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.

Chaparral 21 H2O Boat Cover – Reliable Protection for an Everyday Sport Boat
The Chaparral 21 H2O is designed to do a little bit of everything — ski, tube, cruise, and even drop a line when the mood strikes. It is the Swiss army knife of Chaparral’s entry-level lineup, and owners use these boats hard. That means your cover needs to work just as hard, keeping sun off the upholstery between Saturday outings and shedding rain when afternoon storms roll through. Our custom-fitted cover for the 21 H2O wraps the entire hull in breathable, UV-resistant marine fabric, providing complete protection from bow to stern without the sag, gaps, and pooling problems that plague generic covers.
Built to Match the H2O Layout
The 21 H2O features a versatile open-bow layout with a compact helm, wraparound cockpit seating, and a transom designed for either sterndrive or outboard power. Our cover pattern is cut to the exact hull dimensions of this model — snug along the gunwales, contoured around the windshield, and reinforced at every stress point where hardware, cleats, and the bow eye create contact pressure. The result is a cover that lies flat, stays put, and looks sharp on the trailer or the dock.

Fabric That Works Year-Round
The standard cover ships in 9oz solution-dyed polyester backed by a 7-year warranty against UV damage, mildew, and color fade. The weave breathes to release trapped moisture while remaining water-resistant enough to handle rain, dock spray, and morning dew. Adjustable trailering straps and double-stitched seams come standard on every cover — no cheap snaps or flimsy tie-downs that fail after one season. See the Chaparral 22 cover for the next size up in Chaparral’s entry-level sport boat range.
The Right Cover for the Right Boat
Chaparral built the H2O series as an affordable way to get on the water without sacrificing the quality their brand is known for. Our cover follows that same philosophy — no shortcuts on materials, no compromises on fit, and a price that makes sense for boats in this class. Every cover includes a free storage bag, ships within 1-2 business days, and comes backed by a team that answers the phone when you have questions. For owners who also have a larger Chaparral in the fleet, the Chaparral 300 OSX T-Top cover protects the brand’s flagship sportboat.
