Shoreham Harbour, Sussex - At 7.55 p.m. on 26th April, 1966, the coastguard told the honorary secretary that a speedboat had capsized one and a half miles east-south-east of Shoreham harbour entrance. The life-boat Dorothy and Philip Constant was launched at 8.3 in a moderate east-south-easterly wind and a choppy sea. It was one hour before low water. The life-boat reached the speedboat Sheila Ann at 8.20 and found three skin divers clinging to the upturned hull.

These were immediately taken on board the life-boat, with the speedboat taken in tow. The life-boat arrived at her station at 9.30..
