Tasmania Police have concerns for the welfare of Mark David Moylan.

Mr Moylan was last seen between 8pm and 9pm on Saturday 25th January 2014, rowing a 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.

He is described as being 170cm tall, of slim build with a tanned complexion and short brown wavy hair. He is 42 years of age.

Police have subsequently located Mr Moylan’s aluminium dinghy washed up on the shore approximately 4 kilometres north of his last known location. However Mr Moylan has not been seen since.

Police are asking any member of the public who knows the whereabouts of Mark David Moylan to contact Beaconsfield Police Station on (03) 6383 2002 or Tasmania Police on 131 444.
