**Two Burmese fishermen and a 17-year-old boy have been jailed for murdering a yachtsman from East Sussex off the coast of Thailand.**Malcolm Robertson, 64, of Hastings, was bludgeoned and thrown overboard off the Andaman coast after the pirates boarded his vessel, the Mr Bean, in March.
His wife Linda was left fearing for her life as they kept her tied up for about 10 hours before they fled the yacht.
The Foreign Office said the killers were sentenced in Thailand on Thursday.
The men, who had pleaded guilty, were each sentenced to 25 years in prison at Satun Provincial Court.
The boy, who was convicted of murder, was jailed until he reaches the age of 24.
Body found
Thai fishermen found the body of Mr Robertson 10 nautical miles north of Satun’s Lipeh Island a week after the attack.
His killers were named in reports from Thailand as Eksian Warapon, 19, an 18-year-old known as Aow, and the 17-year-old , known as Ko.
The reports said they had been stranded on an island after jumping from a Thai fishing ship.
After finding the island had little food and water, they killed Mr Robertson when they boarded his anchored 44ft yacht, named after the chain of coffee shops he ran.
They ate the couple’s food supplies and fled the boat but were later arrested on a raft about half a mile from the couple’s vessel.
Mrs Robertson escaped with minor injuries but detailed her ordeal during 10 hours of testimony in Satun, describing how the attackers tied her hands and feet and how she heard her husband tell them: “Get off my boat.”
Mr Robertson was semi-retired and had passed the running of his chain of coffee shops in East Sussex to his children.
He was fulfilling a lifelong dream of spending winter months sailing around warmer climes with his wife.
The couple, both qualified yacht masters who had sailed round the world, had been married for 25 years and had four children and seven grandchildren.
More than 150 mourners gathered at his funeral service at St John the Evangelist Church near their home in St Leonards-on-Sea where it was said he “chased his dream” of world adventure.
