Three people were rescued after their yacht struck Bass Island off Port Kembla on Sunday afternoon.
Marine Rescue Port Kembla and Port Kembla Water Police received a mayday emergency call about 1pm.
Marine Rescue Illawarra regional controller Bruce Mitchell said the trio was found safe and still onboard the yacht.
Mr Mitchell said after examining the yacht, rescue teams decided it could be pulled free safely and attached a line to it from Marine Rescue vessel Port Kembla 30.
It was then carefully pulled off the rocks and towed to safety in Wollongong Harbour.
‘‘The mayday was received by our radio base at Hill 60. Port Kembla 30 was in Port Kembla Harbour and responded within minutes of the call being received,” Mr Mitchell said.
“Four volunteers from Marine Rescue Port Kembla were on board our vessel including skipper Bruce Williamson and unit commander Peter Purnell.’’
Mr Mitchell said there was a strong wind warning in place for the Illawarra coast on Sunday afternoon.
He urged boaters to wear life jackets and log on with their local Marine Rescue NSW radio base.
