At 10.50 p.m. on 5th August, 1967, it was learned that two people were cutoff by the tide half a mile east of Splash point, Seaford. The life-boat Kathleen Mary was launched at 11.10 in a moderate westerly breeze and a smooth sea. It was high water. Arrangements were made for a smaller boat to follow when she was free from pilotage duties. The whole area was searched with the smaller boat operating close inshore of the life-boat.

Six parachute flares and the searchlight were used during the search but nothing was found. On the return journey the life-boat took the small boat in tow as her propeller had been fouled. The life-boat returned to her station at 1.20 a.m.
