Fusion Marine Boatbuilders (FMB) are proud to unveil their custom-built, full-carbon 10.5m race yacht, designed by Rob Shaw, from the drawings of owner Scott Fyfe. On its debut day of sailing, it’s already proving itself to be a powerhouse, achieving speeds over 20 knots. Every detail of this advanced, high-performance yacht has been meticulously engineered, from its complex winged water ballast system to the innovative lifting keel and rudder. Inspired by the design of a world-class supercar, the cabin top offers an unmistakable touch of luxury and speed. This yacht is truly in a league of its own, offering unmatched performance and cutting-edge design. Sneak preview below. More photos to come.
