Cobalt R8 Surf Boats For Sale

The Cobalt R8 Surf is a forward-facing stern drive surf boat measuring 27 feet 10 inches long with a 102-inch beam and a dry weight of 6,700 pounds. It carries 80 gallons of fuel and a 10-gallon freshwater tank that feeds the enclosed head, and the hull is yacht certified. A head compartment with a toilet and sink is rare in the surf category, and it extends the day for cruising, entertaining and open-water running as much as for wakesurfing. This is a single-engine boat suited to families who want one hull that surfs, cruises and handles bumpy water.

Buyers choose between a Volvo Penta forward drive and Cobalt's Monsoon engine, an in-house GM collaboration. The Monsoon comes as a 5.3-liter making 350 horsepower or a 6.2-liter making 430 horsepower with 460 lb-ft of torque, while the Volvo Penta V8 is offered at 380 and 430 horsepower. The wave is shaped through the surf system rather than ballast alone: six hard ballast tanks split into three zones — one forward, two aft — run on three dedicated pumps, totaling roughly 2,600 pounds of ballast. Default surf settings sit around 11.6 mph with the outdrive trimmed near 15 percent; trimming the drive up toward 27 to 30 percent and raising speed to around 12 mph cleans up the face and pushes the rideable pocket well back. The boat lists noticeably to the surf side, and the elevated bow at high trim means standing to drive often gives the clearest view.

The helm pairs twin 10-inch Garmin touchscreens under an eyebrow arch, with customizable readouts including a fuel-flow burn rate, depth, navigation, a reverse-facing camera and an auto-guidance feature that estimates arrival time at a set heading and throttle position. Controls include Lenco trim tabs, trim assist for level running, windless controls, a three-speed heater, wireless phone charging and flush-mount buttons that light when active. The power driver's seat adjusts up, down, forward and back, with a lift-up bolster for a higher view. Rider profiles store wakeboard and surf settings, with wakeboard beginner set at 18 mph. A 250-amp alternator and full RGB lighting are part of the electrical package.

The deck is built around a large open bow with wraparound seating, drainable storage under every seat, cup holders and USB ports throughout, flip-down armrests, and footwell and footrest options on opposing sides. The cockpit offers a wraparound lounge, a removable table insert, an insulated cooler tub and seatbacks that flip forward for a transom-facing lounge useful when spotting riders. At the transom sit a rumble seat, oversized pullout cleats, a transom shower, underwater lights, retractable cleats and a patented flip-down swim step available as a power step. The Prisma power tower carries four additional speakers, rotating board racks that also hold foils, and an articulating bimini that lays parallel when powered down, with side tow points for surfing and a top eye for wakeboarding.

Sound runs through three tiers, topping out with the Harman Kardon system: eight speakers, two subwoofers and four digitally tuned amps. Upholstery is French-stitched, with Fresco Chill vinyl that stays cooler in the sun, and 2026 boats add colored deck options alongside the black deck. The hull uses an elongated running surface and Kevlar-reinforced layup with fiberglass concentrated along the keel. Cobalt, built in Neodesha, Kansas, and owned by Malibu Boats since 2017, has a long-standing reputation for finish quality and strong resale. Points to weigh: the walkthrough transom can let water in through the scuppers if you decelerate too quickly, and trailer mode does not raise the outdrive, so confirm drive position before loading.
