Was this the most expensive crash at the Monaco Grand Prix? Out-of-control speedboat smashes into dinghy and superyacht full of partying guests at Monte Carlo harbour's 'billionaire's row'

This is the moment a speedboat smashed into two other vessels docked along Monaco's famous 'billionaire's row' during one of the most historic events on the Formula 1 calendar.

Video circulating on social media shows how the unmanned powerboat zoomed through the Monte Carlo Harbour, before veering in between a small dinghy and a superyacht full of partygoers.

The boat, sending debris flying through the air, came to a miraculous stop on the metal dock after nearly colliding with two passers-by.

Witnesses say that no one was injured during the collision, Fox Sports reported, but several boats were left damaged.

It is rumoured that for the past week American F1 driver Logan Sargeant and his family had been living on the superyacht that was struck in the incident.

Firemen and emergency crews responded to dock after the collision last weekend, witnesses have detailed on social media.

Authorities reportedly checked on the pedestrians who narrowly escaped and towed the out-of-control boat away from the scene.

It is suspected that the operator of the speedboat will face hefty fines for damages from the incident, which occurred one of the most exclusive locations in the world. 

The Monte Carlo Harbour is often referred to as 'billionaires' playground' as most of the yachts docked there are owned by multi-billionaires.

Video of the incident has since gone viral, with some speculating it was the most expensive crash to occur at the Monaco Grand Prix.

'Crazy crash in Monaco today,' one person wrote, sharing the footage on Instagram. 'Nobody was on board or hurt. VERY lucky!!! Properly wearing an engine cut off switch would have prevented this! 

'Please wear them. Consider buying the wireless options if you don't want to wear the lanyard.'

Another posted the video on X, writing: 'Could this be the most expensive crash at @Monaco this weekend?'

F1 commentator Will Buxton even joked about the incident, saying: 'Mate, you can't park there.'
