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 230 Dauntless T-Top cover is available in 9oz solution-dyed marine fabric (rated 5-7 years), a lighter 7oz option for sheltered storage, or premium Sunbrella acrylic (rated 8-10 years). All fabrics are water-repellent, mildew-resistant, and UV-protective.
Yes. The cover is pattern-cut specifically for the Boston Whaler 230 Dauntless T-Top, with reinforced cutouts that wrap cleanly around the T-Top legs. The hardtop remains exposed while the cover protects everything below.
Installation takes under 5 minutes with one person. Simply drape the cover from the T-Top frame, pull it down to the rubrail, secure the adjustable tie-down straps, and buckle everything tight. No tools required.
No — please remove the cover before towing your Boston Whaler 230 Dauntless. Our covers are not designed to be trailered: towing with the cover on can cause severe damage to the cover and voids the warranty. The cover is designed for storage only — on a trailer, boat lift, dry stack, or jet dock — and comes off in minutes at the ramp.
Yes. The cover creates a complete barrier over the cockpit, shielding your console electronics, GPS, fishfinder, upholstery, and gelcoat from UV rays, rain, salt spray, bird droppings, and debris.
Your Boston Whaler 230 Dauntless cover is backed by our manufacturer's warranty for the original purchaser. Materials and workmanship — stitching, straps, buckles, zippers, and other hardware — are covered for 1 year from the purchase date. Fabric is covered for 3 years on 7oz, 5 years on black or navy 9oz, and 6 years on Sunbrella. Covered defects are repaired or replaced after you contact us for a Return Merchandise Authorization (RMA) number. The warranty does not cover improper use, accident or negligence, unauthorized modifications, improper care, mold or mildew, incorrectly placed orders, theft or loss, or acts of God — and traveling with the cover on or using it in the water voids the warranty. See our Warranty page for full details.
The cover is water-resistant with a durable water repellent (DWR) finish that causes rain to bead and roll off. The breathable construction prevents trapped moisture and condensation buildup underneath, which protects against mildew.
This cover is designed for the Boston Whaler 230 Dauntless equipped with a factory T-Top. It fits standard production models across model years with the same T-Top configuration.
The Boston Whaler 230 Dauntless cover is available in 9oz solution-dyed polyester in Navy or Black, 7oz polyester in Black, or premium Sunbrella acrylic in Marine Blue, Black, or Smoke. Choose your fabric and color in the order options above.

Boston Whaler 230 Dauntless T-Top Boat Cover — Mid-Range Crossover, Complete Protection
The Boston Whaler 230 Dauntless measures 23’6″ with an 8’6″ beam and roughly 3,100 pounds dry, driven by a single 300-horsepower outboard with approximately 80 gallons of fuel. A 16-degree deadrise balances a smooth offshore ride with the shallow 12-inch draft that lets you probe tidal creeks and back-bay flats without a second thought. Built on the foam-cored “Unibond” hull that has defined Boston Whaler’s unsinkable reputation since 1958, the 230 Dauntless delivers a roomy cockpit with convertible bow seating, integrated rod storage, a raw-water washdown, and a transom livewell — everything a coastal angler or weekend cruiser could ask for. A custom-fitted T-Top cover from Perfect Fit Boat Covers wraps the entire hull below the hardtop, shielding the console, leaning post, electronics, and upholstery from UV exposure, rain, and salt spray between trips.
Tailored to the 230 Dauntless’s Crossover Layout
Every Perfect Fit T-Top cover is pattern-cut to the 230 Dauntless’s specific hull geometry, with reinforced cutouts that seat cleanly around the T-Top legs without sagging or excess fabric. A sewn-in hem cord traces the rubrail while adjustable tie-down straps lock the cover from gunwale to gunwale. Installation takes one person under five minutes — drape from the hardtop frame, pull to the rails, strap, buckle, and walk away. The reinforced construction holds tight with zero flutter. Remove the cover before towing — it’s designed for storage, not highway travel. Owners moving up in the Dauntless lineup will find the same meticulous fit on the Boston Whaler 240 Dauntless T-Top cover as well.
Marine-Grade Fabric for Coastal Durability
Your cover ships in your choice of 9oz solution-dyed marine fabric rated for 5–7 years of hard use, 7oz performance-weight fabric ideal for covered storage, or premium Sunbrella acrylic engineered to last 8–10 years in direct sun. Every option is water-repellent, mildew-resistant, and double-stitched at every seam for long-term durability. The breathable fabric prevents trapped moisture while blocking 99% of UV rays — essential protection for the 230 Dauntless’s console electronics and premium seating. Each cover is backed by our warranty (1 year on materials and workmanship, plus 3–6 years on the fabric) and ships within 1–3 weeks for a $30 flat rate to the continental US. If your fleet includes a smaller Boston Whaler, check out the Boston Whaler 150 Sport center console cover built with the same premium construction. For additional cockpit shade while at anchor, explore the center console curtain — a popular add-on for Dauntless owners who spend long days on the water.
