The friends and families of British victims of the Bahrain pleasure boat disaster have spoken of their shock and "terrible loss".
Jason Brett and his wife Lucinda Lamb were among the victims
Their tributes came as more details emerged about the 12 Britons and three people with dual UK nationality who were killed in Thursday's tragedy.
In total 58 people died when the boat capsized during a party.
Bahraini officials have revealed it did not have a licence to sail as a pleasure cruiser.
Foreign Office Minister Kim Howells has promised to monitor developments in the Bahraini inquiry.
Those on board were celebrating the completion of the World Trade Centre skyscraper in Bahrain's capital, Manama.
David Evans, 56, chairman of the Murray and Roberts project, lived "between Glasgow and Bahrain".
His former wife Julie said: "David and I had been married for 26 years and myself and our two children are devastated by our loss in this terrible tragedy."
Colleague Will Nolan, 50, was director of the skyscraper project and was also killed.
His wife Nicola reportedly survived the accident and is now consoling her 18-year-old daughter and 16-year-old son.
Mr Nolan's friend Ivor Palmer said: "The family are very upset and distraught. It's a huge tragedy."
Scott Belch, 33, a civil engineer for the firm Atkins from Redhill, Surrey, and his German wife, Sandy, who married six weeks ago, were also among those who died.
Mr Belch's parents paid tribute to their 6ft-tall son as a "big loveable bear".
Stephen Grady, a 42-year-old contract painter and decorator from Hebden Bridge, West Yorkshire, was also among those who died.
His wife Stephanie is expecting their second child. She described her husband as a "wonderful" father and husband who was popular among his friends and colleagues.
Family and friends of 59-year-old Jimmy Allen also paid tribute to him. Mr Allen, who was born in England but also lived in South Africa, had worked for Murray and Roberts for 23 years.
His widow Pauline said Jimmy was a "caring, loving husband and father who really enjoyed life".
Another couple - Jason Brett, a manager for an engineering and architecture company, and his wife Lucinda Lamb, who worked for a property consultancy - were also among the dead.
They were named by Mr Brett's firm Atkins.
Mr Brett's parents arrived in Bahrain to look after the couple's two young children.
Bob Hope, Atkins director for the northern Gulf, said: "Jason was an outstanding employee and, together with Lucinda, we have lost both a friend and colleague."
Survivor Simon Hill told reporters there had been concerns about the boat's stability even before it left port.
Mr Hill, from Murray and Roberts, said he had been told its capacity was about 200 people.
But while in port, it "was starting to sway from side to side, causing several people to feel uneasy", he added.
The boat eventually sailed with about 130 people on board. Some 16 or so had decided to leave beforehand, Mr Hill said.
The vessel capsized almost two hours later as it was beginning to return to port.
Mr Hill said some passengers had been pulled onto the upturned hull.
Those trapped inside, below the water line, had tried in vain to smash windows to escape, he added.
'Lack of counsellors'
Many of the British expatriate community attend St Christopher's Cathedral in Manama. Cathedral Dean, the Rev Alan Heyday, said there was a lack of counsellors to help those in grief.
However, he added the community was "doing a wonderful job" in offering support and people were ringing in asking how they could help.
"People mostly need to be quiet and come to terms with what's happened to them, they need to be spiritually comforted," he said.
Messages are being left in a book of condolence at the cathedral.
