Western Australia's largest sail-training vessel, the STS Leeuwin II, has been crushed by a container ship at Fremantle Port.
The incident happened around 6am on Friday morning.
Two people, a man in his 20s and a man in his 60s, were onboard the Leeuwin at the time.
They were both taken to Fiona Stanley Hospital with non-life-threatening injuries.
Investigations are underway into what caused the container ship to collide with the Leeuwin, but there are reports bad weather may have been a factor.
The Leeuwin II was launched in 1986 and is used to train young sailors.

The container ship remains at anchor next to the Leeuwin. PIC: Facebook
