Humber, Yorkshire - At 7.28 p.m.

on 18th February, 1968, the coastguard informed the coxswain that a motor boat was in difficulties off Cleethorpes pier. The life-boat Edward and Isabella Irwin, on temporary duty at the station, was launched at 7.35. It was one hour before high water. Patches of dense fog restricted visibility and the lifeboat did not locate the casualty until nine o'clock. She was found about a half mile north of Cleethorpes pier drifting out of the river into the main channel on the ebb tide. Her engine had broken down. There was a man and a woman on board. The latter was taken aboard the life-boat and the motor boat was taken in tow to Grimsby. The life-boat returned to her station at eleven o'clock. A helicopter also participated in this operation..
