A Dutch Safety Board accident investigation into the grounding and eventual constructive total loss of a general cargoship off the Greek island of Lesbos has raised serious questions about the safety of electronic navigation systems.

The 4,000-gt Nova Cura (built 1999) grounded in the shallow Lamna Reef in the Mytilini Strait, with the ship’s electronic chart display information system (ECDIS) indicating the depth should have been 112 metres.
