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 cover wraps the entire hull below the T-Top hardtop, protecting the center console, helm electronics, leaning post, livewell, fish box, rod holders, and all seating surfaces. The fiberglass T-Top hardtop stays exposed above the cover for ventilation and airflow.
Yes. This cover is custom-patterned to the 218's specific hull dimensions, 8'6" beam, and T-Top frame mounting geometry. Reinforced cutouts around each T-Top support pole create a weather-sealed fit that prevents wind lifting and water intrusion.
The 218 features a 24-degree deadrise at the transom — one of the steepest in its size class. This aggressive entry angle cuts through chop for a dry, comfortable ride in rough conditions. The foam-filled hull construction adds structural rigidity and unsinkable safety.
The 218 carries 100 gallons of fuel — impressive for a 21-foot boat. This gives anglers genuine offshore range with a single 225 HP outboard, making it capable of reaching nearshore reefs and wrecks 15-20 miles out and returning with comfortable reserve.
For year-round outdoor storage in full sun, Sunbrella acrylic provides the longest protection at 8-10 years. For seasonal use or covered-slip storage, the 9oz solution-dyed fabric at 5-7 years offers excellent performance at a more accessible price. Both are breathable and mold resistant.
The 218 and 220 are both 21-foot center consoles, but the 220 is the current-generation model featuring Sailfish's Variable Degree Stepped (VDS) hull technology. The 218 uses a traditional deep-V hull with 24-degree deadrise and slightly different deck layout and rigging.
The cover is cut to the 218's 8'6" beam width for full side-to-side coverage from rubrail to rubrail. The hem cord threads through the rubrail channel for a perimeter seal, and the T-Top frame supports the center to maintain a peaked profile that sheds rain.
While we recommend removing all loose gear before severe weather, the cover provides excellent protection for helm-mounted electronics during strong storms. The hem cord and tie-down strap system is designed to withstand sustained winds, and the T-Top frame prevents water pooling.
Absolutely. The 218 is a 21-foot boat with an 8'6" beam — compact enough for one person to cover easily. The T-Top frame supports the center while you thread the hem cord and cinch straps. Most owners complete the process in 5-7 minutes.
Both options carry manufacturer warranties: 5-7 years for the 9oz solution-dyed fabric and 8-10 years for the Sunbrella acrylic option. The warranties cover material defects, UV degradation, and premature color fading under normal use conditions.
⏱️ Current lead time: 1–3 weeks — every cover is custom-made for your boat.

Sailfish 218 T-Top Boat Cover
The Sailfish 218 is a 21-foot 3-inch center console built around one of the steepest deadrise angles in its class — a 24-degree entry that slices through chop and delivers a remarkably dry, stable ride for a boat this size. Built in Cairo, Georgia with Sailfish’s foam-filled, wood-free hull construction, the 218 pairs that rough-water hull with a single outboard up to 225 HP and 100 gallons of fuel — enough range to run nearshore reefs 15-20 miles offshore with confidence. This custom-fitted T-Top cover wraps the entire hull below the hardtop in 9oz solution-dyed marine fabric or premium Sunbrella acrylic, protecting the console, electronics, and all interior surfaces.
With 100 gallons of fuel in a 21-foot package, the 218 gives inshore and nearshore anglers the kind of range that usually requires a larger boat — and that kind of capability means the 218 earns serious use that takes a toll on exposed surfaces. The 8’6” beam provides a stable fishing platform with room for rod holders, a functional livewell, and a leaning post with tackle storage. The cover matches the 218’s specific hull dimensions and T-Top frame with reinforced double-stitched seams, a hem cord that channels into the rubrail, and adjustable tie-down straps that create a wind-proof fit capable of handling coastal storm conditions.
24-Degree Deadrise: Built for Rough Water
The 218’s steep deadrise is the hull characteristic that sets it apart from the typical 20-foot center console — it’s a hull designed to punch through confused seas and short-period chop without pounding the crew or drenching the cockpit. Sailfish’s foam-filled core construction adds structural rigidity that reinforces the hull’s performance under load, while the wood-free build eliminates the rot risk that plagues boats stored in salt environments. This cover preserves that engineering with solution-dyed fabric rated for 5-7 years or Sunbrella acrylic rated for 8-10 years — keeping the boat’s surfaces in like-new condition between trips.
