SailGP said in a statement that the weather had caused "significant damage" to at least one of the boats in competition.

After being whisked into the air, the boat was ripped apart and crashed into a tent, sending people running.

There was also damage to infrastructure at Barangaroo Wharf.

Safework NSW has been advised.

Fire and Rescue NSW said they were in attendance with four fire trucks on Barton St "to a temporary building that has been damaged by the weather".

"Evacuations taking place with numerous minor injuries," they said on social media.

The second day of the event has been cancelled.

SailGP indicated the scale of the damage could be bad enough for future international events to be postponed.

New Zealand is the next event on the calendar, with the competition scheduled there for March 18-19.
