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.

Frequently Asked Questions
The Frontier 21 center console cover is available in 9oz solution-dyed marine fabric or premium Sunbrella. The 9oz fabric delivers 5 to 7 years of UV and weather resistance, while the Sunbrella upgrade provides 8 to 10 years of protection with superior fade resistance. Both fabrics are water-repellent, mildew-resistant, and double-stitched at every seam.
The cover creates a tent-like canopy that peaks at the center console and slopes down evenly over the bow, gunwales, and transom. The outboard engine at the stern is completely enclosed inside the cover. The fabric extends to the rubrail across the full 8'3" beam.
Yes. The Frontier 21 cover is designed for solo installation in under five minutes. Position the cover so it peaks at the console, spread the fabric across the hull, then secure the adjustable strap-and-buckle system. No tools, snaps, or grommets are needed.
Absolutely. At 1,795 lbs dry, the Frontier 21 is a frequent trailer boat, and this cover is reinforced specifically for that use. Heavy-duty stitching and the strap-and-buckle tie-down system keep the fabric locked tight against the hull during highway transport.
Yes. The center console cover fully encloses the Frontier 21 from bow to transom, including the outboard motor. Console-mounted electronics, gauges, rod holders, and all deck hardware are completely protected from UV exposure, salt corrosion, rain, and wind-blown debris.
Every Frontier 21 cover includes a 2-year workmanship warranty covering stitching, seams, and hardware. The cover is constructed with double-stitched seams and UV-resistant thread designed to hold up in marine conditions.
The cover uses a water-repellent finish that causes rain to bead and shed. The fabric is intentionally breathable rather than fully sealed, allowing air circulation beneath the cover to prevent moisture buildup and mildew — which is more damaging to a stored boat than occasional light rain.
Yes. The cover is patterned for the Frontier 21 (model 2104) with standard factory console and deck configuration. Contact us with your model year if your boat has aftermarket console modifications for fitment confirmation.
The Frontier 21 cover is available in solution-dyed colors including Black, Navy, and Charcoal. Solution-dyeing saturates color into the fiber before weaving, producing a fabric that maintains its appearance through years of direct UV exposure.
Shipping is a flat rate per cover with delivery in 1 to 2 business days. The cover ships to your home or marina, ready for immediate installation on arrival.
Frontier 21 Center Console Boat Cover — Lightweight Bay Boat, Heavyweight Protection
The Frontier 21 is a 21’4″ center console built for practical inshore and nearshore fishing without unnecessary complexity. At 1,795 lbs dry with an 8’3″ beam, the Frontier 21 is one of the lighter boats in its class — easy to trailer, quick to launch, and efficient on fuel with its 50-gallon tank and single outboard rated up to 150 HP. Frontier Boats designed this hull as a straightforward fishing tool: clean deck layout, functional rod storage, reliable performance, and the kind of simplicity that keeps maintenance low and time on the water high. Our custom center console cover creates a single tent-like canopy that peaks at the console and slopes down over the bow, gunwales, and transom in all directions, fully enclosing the cockpit, console, and outboard engine. Between trips, this cover keeps sun, salt, rain, and debris from aging the Frontier 21’s gel coat, electronics, and hardware. For on-the-water shade solutions, browse our boat shade kits designed to complement your cover.
Tailored to the Frontier 21’s Clean Fishing Layout
The Frontier 21 cover is patterned to match this model’s center console, forward deck, open cockpit, rod holders, and transom configuration. The cover peaks at the console — the tallest fixed structure on the boat — and drapes evenly down across the 8’3″ beam, enclosing the 150 HP outboard at the stern and reaching the rubrail on all sides. At under 1,800 lbs, the Frontier 21 is a boat that trailers constantly, and this cover is built for it — reinforced stitching at stress points and an adjustable strap-and-buckle system that holds tight at highway speed without corroding snaps or grommets. One person installs the cover in under five minutes. For an even lighter center console platform, take a look at the Xplor X7 center console cover — a poling skiff built for the shallowest water.
Protection That Matches Frontier Practicality
Frontier Boats built the 21 to be a reliable, low-maintenance fishing platform, and the cover should follow the same philosophy — install it once, trust it for years. Our 9oz solution-dyed marine fabric provides 5 to 7 years of consistent UV and weather protection without fading, ideal for boats that trailer to the ramp every weekend. For owners who store the Frontier 21 outdoors between seasons, our Sunbrella marine fabric upgrade extends protection to 8 to 10 years with exceptional color retention even under relentless coastal sun. Both fabrics are water-repellent, mildew-resistant, and breathable to prevent trapped moisture damage. Double-stitched seams with UV-resistant thread and a 2-year workmanship warranty are standard. For a similar mid-size fishing platform, explore the NauticStar 2102 Legacy center console cover — built with the same attention to hull-specific geometry.
