He is in charge of the deck but is also a qualified skipper.
Mrs Roberts said the net was full of fish when it also pulled up the plane. The fish had to be thrown back into the sea and the net was handed over to police.
A new net was fitted on Thursday night and the boat is now back on fishing duty.
The find brought closure to the family of pilot Daroish Kraidy, who had been missing since March 25.
Mr Kraidy had represented New Zealand and come second at the Precision Flying World Championships. He had flown out of Ardmore Airport at 11.30am on March 25 and the plane disappeared from radar detection shortly after.
A detailed inspection of the wreckage and its contents was carried out yesterday by a police disaster victim identification expert and Civil Aviation Authority personnel, police said.
