At 9.38 a.m. on 22nd March, 1967, news was received that the motor fishing vessel Madame Sands was proceeding to Bridlington Bay with a mine on board. The life-boat crew stood by until 10.42 when a message was received from the coastguard that in view of the proximity of the Madame Sands to the harbour it was advisable that those on board be taken off. The life-boat Tillie Morrison, Sheffield II was launched at 11.10 in a light west north westerly wind and a slight sea. It was four hours before high water.

At the request of the coastguard the Madame Sands moved two miles out to sea escorted by the life-boat. Her crew were then taken off by the life-boat and landed at Bridlington. Arrangements were then made for the crew to re-assemble at 3.30 to embark the Royal Naval Mine Unit. At 3.20 the coastguard again requested the assistance of the life-boat to investigate an unidentified object floating two hundred yards off the east pier. On identifying the object as a derelict wooden cart the life-boat returned to harbour. At 6.10, having confirmed that the object on board the Madame Sands was a mine, the life-boat crew stood by with the mine disposal unit, finally returning to her station at 11 o'clock..
