The parents of two brothers swept to their deaths as they waded in the sea have paid tribute to their "wonderful" boys.
James and Matthew Hole, from Worcestershire, were playing in the sea off Llandanwg Beach, near Harlech, north Wales, on Thursday evening when a freak current dragged them under the water.
James, aged 16, was washed up on to the beach 25 minutes after disappearing from view and was taken by air ambulance to hospital, but died on Friday night.
Matthew, 14, died at sea and his body was found 24 hours later.
Attempts by older brothers Simon, 19, and Stephen, 18, to find their brothers were in vain.
Kevin and Sue Hole paid tribute to all four sons and the emergency services, who launched a massive air, sea and land rescue bid.
The sea off that section of the Welsh coast was calm that night, said coastguards.
But Stephen, who had been watching Simon, James and Matthew from the beach, said his brothers were still careful to stay in shallow waters.
Mr Hole, 46, from Hagley, said: ?We have always spoken to the boys about safety. We have always talked about thinking carefully about the consequences of what they are doing.
?Whilst in the water Matthew commented to his other brothers that we shouldn?t go too deep to keep out of trouble.
?But you can?t wrap your children up in cotton wool. They are at a responsible age and becoming independent.?
Mr and Mrs Hole paid tribute to their older sons, Simon and Stephen, for their part in the rescue attempt.
Mrs Hole, 47, said: ?They both played an important part. Simon did what he could and we are thankful he did the sensible thing and not endanger his own life. To lose two children is bad enough.
?Stephen reacted on shore quickly and rang 999 and spent a lot of time on the phone with directions and describing what they were wearing.?
The couple praised the emergency services and the staff at the hospital, where James was treated.
?We know they all put a lot of effort into James at the hospital and could not have done any more,? said Mrs Hole.
Mr Hole said: ?Matthew was an active lad. He was very bubbly and the sort of character who made friends quite easily. He was well liked.
?He was a bright lad and had good potential in that sense. He was always on the go. He followed his older brothers in sharing a like of mountain biking. He and James were really following in their footsteps.?
The couple described James as a quieter lad. ?He was the gentle giant of the family,? said Mrs Hole.
?James had to work hard academically but always put the effort in. He never knew his excellent GCSE results.
?He was a quieter child and in that sense he was a very thoughtful child.
His first instinct would be to go and help.? The couple also had two younger sons, Daniel, four, and eight-year-old Benjamin.
Mr Hole said: ?Until we get back into our own home and start to do those things we do for the first time as a six, we will really not know how we will cope. But we will, with the support of our close extended family.?
Earlier Simon told how he fought in vain to save Matthew and James, but the boys were sucked under in seconds.
Simon, who lives with his family, said: ?Matthew was shouting, ?I?m in trouble, I?m in trouble?.
?From either side, me and James tried to get to him. But then I just managed to get out with the strong current.
?As I tried to get out, James got into trouble. Ten seconds later and I could not see either of them.?
Simon also revealed that James, a pupil at Haybridge High School, had gained top grades in his GCSEs ? three A*s, three As and five Bs.
