Marine Rescue NSW boat Middle Harbour 30 has towed a capsized vessel to a mooring in Vaucluse after a dive boat overturned near Hornby Lighthouse over the weekend.
Emergency Services responded to a MAYDAY call around 2.20pm Sunday.
Marine Area Command rescued nine divers and the master from the water.
NSW Police said the group was taken to Rose Bay Wharf and assessed by NSW Ambulance paramedics with no injuries recorded.
“The master, a 59-year-old man, returned a negative breath test,” Police said.
MH 30 delivered the overturned vessel to a mooring in Vaucluse just after 4.40pm.
Marine Rescue NSW boat Port Jackson 20 assisted with the collection of items from the water where the vessel capsized and delivered the salvaged property to the Marine Area Command headquarters in Balmain.
Inquiries into the incident are continuing.
