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 Bay Bolt cover is available in 9oz solution-dyed marine polyester, 7oz solution-dyed polyester, and premium Sunbrella acrylic. All solution-dyed for permanent fade resistance — especially important for bay boats that spend long hours in direct sun on shallow flats and exposed docks.
Yes. Pattern-cut with reinforced cutouts around the T-Top legs. The fabric wraps the Bay Bolt's Kevlar-reinforced 23' hull below the hardtop while the white fiberglass roof stays exposed. The pattern accounts for the Bay Bolt's shallow-draft profile, wider casting platforms, and bay boat-specific deck layout.
Under 5 minutes solo, no tools. Drape from bow over console and T-Top legs, secure with hem cord and straps. The Bay Bolt's 23' length and 8'10" beam are easy for one person.
Yes. Reinforced for highway-speed trailering. Bay boats are among the most frequently trailered fishing boats, and this cover is built for that repeated duty.
Complete barrier over helm, GPS/fishfinder, trolling motor controls, rod holders, and all upholstery. UV, rain, salt spray blocked while breathable fabric prevents mildew in the humid inshore environments where the Bay Bolt fishes.

HydraSport 23 Bay Bolt T-Top Boat Cover — Kevlar Bay Boat Specialist
The HydraSport 23 Bay Bolt measures approximately 23′ overall with an 8’10” beam and roughly 3,500 pounds dry — Hydra-Sports’ dedicated inshore bay boat platform built with the same DuPont Kevlar-reinforced hull construction found in their offshore Vector tournament boats. While most bay boat manufacturers cut corners on hull construction to save weight, Hydra-Sports built the Bay Bolt with hand-laid fiberglass and Kevlar laminate — tri-directional glass sandwiched with Kevlar, no wood anywhere, fully foamed cavities, vinylester gelcoat, and the integrated stringer system bonded with Plexus methacrylate structural adhesive. That means the Bay Bolt handles oyster bars, rocky shorelines, and grounding on sandbars that would crack or puncture lesser hulls. Rated for up to 250 horsepower with approximately 100 gallons of fuel, it’s engineered for skinny-water redfish, trout, and flounder. Browse the full HydraSport boat covers collection from the 212 to the 3300 Vector.
Pattern-Cut for the Bay Bolt’s Inshore Layout
This cover is cut for the Bay Bolt’s shallow-draft hull profile, wider casting platforms, and bay boat-specific deck configuration — a different hull shape and freeboard than the offshore models. The fabric wraps the Kevlar-reinforced hull below the hardtop with reinforced cutouts around the T-Top legs, while the white fiberglass hardtop roof stays fully exposed. A hem cord and adjustable straps secure the cover for trailering — bay boats are among the most frequently trailered fishing platforms on the water. Installation takes under five minutes solo. The smallest model is the HydraSport 212 T-Top boat cover for the compact 21-footer.
Kevlar Through the Oyster Bars, Premium Fabric at the Dock
The Bay Bolt fishes the most corrosive and abrasive environments on the water — shallow salt flats, oyster-studded creek beds, and brackish marshes. Kevlar handles the impacts; your cover handles the elements between trips. Choose 9oz solution-dyed marine fabric for 5-7 years of UV and salt resistance, or premium Sunbrella acrylic for 8-10 years. Both are water-repellent, mildew-resistant, and breathable — essential for bay boats stored in humid marsh environments. Every cover ships with a 2-year warranty within 1-2 business days. For offshore capability, the HydraSport 2500 T-Top boat cover covers the mid-size Vector platform.
