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 2100 Bay T-Top Boat Cover — 21-Foot Bay Boat Built for Skinny Water
The Tidewater 2100 Bay stretches the Bay series to 21’6″ with an 8’2″ beam, approximately 2,100-lb dry weight, and power options up to 200 HP on a single outboard. This is a purpose-built bay boat — the 15-degree deadrise modified-vee hull and 10-inch draft let you reach oyster bars, grass flats, and tidal creeks that deeper-draft center consoles simply cannot access. A 56-gallon fuel tank gives the range for full-day exploration across expansive bay systems, and the hull’s stability handles light chop on open water crossings. Tidewater builds the 2100 Bay in Lexington, South Carolina with the same attention to angler-focused detail that defines the entire lineup. Browse the full collection of T-Top boat covers for protection across every hull in your fleet.
Pattern-Cut for the 2100 Bay’s Bay Boat Configuration
This cover is tailored to the 2100 Bay’s specific hull profile — a bay boat layout with the T-Top frame, center console, leaning post, dual livewells, rod holders, and the forward casting deck that serious inshore anglers demand. Reinforced cutouts fit cleanly around T-Top legs, and the cover drapes over the full hull with no excess material or gaps. The strap-and-buckle system locks everything down in under five minutes, solo, and the hem cord secures beneath the rubrail for a wind-tight fit at highway speed. With just 10 inches of draft, the 2100 Bay launches from the shallowest ramps and trailers effortlessly. For the upgraded BayMax variant, check the Tidewater 2110 BayMax T-Top cover.
Marine-Grade Protection for Coastal Bay Environments
Bay boats spend their lives in punishing conditions — salt marshes, sun-scorched flats, and humid coastal air year-round. The 2100 Bay cover is available in 9oz solution-dyed marine fabric rated for 5-7 years of UV and weather protection, or premium Sunbrella acrylic for 8-10 years of service. Both fabrics feature water-repellent DWR finish, mildew resistance, and breathable construction that prevents trapped condensation from damaging the 2100 Bay’s upholstery, electronics, and gel coat. Double-stitched seams reinforce every stress point, and a 2-year manufacturer warranty covers materials and workmanship. For complete hull protection, also explore the Tidewater 2110 Bay Max center console cover for bow-to-stern enclosure.
