A Rubber mattress
Brighton, Sussex. At 4.7 p.m. on 8th July, 1965, the life-guard for the east section of the beach told the beach superintendent's office that a boy on a rubber mattress was drifting seawards off Black Rock swimming pool and signalling for help. At 4.10 the IRB launched in a north-westerly breeze and slight sea.
The boy was taken to the IRB station, which was reached at 4.25, and transferred to the care of the St. John Ambulance first aid post..
