Search ongoing for missing Tas boat duo

Almost a week after a group of four mates set off for a fishing trip southeast of Hobart, police and volunteers are still looking for two of their bodies.

Crews on Saturday will return to patches of sea adjacent to the boat's launch spot at Cremorne, searching for any sign of the 4.9-metre fibreglass runabout or two men missing, presumed dead.

They are a 26-year-old Hobart man and a New Zealander aged 35.

The alarm was raised on Sunday when the foursome failed to return as planned after a few hours.

The next day the bodies of Hobart men Magnus Julian Ritter, 34, and Luke William Davies, 32, were recovered.
