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.

Tidewater 1800 Bay Max T-Top Boat Cover — Compact Bay Boat Protection Built for Skinny Water
The Tidewater 1800 Bay Max packs serious bay boat capability into an 18’2″ hull with a 7’8″ beam and approximately 1,250-lb dry weight. Powered by up to 115 HP and drawing just 8″ of draft, this compact Bay Max was designed in Lexington, South Carolina for anglers who need to reach shallow flats, oyster bars, and backwater marshes that larger boats simply cannot access. With a 37-gallon fuel tank and a 15-degree deadrise modified-vee hull, the 1800 Bay Max handles light chop on open bay water while still floating shallow enough for serious inshore work. A custom-fitted cover from the Tidewater boat covers collection protects every inch of this versatile platform from UV exposure, salt spray, and seasonal weather between trips.
Engineered for the 1800 Bay Max’s Shallow-Draft Layout
This T-Top cover is pattern-cut specifically for the 1800 Bay Max’s compact footprint — wrapping around the T-Top legs, center console, and leaning post while clearing rod holders, livewells, and the forward casting deck. The cover drapes over the hull and secures beneath the rubrail with an integrated hem cord and adjustable strap-and-buckle system. One person can install it in under five minutes, and it stays secure at highway speeds for trailering to your next launch. With just 8 inches of draft, the 1800 Bay Max is built for trailer-friendly ramp access, and this cover is built to protect it on the road. Anglers stepping up from the 1800 Bay Max will find similar coverage for the Tidewater 210 Bay — the next model in the Bay series.
Protection That Matches Tidewater Bay Max Quality
The cover is available in 9oz solution-dyed marine fabric rated for 5-7 years of UV and weather resistance, or premium Sunbrella acrylic for 8-10 years of protection. Both options are water-repellent, mildew-resistant, and breathable to prevent moisture buildup underneath — critical for protecting the 1800 Bay Max’s upholstery, electronics, and gel coat. Double-stitched seams and reinforced stress points ensure long-term durability, and a 2-year manufacturer warranty backs every cover. For complete cockpit enclosure, pair this T-Top cover with a Tidewater 1800 Bay Max center console cover for full protection from bow to stern.
