Leyton x SailGP

Where Data Meets Speed

Harnessing the power of high-frequency data to drive a net-zero future.

For over two decades, Leyton has been a catalyst for innovation. Our alliance with SailGP—the world’s most sustainable and technologically advanced racing league—is more than a partnership; it is a shared laboratory for the future. By integrating our deep expertise in R&D tax incentives and energy transition with the high-frequency data streams of 50-knot F50 catamarans, we are proving that ecological responsibility is the ultimate driver of economic efficiency.

Together, we are not just racing; we are pioneering. From optimizing foil aerodynamics using advanced carbon-tracking algorithms to implementing circular economy principles across the league’s global operations, our work ensures that every mile sailed contributes to a net-zero horizon. This is the story of how data-driven consulting meets the raw, unyielding power of the ocean to create a legacy that outlasts the race.
