Bigger Cook Strait ferries risk collision and grounding: report

A report into maritime safety in Tory Channel finds KiwiRail's proposed bigger interisland ferries carry a heightened risk of grounding and collision which could result in catastrophic loss of life or an oil spill. Kiwirail plans to have two new ships in operation by 2024, which would be nearly 40 metres longer and at least five metres wider than the current ships. The Marlborough District Council commissioned an assessment of navigational safety and risk in Tory Channel - the narrow waterway used by ferry operators between Wellington and Picton. That report identifies 67 risks, including grounding, collision, limited tug availablity and the need for better aids to navigation. However KiwiRail's own risk report finds there is no additional risk in Tory Channel associated with larger ferries. Kathryn speaks with Marlborough Harbourmaster, Luke Grogan, who is leading a risk assessment group considering the issues. Also with Paul Keating, chairperson of residents' group Guardians of the Sounds.
