Exterior
The R4 has the lowest profile of the R Series, not only putting you closer to the water, but also making it easier for trailering and storing. Still, the deep-V hull is long and lean for a commanding presence on the water and standout ride Cobalt is known for.

Our patented Flip Down Swim Step makes both lounging on the back of the boat and re-entry easy and enjoyable. For even more luxury and ease of use, you can opt for the new Powered Swim Step, which deploys in and out of the water with push-button convenience from the stern

Find a polished stainless steel top surface cap to windshield frames and enjoy the brightwork look the windshield possesses—all crafted to reflect heat in the sun and be cooler to the touch.

The wide engine hatch opening allows for easy access, easy maintenance, and storage space access—and the easy-lift hatch is gasket sealed when closed to reduce noise in the cockpit.
Features & Innovations
Interior
With a thoughtfully crafted interior environment and painstaking attention to detail, the R4 elevates the experience of day-boating on the water with your family and friends to a new, luxurious level.

Adjustable to 3 positions—face forward, face aft, and full down to extend sunpad space—with stainless-steel handle for added security in rough waters and a heavy-duty steel hinge mechanism.

Create more lounge area in the bow and transom seating with Cobalt factory-made filler cushions. As with all Cobalt seat cushions, you get total composite seat-base construction.

Experience maximized seating and modern design touches like contrasting color combinations, quilted upholstery, and Fresco Chil Vinyl on dark interiors to keep surface temperatures cooler.
