Police are appealing for a witness to come forward following the death of a man after his boat capsized in Kalimna in March.
Emergency services were called to Reeves Channel off Princes Hwy after passing boats spotted two men in trouble just before 10am on 25 March.
A 55-year-old man, who was visiting Australia from Vietnam, was pulled from the water unconscious.
Despite the best efforts of good Samaritans, he died at the scene.
The second man, a 61-year-old from New South Wales, was treated by paramedics on scene and did not sustain any injuries.

He is perceived to be of Caucasian appearance and aged in his 50s.
