Cobalt R8 Coastal Boats For Sale

The Cobalt R8 is a 27-foot-10-inch open-bow sport boat with an 8-foot-6-inch beam, built in the United States by Cobalt Boats, a manufacturer founded in 1968 and acquired by Malibu Boats in 2017. It carries 125 gallons of fuel and is offered in sterndrive, inboard and outboard configurations, which lets it work as a wakeboard and surf boat, a coastal cruiser and a day-entertaining platform on the same hull. Cobalt pushes the gunnels together during construction to widen the usable interior, so the cockpit and bow feel larger than the 8-foot-6 beam suggests, with thicker cushioning and more seating across the deck.

Power options span a single 8.2-liter MerCruiser V8 producing 380 horsepower with dual-prop drive, a Volvo Penta V8 paired with the forward-facing drive for sharper trim control, and twin Yamaha 300s on the outboard version. The outboard R8 breaks 60 mph at the top end and cruises comfortably at around 32 mph at 2,800 RPM. On the 380-horsepower sterndrive, fuel burn runs about 70 liters per hour at 20 knots, which works out to roughly £122 to cover 20 nautical miles at UK petrol prices, opening to more than double that at wide-open throttle.

The helm is fitted with twin Garmin multifunction displays, available in 10-inch and 12-inch sizes, that split navigation, engine instrumentation, sonar and a reverse-facing camera between screens. Both the Garmin units and the Fusion stereo head are countersunk into the dash rather than surface-mounted, and push-button switches handle lighting and pumps across the boat. Mercury active trim automatically adjusts running angle as people move around, supported by trim tabs and an electric windlass operated from the helm or the bow. The outboard can be optioned with a Hellmaster Level 4 package adding digital throttle and steering, autopilot and a docking joystick. A full drop-down targa arch with board holders, tow points and a Bimini top folds for bridges or towing, raised and lowered by a hidden switch.

Storage runs throughout the deck, with hinged seat boxes on stainless hinges and gas struts, multiple under-floor ski and wakeboard lockers, an insulated cooler with a drain, and a lazarette in the aft cockpit. The transom uses a flip-down swim platform released by a single bolt, with a transom remote for stereo control, cup holders, a phone charger and a 12-volt outlet. The bow seats fold open with one hand, and the captain's-side backrest lifts to reveal a deep storage cavity housing a subwoofer. JL Audio speakers are placed at the transom and in the bow.

A console head compartment is fully lined with no exposed fiberglass, fitted with a porcelain toilet, electric flush and a small opening window for ventilation. The upholstery uses Fresco liner that stays about 20 degrees cooler than ambient air, finished with French and double-diamond stitching, and there are 28 cup holders along with USB ports for passengers. The bow loungers have flip-down armrests and forward-facing bolsters; bow filler cushions can be ordered to extend the seating into a sun pad.

Build details that matter when comparing R8 listings include kevlar-reinforced hulls with added fiberglass along the keel, an elongated running surface for handling, and Cobalt's long-standing reputation for quality that supports strong resale. UK pricing for a new R8 has been quoted at £229,000 excluding VAT. When shopping the R8 for sale, the main variables are the drive choice and engine brand, which directly affect top speed, fuel consumption and helm electronics, and whether the boat carries the wake tower, Hellmaster joystick package and bow filler cushions.
