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
Our Avid 21 Mag center console cover is crafted from 9oz solution-dyed marine fabric as the standard option, engineered for 5-7 years of UV and weather resistance. We also offer a premium Sunbrella acrylic upgrade rated for 8-10 years. All fabrics are solution-dyed for colorfast performance that won’t fade in harsh marine conditions.
Yes. This is a full center console cover that wraps the entire Avid 21 Mag from bow to stern, covering the console, leaning post, TruTaper gunnels, rod lockers, and all deck surfaces. The pattern is cut specifically for the Mag’s fishing-focused layout.
Installation takes under five minutes and can be done solo. Simply drape the cover over the boat from bow to stern, align with the console and leaning post, and secure using the strap-and-buckle system. The hem cord seats into the rubrail channel for a snug, wind-resistant fit.
Absolutely. The cover is reinforced at all stress points and designed for highway-speed trailering. The strap-and-buckle system and hem cord keep the cover secure during transit, protecting your 21 Mag from road debris, bugs, and weather during transport.
Yes. The cover creates a complete barrier over the Avid 21 Mag’s console-mounted electronics, 5-drawer tackle station, leaning post, and rod lockers. The water-repellent, UV-resistant fabric blocks sun damage, rain, bird droppings, and airborne contaminants.
Every Avid 21 Mag center console cover includes a 2-year manufacturer warranty covering defects in materials and workmanship. The solution-dyed fabric is rated for 5-7 years of service life, and the Sunbrella upgrade extends that to 8-10 years.
The cover is water-resistant with a durable water repellent (DWR) finish that causes rain and spray to bead and roll off. It is intentionally breathable rather than fully waterproof, which prevents moisture and mildew buildup underneath — critical for protecting aluminum boats from corrosion.
Yes. This cover is designed to fit the Avid 21 Mag across standard production years with the factory center console configuration. If your boat has significant aftermarket modifications to the console or leaning post, contact us and we can confirm fitment.
The 9oz solution-dyed fabric is available in Navy, Black, and Charcoal. The premium Sunbrella acrylic offers an expanded color palette. Select your preferred color during checkout using the fabric configurator on this page.

Avid 21 Mag Center Console Cover — Purpose-Built Fishing Platform Protection
The Avid 21 Mag is a dedicated fishing machine built on 5052 marine-grade aluminum in Amory, Mississippi. At 1,522 pounds with a ProMaster™ pad hull, 13° transom deadrise, and capacity for up to 200 HP, this center console delivers stability and performance in skinny water and open bays alike. Our custom-fitted center console cover protects the Mag’s TruTaper™ gunnels with Versatrac rail system, the 5-drawer tackle station, and every rod locker and livewell from the elements. Add a center console curtain for helm protection during storage.
Tailored to the Mag’s Pure Fishing Layout
This cover wraps the full 101-inch beam of the 21 Mag, accounting for the free-standing leaning post with flip-down footrest, the dual lockable rod lockers with cushioned liners, the 21-gallon aft livewell, 12-gallon in-console baitwell, and the 100-quart insulated fish box. The in-floor fuel tank keeps the center of gravity low, and our cover pattern follows the Mag’s clean deck lines precisely. Installation takes under five minutes solo, and the reinforced hem cord locks at the rubrail. See our Avid 21 Fusion center console cover if you own the family-crossover model instead.
Corrosion Defense for Aluminum Construction
Choose 9oz solution-dyed marine fabric rated for 5–7 years of UV and weather resistance, or upgrade to premium Sunbrella acrylic for 8–10 years of protection. Both options feature a breathable weave that prevents moisture and mildew buildup against the Mag’s aluminum hull — critical for avoiding galvanic corrosion in saltwater environments. Double-stitched seams and reinforced stress points withstand years of trailering on this 11-inch-draft, ramp-friendly platform. Every cover ships with a 2-year manufacturer warranty and fast, insured shipping. For Avid boats with a T-Top, check out the Avid 21 Magnum T-Top cover for hardtop-compatible protection.
