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.
*The warranty periods above are provided by the fabric manufacturer and cover the material itself. For details on what’s included in the warranty for your completed cover, please see our warranty page.

Frequently Asked Questions
Yes — this cover is pattern-cut specifically for the Regulator 21 FS's 20'6" hull and 8'2" beam, including the forward-seating bow area ahead of the console. The fabric drapes over the bow seats, center console, and leaning post while fitted cutouts allow the T-Top support legs to pass through cleanly.
Absolutely. The cover wraps the entire hull below the T-Top hardtop, fully enclosing the helm station, Yamaha digital gauges, flush-mount electronics, and all cockpit components. Salt spray, UV, rain, and bird droppings stay off your electronics and upholstery.
Yes. The cover is reinforced with double-stitched seams and a hem cord at the rubrail to handle highway speeds. Many 21 FS owners trailer regularly since it's Regulator's most compact center console at roughly 2,700 pounds dry, and this cover stays secure at highway speed.
Two options: 9oz solution-dyed marine fabric (rated 5-7 years, available in Navy, Black, or Charcoal) and premium Sunbrella acrylic (rated 8-10 years, with an expanded color selection). Both are water-repellent, UV-resistant, and mildew-resistant — built to handle the salt air environment where most Regulators live.
Under five minutes solo. Drape the cover over the hull from bow to stern, align the T-Top leg cutouts, and secure the adjustable strap-and-buckle tie-downs along the rubrail. The 21 FS is the smallest Regulator ever built, so the cover is very manageable for one person.
The white fiberglass T-Top hardtop roof stays fully exposed on top. The cover wraps the hull below the hardtop only — from the bow to the transom, including the cockpit, console, and all seating areas. The T-Top support legs pass through reinforced cutouts in the fabric.
Yes. The cover is designed for the 21 FS's single-engine transom configuration (up to 200 HP). The fabric extends aft to cover the transom area while the engine's lower unit remains visible below the fabric — no separate engine cover or cap needed.
Water-resistant with a DWR (durable water repellent) finish, not fully waterproof. This is intentional — the breathable fabric prevents moisture and mildew from getting trapped underneath the cover, which is critical for boats stored in humid coastal environments like the Outer Banks where many Regulators are docked.
Every cover includes a 2-year manufacturer warranty covering materials and workmanship. The 9oz solution-dyed fabric is rated for 5-7 years of useful life, and Sunbrella acrylic is rated for 8-10 years, so coverage typically extends well beyond the warranty period.
Yes — this cover fits all standard-production Regulator 21 FS models equipped with a factory T-Top. The 21 FS hull and deck layout have remained consistent across model years, so the pattern-cut fit applies regardless of year.
⏱️ Current lead time: 1–3 weeks — every cover is custom-made for your boat.

Regulator 21 FS T-Top Boat Cover — Entry-Level Offshore Excellence
The Regulator 21 FS measures 20’6″ overall with an 8’2″ beam and weighs roughly 2,700 pounds dry — the most compact center console ever built by Regulator Marine in Edenton, North Carolina. Powered by up to 200 horsepower on a single outboard with 100 gallons of fuel, the 21 FS carries the same Lou Codega-designed 24-degree deadrise Sharp Entry hull that made Regulator famous for taming the treacherous Outer Banks inlets. A custom-fitted T-Top boat cover from Perfect Fit keeps this capable offshore platform sealed against salt, UV, and weather whenever she’s resting on the lift between trips.
Tailored to the 21 FS’s Compact Forward-Seating Layout
This cover is pattern-cut specifically for the Regulator 21 FS’s forward-seating bow configuration and center console helm station. The fabric wraps the hull below the hardtop with reinforced cutouts around the T-Top 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 installation takes under five minutes solo — just drape, strap, and buckle. If you’re also covering a classic Regulator 23, the Regulator 23 (1990-2012) T-Top boat cover uses the same pattern-cut precision for that legendary hull.
Protection That Matches Regulator Build Quality
Regulator Marine has been building premium center consoles since 1988 — hand-laid fiberglass with vinylester resin barriers and composite coring that sets the standard for offshore durability. Your cover should match that commitment. Choose 9oz solution-dyed marine fabric for 5-7 years of UV and weather resistance, or upgrade to premium Sunbrella acrylic for 8-10 years of protection in the harshest offshore environments. Both options are water-repellent, mildew-resistant, and breathable to prevent moisture trapping. Double-stitched seams and reinforced stress points handle repeated trailering without fatigue. Every cover ships with a 2-year manufacturer warranty and arrives within 1-2 business days. For Regulator owners exploring the XO crossover series, the Regulator 24 XO T-Top boat cover delivers the same pattern-cut fit for the hybrid bay-to-offshore platform.
