The Ultimate Luxury Performance Statement

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

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.

Interior

Strikingly redesigned, the R8 Surf features a higher profile with more freeboard, a roomy, expansive interior with both bow and cockpit larger fore to aft, all providing extra comfort for passengers and plenty of room for everything they need for a day on the water.

Aft-Facing Rumble Seat

Adjusts to 2 positions to provide the flexibility of facing forward or aft. Stainless-steel handle provides added security in rough waters and is supported by a heavy-duty steel hinge mechanism.

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

Features May Include:

• Full Color Deck
  • Introducing an unprecedented level of personalization to Cobalt's signature Surf Series. For the first time in Cobalt history, the R4 Surf, R6 Surf, and R8 Surf models now offer complete creative freedom with your choice of deck coloration.

• Monsoon Engines
  • Thanks to a close partnership with GM Marine and following the strictest industry standards, Monsoon engines are produced in a state-of-the-art engine facility in Tennessee. Technology is the key behind our new ultra-clean engines. It all starts with direct injection, which bypasses the air intake manifold and injects fuel directly into the combustion chamber, making for a cleaner, more controlled and complete burn resulting in improved fuel economy.

  • Harness the dependability, durability, and capability of Garmin at your helm with our feature rich, high-resolution glass cockpit. Here you'll find advanced navigation, networking and instrumentation technology combine with an intuitive interface to meet the needs of any captain.

Experience unparalleled coverage and detail with built-in Garmin Navionics+™ integrated coastal and inland mapping. With SmartMode™ everything is designed to give you quick, one-touch access to the information you need.
    • Saltwater or fresh — no matter where you take to the water, you can trust Garmin marine technology to give you an unsurpassed level of confidence at the helm.
• Rotating SunShade
  • No need to take down your sunshade with the Rotating Sunshade. Shown on the Prisma 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.
• 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.
• 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.
• Fender Clip Package
  • 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.

Cobalt Surf System

Cobalt's Surf Series seamlessly integrates Surf Gate™ with a custom-designed surf hull, all powered by Volvo Penta. Nearly all boats in the series employ traditional hard ballast tanks for wave customization. The R31, R33 and  R35 Surf models adopt a streamlined design without ballast tanks. This tailored approach ensures agility and simplicity, redefining expectations for surfing enthusiasts across the entire Surf Series.

What Makes The Cobalt Surf System

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 automatically configures 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 automatically adjusts to the profile surf settings and speed. With a 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.
