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
Yes — this cover is pattern-cut specifically for the Regulator 31's 31'4" hull and 10'4" beam. The 31 is Regulator's best-selling model and one of their largest center consoles, and this cover wraps the entire hull below the T-Top hardtop, including the deep cockpit, helm station, leaning post, and all seating areas.
The cover is designed for the 31's twin-XTO transom configuration. The fabric wraps aft over the transom and splash well while the massive 450-horsepower engine lower units remain visible below the fabric. The pattern accounts for the wide twin-engine spacing on this flagship hull.
Yes. The Seakeeper Ride system is integrated into the hull and transom below the waterline and deck level — the cover wraps over the deck and doesn't interfere with any Seakeeper components. The system remains fully protected under the cover along with all other deck-level equipment.
Absolutely. The cover fully encloses the helm station, factory Garmin electronics suite, Yamaha digital displays, and all cockpit-level components under a UV-blocking, water-repellent barrier. For a boat with up to 300 gallons of fuel range built for Gulf Stream tournament fishing, protecting that electronics investment is critical.
Two options: 9oz solution-dyed marine fabric (5-7 year lifespan, in Navy, Black, or Charcoal) and premium Sunbrella acrylic (8-10 year lifespan, expanded colors). Both are water-repellent, UV-resistant, and mildew-resistant — essential for a serious offshore platform that demands serious protection.
Yes, though the 31's 10'4" beam makes it the widest Regulator to cover solo. Installation still takes under five minutes — drape from bow to stern, align the T-Top leg cutouts, and secure the strap-and-buckle tie-downs at the rubrail. No tools needed.
Yes — the fiberglass T-Top hardtop roof remains fully visible on top. The cover protects everything below it from bow to transom. T-Top support legs pass through reinforced cutouts. Outriggers, rocket launchers, and spreader lights mounted on the T-Top frame stay above the cover.
Water-resistant with a DWR (durable water repellent) finish. The breathable construction is intentional — it prevents trapped moisture and mildew from degrading gelcoat, upholstery, and electronics underneath. For a boat valued in this range, moisture prevention is more important than waterproofing.
A 2-year manufacturer warranty covers materials and workmanship. The 9oz fabric is rated for 5-7 years and Sunbrella for 8-10 years of useful life under normal marine conditions.
Yes — this cover fits all standard-production Regulator 31 models with a factory T-Top. The 31's Codega hull dimensions and offshore deck layout have remained consistent across production years, though Regulator has added features like the Seakeeper Ride system that don't affect cover fit.
Regulator 31 T-Top Boat Cover — Flagship Offshore Tournament Protection
The Regulator 31 stretches 31’4″ overall with a 10’4″ beam and approximately 11,139 pounds with twin Yamaha XTO 450 engines — one of the most capable offshore center consoles ever built, and Regulator Marine’s best-selling model. Built in Edenton, North Carolina with the signature 24-degree deadrise Codega hull, 300 gallons of fuel, and a top speed approaching 65 mph, the 31 is a legitimate tournament machine that handles Outer Banks inlets, Gulf Stream canyons, and everything in between. A center console curtain complements this T-Top cover perfectly for full helm protection on the dock.
Tournament-Grade Fit for Regulator’s Best-Seller
This cover is pattern-cut for the Regulator 31’s expansive offshore cockpit, twin-450 transom configuration, integrated Seakeeper Ride system, and tournament-grade helm station with factory Garmin electronics. 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 dock or lift storage. Installation takes under five minutes solo. The largest offshore model with a cover available is the Regulator 32 FS T-Top boat cover, built for the classic bluewater workhorse.
Premium Protection for a Premium Investment
The Regulator 31 starts at over $520,000 — the cover protecting it should reflect that investment. Choose 9oz solution-dyed marine fabric for 5-7 years of UV and salt resistance, or step up to premium Sunbrella acrylic for 8-10 years of protection in the harshest offshore environments. Both are water-repellent, mildew-resistant, and breathable to prevent trapped moisture from damaging the 31’s Garmin electronics package, Yamaha digital controls, and premium upholstery. Double-stitched seams and reinforced stress points handle the demands of this large hull. Every cover ships with a 2-year manufacturer warranty within 1-2 business days. For Regulator owners who also run a smaller model, the Regulator 25 T-Top boat cover delivers the same precision for the returned mid-size platform.
