Summary
An aluminium vessel continued operating despite propeller vibration, later developing a skeg crack and water ingress into the steering room. Crew fitted a cement box, and management required repairs. The flash highlights aluminium’s susceptibility to repetitive stress and urges investigation of changed or increased vibration.
