At 11.10 a.m. on i6th April, 1967, a small boat which had left Shoebury for Wallersay bay, was reported overdue.

The life-boat Greater London II (Civil Service No. 30) was launched at 11.20 in a moderate northerly wind and a choppy sea. It was five hours after high water.

She proceeded towards the Maplin Sands and Whittaker Channel. A fishing boat then informed her that a small yacht was in difficulties on the Whittaker Spit. The life-boat found the yacht Zeus with two men on board. The yacht had lost her rudder and was taking in water. After a line had been secured to the Zeus, the life-boat took her in tow and proceeded towards Wallersay. Information was then received that the original casualty was aground but did not require assistance.

The life-boat moored the yacht at Wallersay and returned to her station, arriving at 8 p.m..
