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
The 266 Cayman cover is available in 9oz solution-dyed marine fabric (5–7 years) or premium Sunbrella acrylic (8–10 years). Both are water-repellent, mildew-resistant, and built for humid coastal conditions.
Yes. Pattern-cut reinforced cutouts wrap each T-Top leg. Hardtop stays exposed; the twin-engine bay boat cockpit is fully covered.
Under five minutes, solo. Drape, strap, buckle, cinch the hem cord along the rubrail.
No — please remove the cover before towing your Robalo 266 Cayman. 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. Complete barrier over electronics, lean bar, casting platform, livewells, rod storage, and all seating.
Your Robalo 266 Cayman 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.
Water-resistant with DWR finish. Breathable to prevent moisture buildup.
Yes. Fits standard production years with factory T-Top.

The Robalo 266 Cayman is the flagship of the Cayman series — a 26’6″ bay boat with twin-engine capability that bridges the gap between inshore versatility and nearshore range. With a 9’4″ beam, 18-degree deadrise, and up to 400 HP in twin configuration, the 266 Cayman carries 110 gallons of fuel at 4,500 lbs dry and drafts just 17 inches when trimmed up. This is a bay boat built for anglers who want to chase reds on the flats in the morning and run to nearshore wrecks in the afternoon. Robalo’s Kevlar-reinforced Hydro Lift™ hull construction delivers a dry ride across varied conditions — heritage engineering from Nashville, Georgia since 1968. Browse T-Top boat covers for the full Robalo lineup.
Tailored to the 266 Cayman’s Twin-Engine Bay Platform
Pattern-cut to the 266 Cayman’s wide 9’4″ beam and twin-engine layout, this cover fits around the T-Top legs, center console, lean bar, forward and aft livewells, bow casting platform, rod holders, and the expanded cockpit that makes the 266 the most versatile Cayman in the lineup. Reinforced cutouts at each T-Top support leg ensure a clean seal while the hardtop remains exposed. Solo installation takes under five minutes. Remove the cover before towing — it’s designed for storage, not highway travel. For the entry-level Cayman, see the Robalo 206 Cayman T-Top cover to complete the series.
Protection for the Ultimate Bay Boat
Select 9oz solution-dyed marine fabric for 5–7 years of UV and weather resistance, or Sunbrella acrylic for 8–10 years. Both are water-repellent, mildew-resistant, and breathable to handle the humid environments where bay boats operate. Double-stitched seams and reinforced stress points ensure the cover performs through seasons of use. Our warranty (1 year on materials and workmanship, plus 3–6 years on the fabric) is included. For a similar-size offshore alternative, also explore the Robalo 272 R T-Top cover.
