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 Caymas 281 HB cover is available in 9oz solution-dyed marine fabric, a lighter 7oz option, or premium Sunbrella acrylic. The 9oz fabric provides 5–7 years of UV and weather protection, while Sunbrella extends coverage to 8–10 years. All fabrics are solution-dyed for lasting color retention.
Yes. The cover is pattern-cut specifically for the Caymas 281 HB, with reinforced cutouts that fit cleanly around the T-Top legs. The cover wraps the hull beneath the hardtop from bow to stern, leaving the T-Top frame exposed while protecting the console, leaning post, and cockpit.
Installation takes under 5 minutes with no tools required. Drape the cover over the 281 HB from bow to stern, tuck the hem cord along the rubrail, and secure the adjustable tie-down straps. One person can handle the entire process solo.
No — please remove the cover before towing your Caymas 281 HB. 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 console electronics, GPS displays, leaning post upholstery, and cockpit surfaces. It blocks UV rays, rain, salt spray, bird droppings, and airborne debris that degrade equipment over time.
Your Caymas 281 HB 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 and spray to bead and run off. It is intentionally breathable rather than fully waterproof, preventing moisture and mildew buildup underneath during long-term coastal storage.
Yes. The cover fits the Caymas 281 HB with the standard factory T-Top across all production model years. As long as your 281 HB has the factory T-Top configuration, the cover will fit precisely.
The Caymas 281 HB 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.
Shipping is a $30 flat rate per cover within the continental United States. Because every cover is custom-made to order, please allow 1–3 weeks for your Caymas 281 HB cover to be made and shipped — you'll receive tracking information as soon as it leaves our facility.

Caymas 281 HB T-Top Boat Cover — Triple-Engine Bay Boat Armor
The Caymas 281 HB takes the proven HB platform to its most capable form — 27’11” of 100% composite construction with a 9’4″ beam, 4,300 lbs dry weight, and the ability to run triple outboards up to 600 HP total. Earl Bentz founded Caymas in 2018 in Ashland City, Tennessee, and built every model around the patented Michael Peters SVVT hull — a Stepped V Ventilated Tunnel design that planes faster, burns less fuel, and runs shallower than conventional hulls at the same length. The 281 HB carries 200 gallons of fuel for extended-range missions where inshore meets offshore, and the tournament-grade livewell system keeps bait alive from dawn to weigh-in. A custom-fitted cover from Perfect Fit keeps the Caymas boat covers collection dialed in, shielding the 281 HB’s console, triple engine rigging, and cockpit electronics from UV, salt, and weather damage between trips.
Tailored to the 281 HB’s Triple-Powered Layout
This cover is pattern-cut to the 281 HB’s specifications, accounting for the wider transom section that accommodates triple outboard rigging. Reinforced cutouts wrap cleanly around the T-Top legs while leaving the hardtop exposed, and the cover drapes over the center console, leaning post, rod holders, and gunwale accessories without bunching or leaving gaps. Installation takes under five minutes solo — drape from bow to stern, set the hem cord at the rubrail, and buckle the tie-down straps. Remove the cover before towing — it’s designed for storage, not highway travel. For anglers running the standard single-engine HB models, the Caymas 26 HB cover delivers the same precision fit in a lighter package.
Protection That Matches Caymas Lifetime Hull Warranty
Caymas backs every hull with a limited lifetime structural warranty — your cover should deliver the same long-game durability. The 9oz solution-dyed marine fabric provides 5–7 years of UV and weather resistance, while the premium Sunbrella acrylic option extends that to 8–10 years. Both fabrics are water-repellent, mildew-resistant, and breathable enough to prevent condensation buildup during humid coastal storage. Double-stitched seams and reinforced stress points handle repeated use and seasonal storms. Every 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. Anglers stepping into the offshore catamaran lineup will find the same custom-fit quality in the Caymas 34 CT cover.
