 9oz solution-dyed polyester. We offer a Sunbrella upgrade for owners who want premium-grade marine acrylic with enhanced UV performance and fade resistance.
The cover is designed to sit snug and taut across the deck, minimizing flat spots where water can pool. The adjustable strap system helps maintain proper tension. For boats stored outdoors, a support pole (sold separately) can provide additional crown to shed water.
The pattern includes relief cuts and contoured panels that conform to the raised bow platform and wraparound windshield. These features ensure a smooth, flat lay without bunching or excessive material around complex deck areas.
We stand behind the fit of every cover. If you experience any fitment issues on your 300 OSX, contact our team and we will work with you to resolve it or provide a replacement at no additional cost.
Chaparral 300 OSX T-Top Boat Cover – Flagship Coverage for Chaparral’s Ultimate Day Boat
The Chaparral 300 OSX sits at the top of the OSX outboard sportboat lineup — over thirty-two feet of premium day-boat performance built around a cavernous cockpit, luxury bow lounge, and the kind of offshore-capable hull that eats chop without complaint. Protecting a boat this refined demands more than a generic tarp thrown over the gunwales. Our custom-fitted T-Top cover for the 300 OSX is patterned directly to the hull profile, wrapping below the hardtop frame and shielding the entire deck, cockpit, and helm station from sun damage, rain, pollen, and every other environmental threat that degrades fiberglass, upholstery, and electronics over time.
Tailored to the 300 OSX Hull Profile
At 32’6” LOA and a 9’6” beam, the 300 OSX is a substantial boat with a complex deck layout — raised bow platform, wraparound windshield, dual helm stations, and that expansive aft cockpit with convertible sun lounges. Our pattern accounts for each of these elements, with relief cuts and reinforced patches at every T-Top frame contact point, cleat location, and hardware protrusion. The cover sits flat and snug without bunching, sagging, or water pooling. For protection beyond covers, explore our boat shade kits designed to complement your T-Top setup.
Fabric That Performs in Every Climate
The standard 300 OSX cover ships in 9oz solution-dyed polyester — a fabric engineered to resist UV degradation, mildew, and color fade for a minimum of seven years under warranty. The weave breathes to prevent condensation while remaining waterproof enough to shed rain and dock spray. Double-stitched seams, heavy-duty adjustable trailering straps, and an integrated motor hood for twin outboards round out a cover package built for real-world use, not showroom display. For a comparison in the same OSX family, see our Chaparral 280 OSX T-Top cover.
Built for Chaparral Quality Standards
Chaparral owners expect craftsmanship — it is why the brand has earned nineteen consecutive Customer Satisfaction Awards from the NMMA. We hold our covers to that same standard. Every stitch, strap, and seam is inspected before shipping, and each cover includes a free storage bag for convenient stowage when you are out on the water. Whether you keep the 300 OSX at a marina in the Southeast or trailer it across state lines, this cover protects your investment mile after mile and season after season.
