At 11.4 p.m. on 4th August, 1966, a vessel was seen flashing a light south of the harbour entrance. There was a fresh north westerly breeze with a moderate sea. The life-boat Kathleen Mary launched at 11.30 at low water and proceeded to the position given. She found the Dutch trawler Guus with engine trouble and uncertain of her position. The life-boat bowman boarded the trawler which then proceeded into Newhaven harbour escorted by the lifeboat.

The life-boat arrived back at her station at 12.25 a.m. on 5th August..
