POLICE are concerned for the welfare of a man who was last seen in a dinghy on the Tamar River.
Mark David Moylan, 42, was last seen between 8 and 9pm on Saturday, January 25, rowing the small aluminium dinghy on the Tamar River from the Gravelly Beach Marina to his vessel, which is moored in the bay directly outside the Gravelly Beach Marina.

Mr Moylan has not been seen since.
He is described as being 170 centimetres tall, of slim build, with a tanned complexion and short brown wavy hair.
Police urge anyone who knows the whereabouts of Mr Moylan to call Beaconsfield Police Station on 6383 2002 or Tasmania Police on 131 444.
