The Bay of Naples delivered four races, 18-knot winds, 47-knot bursts of speed and a day of relentless foiling action as Luna Rossa strengthened its grip on the Preliminary Regatta.

Naples finally gave the America’s Cup fleet exactly what it had been waiting for.

Wind.

Speed.

And chaos.

Day Two of the Louis Vuitton 38th America’s Cup Preliminary Regatta turned the Bay of Naples into a high-speed battlefield, with four fleet races completed in conditions that pushed the AC40s — and their crews — hard.

For the Italian fans lining the Lungomare Caracciolo, there was plenty to celebrate.

Luna Rossa 1 remained at the top of the overall standings.

But behind the Italian flagship, the order changed repeatedly throughout the day, while the Women & Youth teams were forced to fight through some of the most demanding racing of the regatta so far.

Luna Rossa starts the day exactly where it wanted

Luna Rossa entered Saturday already leading the standings after Friday’s opening two fleet races.

Peter Burling and Marco Gradoni wasted little time reminding everyone why.

In the opening race of the day, Luna Rossa 1 immediately found the rhythm of the course and sailed away from the fleet. With the northeasterly breeze reaching around 18 knots and at times pushing toward 21, the Italian AC40 was reportedly travelling at more than 47 knots during the bear-away manoeuvre at the windward gate.

It was an extraordinary display of control.

The team read the shifts, found the pressure and kept the boat flying while the fleet behind fought for position.

But Day Two was never going to be that simple.

A penalty, a fightback and another podium

The second race of the day brought Luna Rossa back into the pack.

After receiving a penalty following a protest at the start, Burling and Gradoni had to fight their way back into contention.

They recovered to third at one stage, but a difficult gate decision and a patch of lighter wind ultimately dropped the Italian boat to sixth.

It was a reminder of just how quickly fortunes can change in these boats.

Luna Rossa responded immediately.

In Race 5, the Italian boat was fighting at the front when it was forced to luff sharply to avoid the French La Roche-Posay Racing Team. The manoeuvre cost Luna Rossa its flight, sending the boat to the back of the fleet.

Instead of conceding the race, Burling and Gradoni went to work.

They picked their way through the fleet and eventually recovered to second place.

Then came the final race of the day.

Starting fifth, Luna Rossa climbed back through the field and eventually crossed the line third.

The result was enough to keep the Italian team firmly at the top of the overall standings on 51 points, eight ahead of Emirates Team New Zealand on 43.

Peter Burling admitted afterward that the team had made some major mistakes, but he also pointed to the ability to reset and fight back as one of the day’s positives.

That ability to recover may prove important when the regatta reaches its decisive stage.

Luna Rossa’s Women & Youth team keeps fighting

Alongside the senior boat, Luna Rossa 2 was also dealing with the difficult conditions.

Margherita Porro and Massimiliano Antoniazzi shared the helming duties, with Giovanni Santi and Maria Vittoria Marchesini trimming.

The Women & Youth boat opened Saturday with a strong fourth-place finish.

It followed that with fifth before a difficult eighth in Race 5 after falling off the foils on the final upwind leg.

The team recovered to finish fifth in the final race.

That left Luna Rossa’s Women & Youth boat on 35 points and fourth overall, while remaining at the top of the dedicated Women & Youth standings.

Porro described the racing as extremely tight and acknowledged that the team is still learning how to connect all the elements of its performance.

“We are a new team,” she said, while pointing to good starts and the speed of the boat as positives from the day.

And Athena Pathway?

For those following the British Women & Youth programme, there is a new name on the scoreboard.

Athena Pathway is now Cobham-Ultra GB2.

The programme arrived in Naples as one of the teams developing the next generation of British America’s Cup sailors, and Saturday provided an unforgiving test.

The British boat struggled to maintain consistent positions in the fleet and was among the teams receiving penalties during the day’s racing.

It was a difficult contrast to Friday, when Cobham-Ultra GB2 had shown flashes of genuine pace.

The challenge on Saturday was not simply speed.

It was putting everything together — starts, positioning, foiling control, tactics and the ability to remain clean in a fleet where nine AC40s can converge on the same mark at extraordinary speed.

With the fleet compressed, one mistake could send a boat several places down the order.

That is exactly the sort of experience the Women & Youth programme exists to provide.

The French put on a show

While Luna Rossa controlled the overall standings, La Roche-Posay Racing Team produced perhaps the most dramatic performance of the afternoon.

The French team won Race 4 and then appeared to have Race 5 completely under control.

They had stretched their advantage to roughly 300 metres and looked destined for another victory.

Then came the final gybe.

A strong pulse of wind lifted the boat dangerously high on its foils. The boat ventilated, lurched into the wind and eventually capsized.

The fleet came screaming past at more than 40 knots.

It was spectacular — and a brutal reminder of how little margin exists between extraordinary speed and losing control of an AC40.

The French response was impressive.

They came back in Race 6 and won again.

New Zealand joins the fight

Emirates Team New Zealand also had a rollercoaster day.

After a difficult opening race, the defending America’s Cup champions recovered strongly, taking second in Race 4 and later winning Race 5.

They finished the day second overall with 43 points, just eight behind Luna Rossa.

Tudor Team Alinghi sits third on 38, followed by Luna Rossa Women & Youth on 35.

The importance of that second-place position cannot be overstated within the format.

After the two remaining fleet races on Sunday, the top two teams will advance to a winner-takes-all Match Race final.

So Luna Rossa is not simply leading.

It is already putting itself in position for the final showdown.

Naples has delivered

There is something fitting about the America’s Cup returning to Naples.

The city provides the backdrop, but just offshore the racing is increasingly resembling controlled chaos.

The boats are travelling at extraordinary speeds.

The wind is shifting.

Penalties are changing positions.

Teams are falling off their foils.

And the difference between first and the middle of the fleet can disappear in a matter of seconds.

For Luna Rossa, however, Saturday was ultimately about resilience.

A win.

A sixth.

A second.

A third.

Four races that included mistakes, penalties, lost positions and recoveries — yet the Italian team still finished the day at the top.

For Luna Rossa’s Women & Youth team, it was a tougher day but another valuable step forward.

And for Cobham-Ultra GB2 — the programme many fans still know as Athena Pathway — Naples continues to provide exactly the kind of high-pressure racing experience that will shape Britain’s next generation of America’s Cup sailors.

Sunday is where it becomes serious.

Two fleet races remain.

Then comes the Match Race.

One race.

Two boats.

Winner takes the Naples Preliminary Regatta.

And after what Naples delivered on Saturday, there is little reason to expect the final day to be anything less than spectacular.
