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 Cape Horn 31 T cover comes in 9oz solution-dyed marine fabric (rated 5-7 years) or premium Sunbrella acrylic (rated 8-10 years). Both are water-repellent, UV-resistant, and mildew-resistant. The 9oz is available in Navy, Black, and Charcoal.
Yes. The cover pattern extends over the full transom area and accommodates the triple-outboard engine spread. All three powerheads, controls, and rigging are protected from UV and salt corrosion.
Start from the bow, drape the cover over the hull, align the reinforced T-Top cutouts, run the hem cord along the rubrail, and buckle the tie-down straps bow to stern. One person, under 5 minutes, no tools.
Yes. The 9oz fabric handles 5-7 years and Sunbrella handles 8-10 years of continuous outdoor exposure — salt air, direct sun, tropical rain, and sustained wind typical of Southeast and Gulf Coast storage.
Yes. The cover fully encloses the walk-in console including the 13" x 40" flush-mount electronics area. This blocks UV that fades screens and degrades gaskets on multifunction displays.
A 2-year manufacturer warranty covers defects in materials and workmanship. The fabric is rated for 5-7 years (9oz) or 8-10 years (Sunbrella) of outdoor exposure.
Water-resistant with a breathable DWR finish. Sheds heavy rain and dock spray while allowing airflow to prevent mildew — especially important for a boat this size with extensive interior upholstery.
The 31 T is the current-production update with a modernized cockpit layout. While both share the same hull dimensions, each has its own pattern-specific cover to match its unique deck configuration.
Yes, the cover fits all 31 T model years with a factory T-Top. The 31 T is current-production, so the pattern reflects the latest specifications.

Cape Horn 31 T T-Top Boat Cover — Current-Gen Tournament Muscle Under Custom Cover Protection
The Cape Horn 31 T is the current-production evolution of Cape Horn’s proven 31-foot tournament platform — 31’8” with a 9’1” beam and room for 800 HP across triple outboards. The Fabbro family’s 23-degree deadrise hull, foam-filled composite construction, and proprietary cutwater deliver a dry ride even when the Gulf Stream stacks up. With 273 gallons of fuel, a 700-quart insulated fish box, and dual livewells totaling 86 gallons, every component earns its space — and every component needs cover protection when the boat sits between tournaments. A custom-fitted T-Top cover from Perfect Fit Boat Covers keeps the 31 T’s cockpit, electronics, and triple-engine transom shielded from UV, salt, and weather.
Pattern-Cut to the 31 T’s Updated Tournament Cockpit
The 31 T’s walk-in console offers over 6’2” of headroom and a 13” x 40” flush-mount electronics area — serious screen real estate that fades and cracks without cover protection between trips. Twenty-six rod holders, an 85-quart insulated cooler, and the leaning post fill this cockpit with hardware that salt and UV attack relentlessly. This T-Top cover is pattern-cut to the 31 T’s specific layout, with reinforced cutouts that wrap around the T-Top legs and fabric that contours the console and leaning post without bunching. The hem cord cinches at the rubrail, adjustable straps lock the cover down for dock or lift storage, and one person handles the install in under five minutes. The triple-engine transom sits fully under the cover’s protective envelope. The Cape Horn 31 XS T-Top cover fits the same hull family with an expanded seating configuration for anglers who fish with family aboard.
Cover Protection That Matches a Lifetime Transom Warranty
Cape Horn guarantees the 31 T’s hull for 10 years and the transom for life — the cover protecting it should hold up to the same standard. Our 9oz solution-dyed marine fabric handles 5-7 years of sustained salt, UV, and tropical humidity, while premium Sunbrella acrylic extends cover protection to 8-10 years for boats on a lift or in a slip. The breathable DWR finish prevents trapped moisture that breeds mildew on upholstery and corrodes electrical connections under the cover. Double-stitched seams resist dock wind, and the 2-year manufacturer warranty backs every cover we ship. For anglers who want the same foam-filled Cape Horn confidence in a trailerable offshore package, the Cape Horn 24 OS T-Top cover protects a 25-foot hull running 400 HP with 136 gallons of fuel.
