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
You can choose between our 9oz solution-dyed marine fabric, which offers 5–7 years of UV-resistant protection with excellent color retention, or our premium Sunbrella acrylic, which provides 8–10 years of service in the most demanding saltwater environments. Both options are water-repellent and mildew-resistant.
The cover wraps the entire hull and cockpit below the hardtop while the T-Top frame remains exposed above. It is patterned to fit around the T-Top legs, center console, leaning post, and rod holders without requiring any cutting or modification. The hardtop stays uncovered so it continues to shed rain naturally.
Installation takes under five minutes for a single person. Our strap-and-buckle system uses a hem cord that seats at the rubrail and adjustable tie-down straps that lock the cover in place — no tools, frames, or extra hardware needed.
Yes. The cover is designed to stay secure during trailering at highway speeds. Reinforced stitching and adjustable tie-down straps prevent flapping, lifting, or shifting so you can tow with confidence from storage to the ramp.
Yes. The cover shields the full cockpit area below the T-Top, including helm-mounted electronics, multifunction displays, and fish finders. Blocking UV exposure, rain, and airborne salt extends the life of sensitive screens and electrical components.
Every cover includes a 2-year warranty against defects in material and workmanship. This warranty applies equally to both the 9oz solution-dyed marine fabric and the premium Sunbrella acrylic option.
The cover is water-repellent, not fully waterproof. This is a deliberate design choice — a breathable, water-repellent fabric sheds rain and spray while allowing trapped moisture to evaporate, which prevents mildew and condensation buildup beneath the cover in humid conditions.
This cover is custom-fitted to the Robalo 266 Cayman SD hull dimensions. It fits all production model years of the Sand Bar edition. If your boat has aftermarket modifications or unique accessories, contact us to confirm fitment before ordering.
We offer a broad selection of colors in both the 9oz solution-dyed marine fabric and Sunbrella acrylic lines. Popular choices include navy, black, charcoal, and lighter shades that reduce heat absorption. You can select your color during checkout.
Shipping is a flat rate of $299 for all T-Top boat covers, delivered anywhere in the continental United States. Your cover typically ships within 4–6 weeks of order placement.
⏱️ Current lead time: 1–3 weeks — every cover is custom-made for your boat.

Robalo 266 Cayman SD T-Top Boat Cover — Sand Bar Edition Protection for Shallow-Water Hunters
The Robalo 266 Cayman SD brings 26’6″ of bay boat capability to anglers who work the flats, sandbars, and inshore shallows where bigger boats cannot follow. With a 9’4″ beam, 18-degree deadrise, and a skinny 18″ draft, the Sand Bar edition of the 266 Cayman is purpose-built for shallow-water fishing while still handling open-bay chop. Robalo has been manufacturing fishing boats since 1968, and the brand — now built near Nashville, Tennessee — carries decades of saltwater heritage into every hull. Powered by up to 450 horsepower, carrying 110 gallons of fuel, and weighing roughly 6,200 lbs ready to run, the 266 Cayman SD is a serious machine that deserves serious protection. Our custom-fitted T-Top boat cover keeps the cockpit, console, and deck sealed against sun, rain, and salt between trips. Browse our full lineup of Robalo boat covers to find covers for every model in the fleet.
Tailored to the 266 Cayman SD’s Bay Boat Layout
The Sand Bar edition features a layout built around shallow-water fishing — raised casting platforms, a center console with T-Top, a leaning post, bow and aft live wells totaling 50 gallons, and rod holders positioned for quick access when reds are tailing. Our cover is patterned to accommodate every one of these features, wrapping below the T-Top frame while accounting for the console profile, leaning post, and gunwale-mounted rod holders. The hem cord locks at the rubrail, and adjustable tie-down straps pull everything snug so the cover stays put in wind, rain, and highway miles. One person can install it in under five minutes with no tools required. The cover is fully trailerable, keeping your 266 Cayman SD protected from the garage to the ramp. If you own the standard deep-vee variant, our Robalo 266 Cayman T-Top boat cover provides the same precision fit on that hull.
Protection That Matches Robalo Quality
Robalo has spent more than five decades refining fishing boats for saltwater conditions, and the cover protecting your 266 Cayman SD should reflect that same commitment to durability. Our 9oz solution-dyed marine fabric delivers 5–7 years of reliable UV resistance, color retention, and mildew protection, while the premium Sunbrella acrylic upgrade extends service life to 8–10 years for owners who demand the longest-lasting option available. Both fabrics are water-repellent and finished with double-stitched seams at every stress point. A 2-year warranty backs every cover we ship. Anglers shopping for a similar-sized center console cover may also want to see our Cobia 245 CC T-Top boat cover — another proven coastal fishing platform in the mid-twenties range.
