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. Our Sea Hunt 21 XP Bay covers are custom-patterned to fit this specific model's hull profile and deck layout — the raised forward casting platform, center console with electronics, leaning post with rod holders, and aft casting deck with live well. The pattern accounts for the XP 21's 7'9" beam and modified-V hull shape, so the cover fits snugly without bunching around the console or leaving gaps at the bow. Simply select your model year and any aftermarket accessories during checkout.
Since the center console version has no T-top frame, the cover wraps over the entire boat as one continuous piece from bow to stern. It attaches along the rubrail and gunwale using stainless-steel snaps, adjustable straps, and an elastic hem cord that holds the bottom edge snug against the hull. A support pole system prevents water from pooling on the flat areas of the cover, particularly over the forward casting platform and aft deck.
Our covers extend well below the chine — the widest point of the hull where it transitions from the vertical sides to the V-bottom. On the 21 XP Bay, only a thin 6–10 inch strip of the curved V-bottom hull is visible below the cover's bottom edge. When trailered, the cover's bottom edge sits level with the top of the trailer tires, and tie-down straps secure it to the trailer frame for a tight, wind-resistant fit during highway travel.
The cover is one single continuous piece of fabric — it doesn't stop at the transom. The fabric extends past the transom and drapes loosely over the outboard engine as part of the same cover, then gathers and cinches at the bottom with straps. The engine is completely hidden under the fabric — you can't see the cowling shape at all. Only the lower unit shaft is visible below. There is no separate engine boot or engine cover to deal with.
Yes. Bay boat owners frequently add trolling motors, Power-Poles, jack plates, poling platforms, and upgraded electronics to the XP 21. During the ordering process, you'll specify any aftermarket additions and our team adjusts the pattern to accommodate these modifications. This ensures the cover fits properly without putting stress on protruding accessories or leaving gaps around them. We include a Power-Pole measurement form for precise fitment.
Absolutely. The 21 XP Bay is a popular trailer boat at roughly 2,150 pounds dry weight, and many owners tow it regularly. Our covers feature reinforced tie-down points, heavy-duty adjustable straps, and a custom fit that minimizes wind catch and flapping at highway speeds. The snug fit around the XP 21's hull contours means the cover won't balloon or shift during transit, which prevents both cover damage and scratching to the boat's gel coat.
With proper care, our covers typically last 7–10 years in harsh saltwater and sun environments like the Gulf Coast, Florida flats, and the Carolina marshes — exactly the waters where the XP 21 excels. Both our 9 oz marine canvas and Sunbrella options use solution-dyed fibers that resist UV fading and mildew growth. We recommend rinsing the cover with fresh water after heavy salt exposure and allowing it to dry fully before folding for maximum lifespan.
A center console mooring cover is a full-boat cover designed to wrap over the entire vessel — from bow to stern and down the hull sides — providing complete protection during storage or trailering. Unlike a bimini top (which only provides shade while underway) or a T-top cover (which attaches to the T-top frame), a CC mooring cover has no overhead structure to clip onto. It relies on snaps along the gunwale, internal support poles for water shedding, and adjustable straps to create total coverage of the boat, console, and engine as one continuous piece.
Both are outstanding marine-grade fabrics. The 9 oz canvas is our best-selling option — it's heavy-duty, tightly woven, and delivers excellent water resistance, UV protection, and breathability at an attractive price point. It carries a 5-year fabric warranty. Sunbrella is the premium choice, offering superior fade resistance and longevity with a 6-year warranty, and is often preferred by owners who store their boats in intense sun climates like South Florida, the Texas coast, or the Bahamas. Both fabrics are solution-dyed, so the color goes all the way through the fiber and won't transfer to your gel coat.
Select your Sea Hunt 21 XP Bay from our product page, choose your preferred fabric (9 oz canvas or Sunbrella) and color, then note any aftermarket accessories during checkout. Each cover is built to order using your boat's specific pattern and model year. Typical production time is 2–4 weeks depending on volume. Your cover ships with everything needed for installation — stainless-steel snaps, adjustable straps, support poles for water shedding, and step-by-step installation instructions. No additional hardware purchases required.
Sea Hunt 21 XP Bay Boat Cover — Custom-Fitted Center Console Protection
The Sea Hunt 21 XP Bay is one of the most capable inshore bay boats in its class — a 21’2″ modified-V hull with a 7’9″ beam, shallow 12-inch draft, and enough fuel capacity to run tidal flats and coastal bays all day long. Our custom-patterned center console cover is built specifically for the XP 21’s hull profile, center console layout, and flush-mount rod holders, delivering a tight fit that sheds water cleanly and keeps every surface protected between trips.
Unlike universal covers that bunch around the console or leave the bow exposed, our XP Bay 21 cover follows the boat’s exact contours — from the raised bow platform down through the center console and leaning post to the aft casting deck. The result is clean coverage with no wind-catching slack, no pooling pockets, and no gaps where rain or debris can reach your electronics, upholstery, or gel coat.
Why the Sea Hunt 21 XP Bay Needs a Dedicated Cover
With a single outboard rated up to 200 HP, 58 gallons of fuel, and a 15-degree deadrise hull built for skinny water, the XP 21 lives in some of the harshest environments on the coast — salt flats, mangrove creeks, oyster bars, and sun-baked trailer lots. That constant exposure to UV, salt spray, humidity, and airborne debris accelerates wear on everything from the console gauges to the leaning post cushion and the gel coat finish.
At roughly 2,150 pounds dry weight, the 21 XP Bay is a trailer-friendly boat that often sits in driveways, open storage lots, or on lifts between trips. A properly fitted cover is the single most effective way to slow UV oxidation on the hull, prevent mildew from colonizing the casting deck cushions, and stop corrosion on exposed stainless hardware. Owners who cover their boats consistently report significantly better resale values and lower annual maintenance costs. Whether you’re fishing the Perfect Fit Boat Covers lineup or just looking for the right protection, a custom pattern is the way to go.
Built for the Sea Hunt XP 21 Bay Boat Layout
Every cover we produce for the 21 XP Bay is patterned around the boat’s specific deck layout: the raised forward casting platform with integrated storage, the center console with its T-top mounting plate (or open top on CC models), the leaning post with rod holders, and the aft deck with live well access. The fabric follows the modified-V hull shape all the way below the chine to the rubrail, so water runs off instead of collecting.
We offer your choice of 9 oz marine-grade canvas — our most popular option for the XP Bay — or premium Sunbrella fabric. Both are solution-dyed for maximum UV and fade resistance, meaning the color is locked into the fiber itself rather than applied to the surface. Each cover ships with stainless-steel snaps, adjustable straps, support poles, and complete installation hardware. If you fish similar waters, check out the Sea Hunt 24 Edge T-Top cover for a larger platform option, or see the Sea Hunt 19 XP center console cover for a more compact bay boat setup.
How Our Covers Protect Your Investment
A custom-fitted mooring cover does more than keep leaves out of your boat. It preserves your resale value by shielding the gel coat from UV oxidation, prevents mildew from forming on the casting deck cushions and leaning post upholstery, and stops corrosion on exposed hardware and electronics. For a dedicated inshore bay boat like the XP 21 that sees constant salt exposure and extended outdoor storage, that protection translates directly into lower maintenance costs and a longer hull life.
