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 Glacier Bay 2665 T-Top cover is available in 9oz solution-dyed marine fabric or premium Sunbrella acrylic. The 9oz fabric delivers 5–7 years of UV and weather protection, while Sunbrella extends that to 8–10 years. Both are water-repellent, mildew-resistant, and double-stitched at all seams.
Yes. The cover is pattern-cut with reinforced cutouts that wrap around the T-Top support legs. The fabric covers the hull below the hardtop while the white fiberglass T-Top roof remains fully exposed on top.
Installation takes under five minutes. Drape the cover over the hull from bow to stern, position it around the T-Top legs using the reinforced cutouts, then secure the adjustable tie-down straps and buckles at the rubrail. One person can install it without assistance.
Yes. The cover is reinforced for highway-speed trailering with heavy-duty stitching and secure strap-and-buckle tie-downs that keep the fabric tight against the hull at speed.
Absolutely. The Glacier Bay 2665 T-Top cover creates a complete barrier over the cockpit, protecting your electronics, helm station, upholstery, fishbox hatches, and livewell systems from UV damage, rain, salt spray, bird droppings, and debris.
Every Glacier Bay 2665 T-Top cover includes a 2-year manufacturer warranty covering defects in materials and workmanship.
The cover is water-resistant with a durable water repellent (DWR) finish that causes water to bead and roll off. It is intentionally breathable rather than fully waterproof — this prevents moisture and mildew buildup underneath the cover, which is critical for long-term boat storage.
Yes. The cover fits all Glacier Bay 2665 Canyon Runner models with the factory T-Top during standard production years (2005–2008). The 2665 shares the same hull as the earlier 260 Canyon Runner, so if your boat was sold under the 260 Canyon Runner name, check our listing for that model.
The 9oz solution-dyed fabric is available in Navy, Black, and Charcoal. The premium Sunbrella acrylic offers an expanded palette including Pacific Blue, Forest Green, Burgundy, and additional colors.
Shipping is a flat rate per cover for delivery anywhere in the continental United States. Most orders ship within 1–2 business days.
Glacier Bay 2665 T-Top Boat Cover — Catamaran-Grade Offshore Protection
The Glacier Bay 2665 Canyon Runner is a 26’1″ twin-hull power catamaran built for serious offshore fishing. Weighing approximately 4,200 lbs with an 8’9″ beam, the 2665 runs on twin outboards up to 300 HP combined and carries 180 gallons of fuel for extended bluewater range. The twin-hull catamaran design delivers exceptional stability in rough seas, making these boats favorites among tournament anglers and offshore enthusiasts. Though Glacier Bay ceased production, the 2665 remains one of the most capable trailerable catamaran fishing platforms ever built. A custom-fitted T-Top cover from Perfect Fit’s center console curtain collection shields the 2665’s expansive cockpit, twin fishboxes, and electronics from UV damage, salt spray, and seasonal weather — keeping this legacy platform protected between trips.
Tailored to the 2665’s Twin-Hull Catamaran Layout
This cover is pattern-cut specifically for the Glacier Bay 2665’s unique catamaran beam and T-Top footprint. The fabric wraps below the hardtop with reinforced cutouts around the T-Top support legs, draping over the wide cockpit, oversized fishbox hatches, and leaning post while the white fiberglass hardtop remains fully exposed. Installation takes under five minutes — simply drape the cover over the hull, secure the adjustable straps and buckles at the rubrail, and the 2665 is protected. The cover is reinforced for highway trailering, and with the 2665’s 2’4″ draft, you’ll have no trouble getting this catamaran on and off the ramp. If you’re also covering a Glacier Bay 260 Canyon Runner, note that both share the same hull — the 2665 designation applies to 2005–2008 model years.
Protection That Matches Glacier Bay Engineering
Glacier Bay built these catamarans to handle open ocean conditions, and your cover should match that durability. Choose from 9oz solution-dyed marine fabric rated for 5–7 years of UV and weather resistance, or upgrade to premium Sunbrella acrylic for 8–10 years of protection. Both options are water-repellent, mildew-resistant, and double-stitched at every seam. The fabric breathes to prevent moisture buildup beneath the cover while blocking damaging UV rays that degrade gel coat, upholstery, and electronics. Every cover ships with a 2-year manufacturer warranty. For additional cockpit shade while on the water, check out our Twin Vee 26 T-Top cover — another twin-hull platform built for offshore performance.
