Report highlights causes of loss of prawn trawler off northwestern Scotland

The MAIB investigation found that the skipper, who was alone in the wheelhouse at the time of the accident, had fallen asleep. He was fatigued due to working through the night before the accident to carry out repairs on board and a sleep debt accumulated in the days and weeks before the accident.

The risks associated with lone navigational watchkeeping had been identified in onboard risk assessments, but the control measures had not been implemented, according to the MAIB.
