The 1965 Breakdown Incident.

On November 1, 1965, while returning home to New Zealand from a deployment in the Far East, the cruiser suffered a catastrophic total engine failure in the Coral Sea, south of Guadalcanal.The Cause: Severe salt-water contamination entered the ship’s condenser feed-water—a condition colloquially known by the crew as “condenseritis”. This heavily damaged the aft boilers and evaporators, forcing engineers to completely shut down propulsion.The Rescue: Left drifting in the open ocean, the ship received emergency assistance when the Royal Navy survey vessel HMS Dampier arrived to tow her out of immediate danger. This photograph was captured by a responding RNZAF flying boat dropped in to deliver mail and assess the situation. Shortly after, the ocean-going Australian tug Carlock hooked onto Royalist on November 7 to begin the long tow home.The Aftermath: By November 12, the ship’s engineers managed to complete heroic patchwork repairs at sea, allowing Royalist to drop the tow lines and limp into Waitemata Harbour under her own severely reduced power. Because the damage to her machinery was too severe to justify repairs, this breakdown ended her active career five months early. She spent her remaining days moored as a stationary training ship at Auckland before decommissioning permanently in June 1966
