The 2026 Cobalt R31 is where luxury, performance, and versatility all come together in one seriously dialed-in package. With twin V8 power, a Kevlar-reinforced hull, and a layout built for entertaining or extended days on the water, this R31 delivers the kind of ride and refinement Cobalt is known for—just on a bigger, more capable scale. This particular build is heavily optioned and ready to impress at the dock or running wide open.
This R31 checks all the boxes for someone wanting big-boat capability without stepping into a full cruiser. Whether you’re tying up with friends, running across the lake, or spending the whole day onboard with the family, it delivers a premium experience from bow to stern.
