Cobalt R8 Boats For Sale

The Cobalt R8 is a 27-foot-10-inch bow rider built around a forward-facing stern drive and aimed at families who want one boat for surfing, cruising and entertaining on big open water. It measures 102 inches across the beam, weighs 6,700 pounds, carries 80 gallons of fuel, and is yacht certified, with a 10-gallon freshwater tank feeding the head sink. Cobalt has built boats in the USA since 1968 and became part of Malibu Boats in 2017, which brought surf-system design into the range. The hull uses an elongated running surface and Kevlar-reinforced layup with heavy glass along the keel, and it handles rough, bumpy water without much complaint.

Engine choices include Volvo Penta or the in-house Monsoon block developed with GM. 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, and the Volvo Penta 430 V8 with the Volvo forward-facing drive is also offered. Earlier hulls have shipped with a Volvo Penta 380, and a UK example ran a single 8.2-liter 380-horsepower MerCruiser V8 that burns about 70 liters per hour at 20 knots. The surf wave is shaped through the outdrive trim, dedicated trim tabs and boat speed working together; the default surf setting sits around 11.6 mph with the drive trimmed near 15 degrees, and pushing trim toward 27–30 percent at roughly 11.8–12 mph opens up a longer, cleaner face. Ballast is handled by six hard tanks split into three zones, front and two rear, with three dedicated pumps.

The helm runs twin 10-inch Garmin displays that can be reconfigured for navigation, depth, a fuel-flow burn-rate readout that estimates time on the water, a reverse-facing camera and auto guidance for arrival timing. The power captain's chair swivels and adjusts fore-aft and up-down, with a flip-up bolster, though many drivers stand for clear sightlines over the bow. Controls at the helm include windlass anchor operation, a three-speed heater, trim-tab switches and trim assist for keeping the boat level underway. A 250-amp alternator, full RGB lighting and wireless phone charging are fitted, and the top Harman Kardon audio package adds eight speakers, two subwoofers and four digitally tuned amps across three available sound levels.

Up top, the Prisma power tower folds down with a bimini that articulates parallel to the boat, carries rotating board racks that also accept foils, four optional speakers, center and side tow points, and overhead storage pockets. The cockpit and bow seats fold and tilt into multiple positions, with cavernous storage under every seat, an insulated cooler tub, USB ports and cup holders throughout, plus a removable table insert and bow ski lockers. The transom has a patented flip-down swim step available as a power step, retractable cleats, underwater lights, a rumble seat, an optional transom shower and seven cup holders. When stopping hard, water can wash through the walkthrough and drain via scuppers into the bilge, so easing off the throttle and turning left keeps the deck dry.

Inside the console, the R8 carries a head compartment with a porcelain toilet, electric flush, sink and a small ventilation window, fully lined with no exposed fiberglass. Upholstery is French-stitched, hatches ride on stainless hinges with gas struts, and the gunwale construction pushes interior width and cushion thickness beyond what the 8-foot-6 beam suggests. Interior and exterior colors are configurable, including the heat-reflecting Fresco Chill vinyl and exterior shades such as Bayside Blue. A UK example was priced at £229,000 excluding VAT. For buyers weighing a Cobalt R8 for sale, the boat suits those who want a premium-built cruiser that delivers a genuinely strong surf wave from a single forward-facing drive.
