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.
Swim Step

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

Stainless Steel Windshield Trim

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.

Engine Access

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

Step & Platform Innovation

PATENT PENDING E-STEP ELECTRICALLY POWERED SWIM STEP

Cobalt’s already easy-to-use Swim Step just got easier. With the push of a button, the step folds into the water or returns from the water into the stowed position—all from the convenience of the aft sun pad. Designed to be sleek, simple, and effortless, the e-Step deployment has a near-silent actuation, making it the quietest actuated step on the market.

Interior Innovation

Fresco Chil Vinyl

Finally, no more hot seats on darker colored vinyl while you’re out enjoying a full day of fun on the water. This anti-bacterial, anti-fungal, mildew-resistant, and sulfide stain-resistant fabric technology keeps your vinyl a full 15-20 degrees cooler than traditional vinyl even when it’s out in the sun.
Exterior Innovation

Arch With Rotating SunShade

No need to take down your sunshade with the Arch with Rotating Sunshade. Built on our aluminum folding arch, the canvas remains up when the arch is folded down to lower positions, and the sunshade has a rigid frame for tight canvas fit and articulates as the arch is folded down, remaining flat. Gas assist cylinder or full electric actuation options make it easily operable for one person.
Step & Platform Innovation

SOF-TRAC POSITIVE TRACTION MAT

Dress up your swim platform with the Sof-Trac Positive Traction Mat. Gentle on swimsuits and wakeboards, you’ll maintain traction even when wet. Dealer-installed kits are available for most current models with or without the Swim Step.

Exterior Feature

Fender Clip Package

The Cobalt stainless-steel fender clips are a quick mount system installed in the deck at the perfect fender position, so the lines are always set to optimum length. When docking, simply insert the pin into the fitting and you’re done.

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.
Aft Backrest

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.

Bow Filler Cushion

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.

Interior Styling

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.
