It's a question that puzzles newcomers to the sport. These F50 catamarans tear around courses at 50 knots, yet somehow it's the opening sprint leg – sailed at 90 degrees to the wind – that causes the most chaos. Stranger still, this is exactly the angle we teach complete beginners. So why do the world's best sailors struggle with what should be the simplest task?

In this video, Mozzy breaks down the physics behind the sprint leg's fearsome reputation. We look at what's happening in the air, what's going on beneath the surface, and why the control systems caught between those two forces can reach their breaking point in seconds. There's a reason elite sailors call this the death zone – and it has everything to do with a runaway feedback loop that even the best crews can't always contain.

The sprint leg exposes a fundamental truth about foiling catamarans: the faster they go, the more fuel they extract from the wind. It's a positive cycle that sounds brilliant until you realise there's no off switch. When displacement boats accelerate, the hull creates drag. When an F50 accelerates, the throttle just opens wider.

And the incidents are stacking up. Italy, New Zealand, Brazil – all victims of what happens when the control systems hit their limits and the boat stops responding. @SailGP has implemented safeguards to prevent catastrophic structural failure, but those same limits create their own problems. Should the format change? Are split fleets necessary? These are questions the league will have to answer.
