Avid 21 Magnum T-Top Boat Cover — ProMaster Hull Protection for Serious Anglers

The Avid 21 Magnum packs serious fishing capability into a 21-foot aluminum platform built in Amory, Mississippi. With a ProMaster™ pad hull delivering 13° of deadrise at the transom and 45° at the entry, this 1,522-pound center console handles up to 200 HP while keeping draft at just 11 inches for skinny-water access. Our custom-fitted T-Top cover protects every inch of this purpose-built fishing machine, from the TruTaper™ gunnels with Versatrac rail system to the free-standing leaning post and 5-drawer tackle station. Browse the full Avid boat covers collection to see all available options for your rig.

Pattern-Cut for the Magnum’s Fishing Layout

This cover wraps precisely around the 21 Magnum’s T-Top legs and center console, accounting for the 101-inch beam and 27-inch side height. The pattern accommodates the dual lockable rod lockers with cushioned liners, the 21-gallon aft livewell, the 12-gallon in-console baitwell, and the 100-quart insulated fish box. Installation takes under five minutes solo with the strap-and-buckle system, and the reinforced hem cord seats firmly at the rubrail. The cover trailers securely at highway speed, so you can protect your Avid 21 Mag center console boat cover investment whether stored or in transit.

Marine-Grade Fabric Built for Aluminum Tough

Choose from 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 are water-repellent, mildew-resistant, and breathable to prevent moisture buildup under the cover. Double-stitched seams and reinforced stress points match the Magnum’s rugged 5052 marine-grade aluminum construction. Every cover ships with a 2-year manufacturer warranty and free standard shipping. If you fish from an Avid Fusion, check out the Avid 21 Fusion center console cover for the same quality protection on that platform.
