READ NOW‘We had four confirmed sightings of flares from people in the Quinns Rocks area.’
Water Police found the 6m fibreglass boat about 11.10pm and asked the sea rescue to pick up the vessel and men on board.
‘We picked them up off the police boat,’ Mr Howell said.
The sea rescue volunteers, who had travelled from Hillarys Boat Harbour in Green 1, took the men and towed their boat back to Mindarie.
‘It was a good result,’ Mr Howell said. ‘The community did the right thing by calling us and the police when they saw the flares.
‘And the men did the right thing by telling somebody where they were going and when they’d be back ” that makes a big difference.’
