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. 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.
