Why It Matters

The AI‑powered simulator cut development time and boosted crew performance, proving that machine learning can deliver decisive competitive advantages in capital‑intensive sports and beyond.

Key Takeaways

  • AI reinforcement‑learning agent accelerated foil testing tenfold significantly
  • Virtual bot outperformed elite sailors in simulated yacht control
  • Team used AI insights to refine real‑world sailing tactics
  • Quantum Black partnership enabled fully in‑silico design workflow
  • AI‑driven approach helped secure New Zealand’s fourth America’s Cup

Summary

Emirates Team New Zealand partnered with Quantum Black to embed artificial intelligence into the design and training process for its America’s Cup defender. Instead of relying on a physical harness‑based simulator, the team built a fully virtual environment where a reinforcement‑learning agent could control a digital yacht and evaluate foil configurations.

The AI agent accelerated foil testing by more than ten times, and within weeks it began sailing faster than the world‑champion crew. The bot’s performance became a teaching tool, showing sailors optimal tacking maneuvers and foil settings, which they then applied to the real boat, shortening the development cycle dramatically.

Team members highlighted the surprise of elite sailors seeing a newly created algorithm outperform them, quoting, “the most brilliant moves begin with the humility to question what already works.” The collaboration demonstrated that AI can act both as a design accelerator and a skill tutor.

The success helped New Zealand secure its fourth America’s Cup, illustrating how AI‑driven simulation can reshape high‑performance sports and any industry where physical prototyping is costly, offering a template for rapid, data‑rich innovation.

Original Description

Before generative AI was everywhere, Emirates Team New Zealand was already sailing and winning with it.
In 2019, ahead of the 36th America’s Cup, the team partnered with McKinsey and QuantumBlack to build a reinforcement learning agent that could sail inside a virtual simulator — accelerating foil testing nearly 10x.
The result wasn’t just better foil design. The sailors began learning from the agent itself — using it as a tutor to refine maneuvers, improve tacking decisions, and ramp up faster on new configurations.
Some of the most brilliant moves begin with the humility to question what already works.
