Caister, Norfolk - At 4.45 p.m. on 23rd June, 1966, the station mechanic noticed a vessel dragging her anchors in Yarmouth Roads. She was put under observation and at 5.40 she hoisted a distress signal. The life-boat The Royal Thames was launched at 6 o'clock in a moderate south westerly wind and a slight sea. It was almost low water. When she reached the motor vessel Regency, the life-boat found that her engines had broken down and she required a tug.

The life-boat stood by the Regency until a tug, whose help had been requested through the Gorleston coastguard, arrived and then returned to her station, arriving at 8 o'clock..
