A former Royal Navy officer is set to face a court martial following the catastrophic sinking of a New Zealand naval vessel after it struck a reef, with the crew failing to disengage the autopilot system. Commander Yvonne Gray, who served nearly two decades in the Royal Navy, was in command of the HMNZS Manawanui when the incident occurred off the coast of Samoa on October 5, 2024.
Charges and Allegations in the Court Martial
Commander Gray faces serious charges, including being absent from the ship's bridge while within a nautical mile of a reef and failing to adequately manage risks during hydrographic work in uncharted waters near reefs. If convicted, she could receive a maximum sentence of two years' imprisonment. Additionally, Lieutenant Commander Matthew Gajzago and a third individual will also be court-martialed in connection with the sinking.
Details of the Shipwreck Incident
The HMNZS Manawanui, a specialist dive and hydrographic vessel for the Royal New Zealand Navy, was conducting a reef survey near the Samoan island of Upolu when it ran aground. The vessel subsequently caught fire and capsized, leading to its total loss. A military court of inquiry attributed the sinking to human error, specifically noting that senior crew members did not notice the autopilot was engaged as they struggled to control a thruster and prevent the grounding.
Despite the perilous conditions, all 75 crew members evacuated the ship using lifeboats and were rescued, even as strong currents and winds pushed them toward the reefs. According to the Samoa Fire and Emergency Services Authority, no lives were lost and no one was 'heavily injured,' though two crew members were hospitalized—one with a dislocated shoulder and the other with a back injury. Another twelve suffered minor cuts and soreness.
Background of Commander Yvonne Gray
Originally from Harrogate in North Yorkshire, Commander Gray relocated to New Zealand with her wife in 2012 before joining the country's navy. She assumed command of the Manawanui in December 2022, marking her first such leadership role. Her barrister, Todd Simmonds, has stated that Gray has 'endured a lot of unjustified criticism' over the ship's sinking and that she denies all charges.
Financial and Historical Significance of the Vessel
The 85-meter ship, originally built in 2003 as the MV Edda Fonn, was purchased by New Zealand from Norwegian company Østensjø Rederi for NZ$103 million (approximately £45.6 million), including costs for modification and introduction. It was delivered in May 2019 and represented a significant investment for the Kiwi government. This incident marks the first loss of a New Zealand naval ship since the Second World War and the first in peacetime, with the wreckage still resting on the sea floor near Upolu, Samoa.
