Introducing the All-New 470 – Born from Innovation, Built for Victory

After the Tokyo Olympics, a new era of 470 design began. In 2021, a bold vision took shape: to reimagine the 470 class for ultimate performance across all conditions. With over 50 hull variations meticulously evaluated using advanced CFD simulations across 10 different boat speed and attitude combinations, the result is nothing short of revolutionary—a radically optimized hull that blends speed, balance, and control. The new 470 project team has been teamed up with Tsujido Racing as builder, Innovative Composites Centre (ICC) for FRP and materials research and ACT as designer. The sailing tests of the boat have been carried out in cooperation with North Sails Japan.

Olympic-Proven Innovation

The new rudder concept, first used by gold medalists Matthew Belcher & Will Ryan, reappears in this model—further refined and tested. It not only reduces drag but delivers a sharp, responsive feel on the helm with unprecedented grip and flow clarity.

 

What Makes the New 470 Exceptional?

Next-generation hull shape with up to 4% drag reduction, not only in light but also in medium and heavy winds

Effortless control through smart yaw balance and adaptive steering

Innovative rudder design for reduced drag, improved response and grip

High-stiffness, low-CG laminate schedule for superior handling

CNC-milled precision hull and rudder molds for unmatched consistency

Crafted with the expertise of Tsujido Racing, ICC, and ACT

Backed by North Sails Japan in rigorous sailing tests

Designer’s Perspective

“We set out to create a hull that excels across all wind ranges, and a rudder that redefines what’s possible under class rules. The conventional rudder disrupted flow and increased drag. Our solution: shift the rudder’s leading edge below the hull for cleaner, more efficient flow. CFD confirmed it—and Olympic medals proved it.”

This same rudder concept helped Japan's silver-medal team, Okada & Yoshioka, shine at the 2024 Paris Olympics. Now, it’s your turn to experience the edge.

Check out the video comparison of conventional vs. new rudder flow. You'll see the difference—one creates turbulence, the other, smooth precision.
