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
Our standard cover for the 188 Triton uses 9 oz solution-dyed marine-grade polyester — a tightly woven fabric that resists UV fading, mildew, and water penetration while remaining light enough to drape smoothly over the Triton's compact 18'8" hull. We also offer a 7 oz polyester option for budget-friendly protection and a premium Sunbrella acrylic upgrade for maximum longevity in harsh coastal climates. All three fabrics are treated with a durable water-repellent finish and engineered to breathe so moisture doesn't get trapped against your gel coat.
The cover is custom-patterned to create a single tent-like shape that peaks at the center console and Yamaha Digital Command Link gauge pod, then slopes gradually down in every direction — over the windscreen, past the leaning post, and down to the transom and bow. There are no separate pieces or gaps around the console base. The fabric rises cleanly over the 188 Triton's console without bunching against the Baystar hydraulic steering helm, and it drapes past the gunwale rod holders and recessed stainless steel cleats without catching or snagging.
Installation takes under five minutes solo. Start by draping the cover over the center console so the peak sits centered over the windscreen. Pull the fabric forward toward the bow and aft toward the transom, then down each side past the gunwales. Secure the hem cord along the stainless steel rub rail, then fasten the adjustable tie-down straps underneath the hull. The cover's pattern accounts for the 188 Triton's 7'9" beam and flared bow entry, so everything lines up without pulling or guesswork.
Yes — the cover is reinforced at every high-stress point for trailering at highway speeds. Double-stitched seams at the bow eye, console base, and cleat locations resist the vibration and wind load that destroy generic covers during towing. The adjustable straps cinch tight underneath the hull to prevent billowing, and the hem cord locks along the rub rail to keep the cover seated. The 188 Triton's relatively light weight and 18'8" length make it one of the most frequently trailered Sea Hunt models, and our cover is built for that exact use case.
Absolutely. The cover creates a complete barrier over every exposed surface — the Yamaha Digital Command Link gauges, fishfinder screen, Baystar hydraulic steering helm, leaning post cushion, and all cockpit upholstery sit fully sealed beneath the fabric. UV rays, rain, salt spray, bird droppings, and pollen are blocked from reaching these surfaces. The 188 Triton's 40-quart insulated console cooler, 105-quart bow storage box, and 20-gallon aft livewell are all enclosed as well, keeping hardware clean and reducing maintenance between trips.
Every cover ships with a 2-year manufacturer warranty covering defects in materials and workmanship — stitching failures, fabric delamination, hardware corrosion, and snap or buckle breakage. The warranty applies regardless of whether you store your 188 Triton on a trailer, at a dock, or under a carport. Beyond the warranty period, the 9 oz solution-dyed fabric typically delivers 5 to 7 years of reliable service, and the Sunbrella upgrade pushes that to 8 to 10 years in full-sun southern climates.
The cover is water-resistant with a durable water-repellent (DWR) finish that causes rain and spray to bead and roll off rather than soaking through. It is intentionally not sealed waterproof — a fully sealed cover would trap moisture underneath and promote mildew growth on the 188 Triton's upholstery and gel coat. The breathable construction allows air to circulate beneath the fabric while still blocking 99 percent of direct water contact, which is the ideal balance for both trailered storage and extended dockside mooring.
The cover is patterned to fit the standard-production Sea Hunt 188 Triton with the factory center console configuration. Sea Hunt has kept the 188 Triton's core hull dimensions — 18'8" LOA, 7'9" beam, and Vortec hull with 16-degree deadrise — consistent across production years, so the cover fits all standard model years. If your particular boat has significant aftermarket modifications like an oversized T-top, tower, or extended swim platform, contact us to confirm fitment before ordering.
The 9 oz solution-dyed polyester is available in Navy, Black, and Charcoal — three neutral marine colors that complement any hull color or gel coat. If you upgrade to Sunbrella acrylic, the palette expands to include additional shades such as Captain Navy, Pacific Blue, and Forest Green. Every color option uses solution-dyed fiber, meaning the pigment is embedded during manufacturing rather than applied to the surface, so the color stays true for years without fading under direct UV exposure.
Shipping is a flat rate of $30 per cover to anywhere in the continental United States. Orders typically ship within 1 to 2 business days and arrive via ground carrier. The 188 Triton cover ships folded in a compact box that's easy to handle, and every order includes all mounting hardware — stainless steel snaps, adjustable straps, and hem cord — so you're ready to install as soon as the box arrives.
Why Your Sea Hunt Triton 188 Deserves a Custom-Fitted Cover
The Sea Hunt Triton 188 is one of the most capable inshore center consoles in its class. At 18’8″ with a 7’9″ beam, a proprietary Vortec hull with 16-degree deadrise, and room for up to 150 HP on the transom, the Triton 188 handles coastal bays, grass flats, and nearshore runs with the confidence of a much larger boat. Our custom center console mooring cover is patterned from the Triton 188’s exact hull shape — wrapping the flared bow entry, rising cleanly over the console with its Yamaha Digital Command Link gauges and Baystar hydraulic steering, and draping down past the rear jump seats to the transom in one seamless, form-fitting shape that no generic cover can replicate.
Built for the Triton 188’s Feature-Packed Deck
Sea Hunt loaded the Triton 188 with fishing-first features — a 20-gallon aft livewell with high-speed pickup, a 40-quart insulated console cooler, a 105-quart insulated bow storage box, gunwale rod holders, under-gunwale rod storage, and recessed stainless steel cleats. Our cover accounts for every one of these elements in the pattern. The fabric rises over the center console and windscreen without bunching, then follows one gradual slope from the console peak down to the swim platform. There are no loose spots where wind can push underneath and no tight areas that stress the fabric over hardware. Reinforced stitching at the bow eye, console base, and every cleat location means this cover handles trailering at highway speeds and months of outdoor storage equally well. Choose from our 9 oz marine-grade canvas — by far the most popular option — or upgrade to Sunbrella for maximum UV and mildew resistance in harsh southern climates.
How Our Covers Keep Your Triton 188 Ready to Fish
Sun, salt air, rain, and bird droppings attack gel coat, upholstery, and electronics every day your boat sits uncovered. A properly fitted mooring cover blocks all of it while allowing enough airflow to prevent moisture buildup underneath. Our attachment system uses stainless steel snaps, adjustable straps, and a hem cord that cinches tight along the stainless steel rub rail — creating a wind-resistant seal whether your Triton 188 lives on a trailer, at a dock, or under a carport. Browse our complete collection of custom boat covers to see how we protect every model on the water. Anglers who also fish the Triton series will want to see our cover for the Sea Hunt 225 Triton T-Top, and if you own the non-Triton hull, check out our dedicated Sea Hunt 188 center console cover as well.
