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 340 is EdgeWater's largest dedicated center console — 34'11" on a 10'6" beam with triple outboard capacity up to 900 HP and a 340-gallon fuel tank. At nearly 13,000 lbs dry, this is a purpose-built offshore expedition platform engineered for multi-day runs to distant canyons, remote reef systems, and international fishing grounds. The SPI hull at this scale is an engineering achievement — one-piece, foam-filled, unsinkable construction at 35 feet.
Our cover pattern includes a wider aft section specifically engineered for three-engine configurations. The fabric extends past the transom to envelop all three engine cowlings as one continuous covering — wider than dual-engine models but following the same one-piece design principle. All three lower units remain visible below the fabric edge.
Yes. The 340's wide beam and 35-foot length create substantially more surface area for wind to act on compared to smaller models. Our tie-down system for the 340 uses heavier-gauge straps, wider spacing, and additional attachment points — particularly along the widest section of the beam and around the triple-engine stern area where wind load is highest.
At efficient cruise speeds, the 340-gallon tank delivers roughly 250+ nautical miles of working range. That's enough to reach offshore canyons 100+ miles out, fish all day, and return with comfortable reserves. For tournament anglers running to distant waypoints, this range eliminates the fuel anxiety that limits smaller boats to closer structure.
Larger covers accumulate more salt, debris, and UV exposure. Rinse with fresh water every two weeks minimum — more frequently during peak summer or heavy salt-spray conditions. Full wash with mild soap twice per season. Inspect all tie-down points, stitching seams, and the triple-engine wrap monthly. The additional fabric area means more attachment points to check.
Yes. The cover folds into a provided storage bag sized for the 340's larger cover dimensions. Store in a dry, shaded area. Never store the cover wet — mildew can develop in folded fabric within 48 hours in humid conditions. If the cover gets wet during removal, drape it over the boat rack or dock railing to air-dry before folding.
At nearly 13,000 lbs and 10'6" beam, the 340 is exclusively marina-stored — either in a wet slip or on a heavy-duty dock lift rated for its weight. No standard boat trailer handles this size. Our cover is designed for marina storage environments where salt spray, bird droppings, and UV exposure are constant threats.
The SPI process becomes more valuable as hull size increases. A 35-foot conventionally-built fiberglass hull would rely on thick, heavy layups to achieve structural integrity, adding weight and creating potential delamination points. EdgeWater's vacuum-infused one-piece construction eliminates air pockets, distributes resin evenly, and creates a hull that's stronger and lighter than comparable boats — critical when you're pushing 13,000 lbs through open ocean at speed.
The cover wraps below the T-Top hardtop, leaving all roof-mounted electronics — radar arrays, satellite antenna, LED light bars, and tower components — fully exposed above the cover line. For below-hardtop additions like underslung spreader lights, speakers, or additional rod holders, note them during ordering for pattern adjustments.
The 370 adds another 3+ feet of length, a wider beam, and even larger fuel capacity — it's EdgeWater's ocean-crossing platform. The 340 is the sweet spot for most serious offshore anglers: large enough for extended multi-day trips, manageable enough for a competent two-person crew, and equipped with everything needed for tournament-level fishing.
EdgeWater 340 T-Top Boat Cover
The EdgeWater 340 is the flagship of the Center Console Series — 34’11” of SPI vacuum-infused, one-piece, unsinkable hull carrying triple outboards up to 900 HP and a 340-gallon fuel tank built for expedition-range offshore fishing. At nearly 13,000 lbs dry on a 10’6” beam, the 340 is engineered for the kind of offshore runs where weather windows matter and you need absolute confidence in your hull, power, and fuel reserves. PermaGrid fiberglass structure, 316L stainless throughout, zero wood construction — everything about this boat is built to last.
A Perfect Fit T-Top cover protects the 340’s massive investment — tournament livewells, oversized in-floor fish boxes, complete rigging station, walk-in console, helm electronics suite, and all three outboard engines — in UV-resistant solution-dyed marine fabric. Our triple-engine cover pattern is specifically engineered for the 340’s wider stern section, with a reinforced tie-down system built for the significant wind loads that a 35-foot boat encounters at open-water marina docks.
Expedition-Class Fishing, Expedition-Class Protection
A boat that can run 100+ miles offshore and fish for days deserves protection that matches its capability. The 340 spends its downtime at marina docks where salt spray, UV exposure, and the elements work around the clock to degrade gel coat, corrode hardware, and age electronics. Our T-Top cover eliminates that exposure, keeping the 340 in launch-ready condition between trips so the only thing you’re thinking about is the fishing report. Browse our complete T-Top boat cover collection for every size and brand, or compare the EdgeWater 370 T-Top cover for EdgeWater’s ultimate offshore platform.
