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.

Robalo 317 DC T-Top Boat Cover — Ultimate Dual Console Protection
The Robalo 317 DC is the brand’s largest dual console — a 31-foot platform that combines offshore fishing capability with family cruising comfort. At 10’6″ beam, 9,050 lbs dry, and up to 800 HP in triple-engine configuration, the 317 DC is a serious boat that demands serious protection. The 21-degree deadrise Hydro Lift™ hull handles open-ocean conditions with Kevlar-reinforced composite construction, while 260 gallons of fuel provide the range for extended trips. Robalo’s Nashville, Georgia manufacturing heritage, dating to their Marine Products Corporation acquisition in 2001, ensures every component meets premium saltwater standards. Browse boat shade kits for additional on-water comfort.
Tailored to the 317 DC’s Premium Dual Console Layout
This cover is pattern-cut to the 317 DC’s spacious 10’6″ beam and unique dual-console deck plan, fitting around the T-Top legs, helm station, passenger console, bow seating with walk-through windshield, enclosed head compartment, aft seating, rod holders, transom fishing station, and optional hardtop extensions. Reinforced cutouts at each T-Top support leg create a tight seal while the hardtop remains exposed. Solo installation takes under five minutes. Handles dock, lift, and dry-stack storage configurations. For the other large Robalo, see the Robalo 272 R T-Top cover.
Protection That Matches the 317 DC’s Premium Investment

Both options shed water, resist mildew, and breathe to protect the 317 DC’s extensive electronics suite, freshwater system, premium upholstery, and dual-console instrumentation. Double-stitched seams and reinforced stress points handle the scale of this platform. A 2-year manufacturer warranty is included.
