2024 Cobalt R4 Surf

The 2024 Cobalt R4 Surf is a 24-foot fiberglass ski and wake boat built for surfing. Powered by a single 350-horsepower Volvo gasoline engine, it combines a low profile hull design that sits closer to the water with Cobalt's Custom Wave Technology surf system. The boat features multiple hard ballast tanks integrated into a redesigned hull, along with Surf Gate technology, allowing precise wave shaping and adjustment for different surfing conditions.

At 8.5 feet in beam, the R4 Surf's compact profile makes both trailering and storage practical. The forward-facing Volvo powertrain and purpose-built surf hull work together to generate and maintain consistent waves for behind-the-boat riding.
