2026 Rock Marine RM 40

The Rock Marine RM 40 is a 42-foot rigid inflatable boat built on a deep-V hull with triple-step design, delivering high-speed performance paired with offshore capability. Powered by three Mercury gasoline engines, it reaches 78 knots at top speed and cruises comfortably at 60 knots. The boat features joystick control for precise maneuvering and handling.

Below deck, a single cabin provides sleeping accommodations, a galley area, and an enclosed head suitable for overnight trips or extended days on the water. The interior layout prioritizes efficient use of space and durability over unnecessary complexity, supporting both fast day runs and weekend cruising.

The RM 40 is designed as a versatile platform for high-speed coastal cruising, island hopping, or tender support. Construction uses fiberglass and proven methods from Rock Marine's racing heritage, now under the Hull Works group, with each boat hand-built to modern standards for build quality and reliability.
