2025 Cobalt R4 Surf

Developed to meet the needs of day-boater families, the R4 Surf incorporates a revolutionary hull design for vastly improved wave generation, storage and performance. Managing waves is simplified with the new Cobalt Custom-Wave Technology, powered by Volvo Penta, that allows for up to 20 savable rider profiles, among other features, to improve a day on the water. This combination, along with the patented SurfGate technology, delivers both a smooth Cobalt ride and perfect waves for an ideal surfboard and wake-board experience. Power comes from an array of Volvo Penta Forward Drive options that can generate up to 430 hp. Standard features include a 6-speaker audio system with AM/FM stereo with Bluetooth and an iPod/USB/MP3 port, such interior appointments as a dual Garmin glass cockpit, gloss black switch panels with illuminated switches, accessory and USB power plugs, a depth and water-temp package, removable aft, cockpit and bow carpet, walk-through bow door, aft sunpad folding backrest, a flip-backrest passenger seat and a Delmar captain’s chair. Standard exterior amenities include an anchor locker, stainless bow scuff plate, ski pylon and a swim platform with flip-down swim step. Options are plentiful, from cockpit and audio system upgrades to Sea Grass and Sof-Trac floor coverings, a removable cooler, LED interior lighting, a dinette table, air compressor, an electric helm seat and an array of aluminum towers, covers, wake-board racks and shades – even a transom shower. Other convenience features include an electrically powered folding tower with Bimini or rotating sunshade.
