Exterior

The R4 Surf has one of the lowest profiles of the R Series—putting you closer to the water and making trailering and storing easier. Featuring Cobalt’s Custom Wave Technology surf system with multiple hard ballast tanks, the Volvo FWD powertrain, and a specifically redesigned surf hull that integrates with our best-in-class Surf Gate™ technology, shape your perfect wave every time.
Swim Step

Popular and envied, our patented Swim Step lowers below the water line for easy access in and out of the water, is great for lounging, pets, and stows flush within the swim platform surface.

 

Surf Graphics

Enjoy hull-side color patterns special to Surf models, with upper-hull color areas that create unique looks with space for additional colors in the scheme—plus chrome Surf badging accents

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.

Cobalt Surf System

With Cobalt’s revolutionary surf system, Custom Wave Technology powered by Volvo Penta, you get the combination of Malibu Surf Gate™ with an explicitly designed surf hull, the Volvo FWD powertrain, and multiple hard ballast tanks that can have as much as 2,350 pounds of ballast. Plus, select your rider profile and the system will automatically configure the boat per the pre-saved profile setting. The result is a best-in-class wave that will even compete with some competition towboats.

What Makes The
Cobalt Surf System

volvo penta FWD

Volvo Penta FWD

Cobalt’s Custom Wave Technology begins with the Volvo Penta FWD powertrain, uniquely engineered with forward-facing Duoprops positioned well under the boat for added safety. The counter-rotating props pull the boat through the water rather than pushing it, resulting in better bite, acceleration, and speed in a more efficient, smooth way, increasing fuel economy. Because the Forward Drive is under the boat, there’s less noise and exhaust, meaning more comfort. The adjustment of drive trim is also one of the single biggest factors to quickly adjusting a wave to your liking.

Surf Controls

Driving with the Cobalt Custom Wave Technology couldn’t be easier. Just turn on Speed control. This is the “ON and OFF” for your surf system. Select your rider profile and the system will automatically configure the boat per the pre-saved profile setting—ballast, drive trim, speed, surf left or surf right. Cobalt is set up with two starter profiles: Mellow and Steep. These will give you a starting point for setting up your wave. Then when the surfer is ready, put the throttle down and the boat will automatically adjust to the profile surf settings and speed. With the touch of the surf button on the dual Garmin Glass Cockpit touchscreen, the driver can switch the surf wave from right to left, even while underway.
surf gate

Surf Gate

Surf Gate™ is the dominant surf technology in the industry—and for good reason. Using high-speed hydraulic actuators, Surf Gate™ creates an endless surfable wave on either side of the boat. Just ask the pros—they’ll tell you Surf Gate™ creates the longest, highest, cleanest wave with the best push out there. Get back as far as you want or as close as you want. While several sterndrive brands have models outfitted with ballast and some form of surf mechanism, Cobalt is the only brand that has integrated the best-in-class Surf Gate™ technology with a specifically designed surf hull form and Volvo FWD powertrain to generate the world-class wave that will absolutely rival some of the best competition towboats on the market.
surf ballast

Surf Ballast

Your Cobalt surf boat has multiple hard ballast tanks and can have as much as 2,350 pounds of ballast. The hard ballast tanks allow you to better scale the wake and wave for all ages and ability levels. Remember that additional weight in the boat doesn’t always translate to a good surf wave. The general rule for surfing in a Cobalt is to fill all the ballast tanks in accordance with your boat loading—such as if you have two people in the boat you can fill the ballast all the way up. But if you have 10 people in the boat, perhaps you only need the ballast tanks a quarter full.

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.
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.

Interior Feature

Cobalt + Garmin

The Cobalt Glass Cockpit System is the premier multi-display solution for total helm control. The Garmin interface is fully integrated with the most pivotal handling and safety information from your Cobalt powertrain. The result is the ultimate boating experience now available with larger screens on select Cobalt models.
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.
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.

Interior

Inside the R4 Surf, discover where state-of-the-art becomes fine art. A family sized sport runabout that incorporates sleek lines, crisp handling from the dual Garmin Glass Cockpit touchscreens, and a range of options, the uniquely refined interior complements its unsurpassed watersports capability.
Surf Control System

Select a rider profile and the system will automatically configure the boat per the pre-saved setting—ballast, drive trim, speed, surf left or surf right—all from the cockpit touchscreen.

Interior Styling

Find additional accent vinyl colors and stitching coordinated with the exterior hull. Plus, honeycomb stitching in the side-panel vinyl and honeycomb-embossed Sof-Trac floor mats.

LED Accent Lighting

Create a rich nighttime ambiance in the cockpit and bow areas with indirect lighting hidden in interior upholstery side panels that feature RGB selectable color and LED low-power consumption.
