Special prayers have been said at a church service for two boys swept off cliffs in Dorset by a wave.
Charlie Morrell and Matthew Myburgh were both local boys
Matthew Myburgh, 16, and Charlie Morrell, 15, disappeared into the sea at Lulworth Cove, on Thursday.
A special service was held at the Holy Trinity Church in West Lulworth on Sunday afternoon.
A coastguard spokesman said clothing, believed to belong to one of the boys, had also been found along the shoreline of the cove on Sunday.
Specialist dive teams from Avon and Somerset Police were forced to abandon a recovery operation on Sunday because of deteriorating weather conditions.
On Saturday the search was downgraded from rescue to search and recovery, and coastguards said it was unlikely the boys would be found alive.
The missing boys were with a third teenager who raised the alarm when he saw his friends washed into the sea.
Mark Rodaway, senior coastguard officer for the south of England, said: "Everything we had available to us has been brought to bear in this particularly awful incident.
"Overall we've had in excess of 100 people searching for the two boys.
"Given the awful weather conditions that both the boys and the rescue workers were facing, with the temperatures and the time we are now looking at, a successful outcome looks unlikely.
"We have covered certain areas. We are certain the boys are not there."
About 100 people have been involved in the search
Mr Rodaway said a trainer found on Saturday had been identified as belonging to Matthew.
Ch Insp Nick Maton, of Dorset Police, said if the boys were not found over the weekend by underwater search units from Avon and Somerset, a private company specialising in underwater searches would be brought in on Monday.
Rescuers had scoured a 10-mile section of coast from Warbarrow Bay to Bat's Head.
The boys, from the local area, were fishing when they went missing in heavy rain and strong winds, where waves up to 9ft high battered the cove.
Ch Insp Maton said: "The storm was exceptional, people are already saying it was one of the worst storms in living memory."
Mr Rodaway said that with the water temperature at 14C, a person could survive for about three hours without wearing survival equipment.
Richard Holman, head teacher of The Purbeck School in Wareham, where the boys were pupils, said: "We are obviously concerned for their safety and well-being. I hope they are found alive and well."
Ch Insp Nick Maton said the youngsters' families had been waiting in a nearby hotel for news.
He said the boy who raised the alarm was "highly traumatised" by the incident.
He had gone into the water to try to help his friends.
James Weld, 40, who manages owners of the cove, the Lulworth estate, said: "It's a small community. They are local lads and it's a tragedy."
