Description

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 Pro-Line 20 Sport cover is available in 9oz solution-dyed marine polyester, 7oz solution-dyed polyester, and premium Sunbrella acrylic. All fabrics are solution-dyed — color is permanently fused into every fiber during manufacturing — so the 20 Sport’s cover resists fading from years of coastal UV and salt exposure on dock lifts and trailers.
Yes. Pattern-cut with reinforced cutouts that fit precisely around the T-Top support legs. The fabric wraps the 20 Sport’s FIST-constructed 20’6” hull below the hardtop while leaving the white fiberglass roof fully exposed. The pattern accounts for the 20 Sport’s center console, rod holders, livewell, fishbox, and cockpit layout.
Installation takes under 5 minutes solo with no tools. Drape from bow over the console and T-Top legs, then secure with the hem cord at the rubrail and adjustable tie-down straps with quick-release buckles. The 20 Sport’s compact 20’6” length and 8’5” beam make it one of the easiest Pro-Lines to cover single-handed.
Absolutely. The cover is reinforced at all stress points for highway-speed trailering — double-stitched seams, reinforced corners, and heavy-duty attachment points. At 2,600 pounds dry, the 20 Sport is designed to trailer every weekend, and this cover handles repeated trips without loosening or flapping.
Complete barrier over the Pro-Line 20 Sport’s helm electronics, GPS/fishfinder, rod holders, livewell, fishbox, and all seating surfaces. UV rays, rain, salt spray, bird droppings, and pollen are blocked while the breathable fabric prevents moisture and mildew buildup underneath.
Every Pro-Line 20 Sport cover includes a 2-year manufacturer warranty covering defects in materials and workmanship. The 9oz fabric is rated for 5-7 years and Sunbrella acrylic for 8-10 years of continuous coastal exposure.
Water-resistant with a DWR (durable water repellent) finish that causes rain to bead and roll off. The fabric is also breathable — trapped moisture escapes through the weave, preventing mildew on the 20 Sport’s upholstery and electronics in humid coastal storage.
Yes. Pattern-cut to the Pro-Line 20 Sport’s standard production dimensions (20’6” LOA, 8’5” beam) with factory T-Top configuration. Pro-Line’s FIST hull dimensions have remained consistent across the 20 Sport production run.
9oz fabric: Navy, Black, Charcoal. Sunbrella acrylic: expanded color palette. All options are solution-dyed for permanent UV fade resistance that won’t streak or wash out over time.
Flat $30 per cover, continental US. Ships within 1-2 business days in a protective storage bag.

Pro-Line 20 Sport T-Top Boat Cover — FIST-Built Compact Offshore Platform

The Pro-Line 20 Sport measures 20’6” overall with an 8’5” beam and 2,600 pounds dry — the entry point to Pro-Line Boats’ Sport series center console lineup. Founded in 1968 by Dan and Ray Atwood, Pro-Line has over 55 years of saltwater fishing heritage and builds every hull with their proprietary FIST (Fiberglass Integrated Structural Technology) construction that creates lighter, stronger, lower-maintenance boats than traditional layup methods. Now operating out of Chocowinity, North Carolina, Pro-Line designs each hull with fishing as the primary mission — rod holders, livewells, fishboxes, and ample tackle storage come standard, not as afterthoughts. Powered by up to 200 horsepower with 68 gallons of fuel, the 20 Sport handles nearshore reefs, bay fishing, and coastal cruising with the confidence of a hull that’s been refined over five decades of customer feedback. Browse the center console boat covers collection for fitted covers across all center console brands.

Pattern-Cut for the 20 Sport’s Compact Fishing Layout

This cover is cut specifically for the Pro-Line 20 Sport’s FIST-constructed hull, center console helm, and fishing cockpit with its integrated rod holders, livewell, and fishbox configuration. The fabric wraps the hull below the hardtop with reinforced cutouts around the T-Top support legs, while the white fiberglass hardtop roof remains fully exposed on top. A hem cord at the rubrail and adjustable tie-down straps secure the cover for trailering at highway speeds — and at 20’6” and 2,600 pounds, the 20 Sport is built to trailer every weekend. Installation takes under five minutes solo. The next model up is the Pro-Line 220 Sport T-Top boat cover, covering the 22-foot Sport platform.

55 Years of Innovation, Premium Fabric Protection

Pro-Line’s first boat — a 24-foot dual console sold to charter Capt. Sam Pecorino in 1968 — launched a half-century of fishing-focused innovation that lives in every 20 Sport built today. Your cover should match that heritage. Choose 9oz solution-dyed marine fabric for 5-7 years of UV and salt resistance, or premium Sunbrella acrylic for 8-10 years. Both are water-repellent, mildew-resistant, and breathable to prevent trapped moisture from damaging the 20 Sport’s electronics and upholstery. Double-stitched seams handle regular trailering. Every cover ships with a 2-year manufacturer warranty within 1-2 business days. For the Super Sport offshore series, the Pro-Line 24 Super Sport T-Top boat cover covers the enhanced platform with 140 gallons of fuel and 300 HP capability.
