A rebuilt ferry engine caused a catastrophic fire on a UK ferry only five and a half hours after it had been reactivated, an accident report has revealed.

Wightlink's 2,500-gt Wight Sky (built 2008) was approaching Yarmouth on the Isle of Wight on 12 September last year when one of its main propulsion engines broke down, the UK Marine Accident Investigation Branch (MAIB) said.
