ROCK 40 Video by e-Ribbing
The ROCK 40 positions itself as a distinctive large inflatable, shaped by the renowned hull expertise of Ocke Mannerfelt. Its design emphasizes offshore capability and refined performance.
A 22-degree deadrise at the transom underlines its offshore intent. The deep-V hull slices through waves, delivering smooth, controlled navigation in demanding sea conditions.
This geometry ensures confident cornering, predictable handling, and strong helm feedback. The focus lies on balanced performance and usability rather than pure top speed.
Honda’s latest outboards complement the boat’s dynamic profile. Their advanced V8 engines deliver smooth power, low noise, and efficient fuel consumption, enhancing overall onboard comfort and control.
