The German skipper of a yacht missing with two female crew on board set sail without telling anyone where he was going and ignored maritime safety instructions.
Police now hold grave fears for the trio on board the Munetra which was last heard from on April 16 when it made radio contact in rough weather off Centre Island.
The last person to speak to the 33-year-old skipper, Bluff Marine Radio operator Meri Leask, said the 7.5m craft was in "unsuitable waters" at the time.
Prospects of finding the vessel and those on board were "grim", she said.
"It didn't matter what you said. He just had his own way of doing things and refused to listen to any other advice."
