Thai golf official Sompong Dowpiset will not rest until the Andaman coastline is rebuilt. The chairman of the Thailand Open organising committee lost 100 million baht ($20.3 million) when the tsunami buried Khao Lak. But he carries an even greater burden - the death of King Bhumibol Adulyadej's grandson. Princess Ubolratana and her son Bhumi Jensen were staying at Sompong's hotel in Khao Lak on that fateful Boxing Day morning. Despite being aware of the impending disaster, the 21-year-old royal could not be saved. Sompong was warned of the killer wave from his business partner in Phuket and a few minutes later the sea receded across the mud flats at Khao Lak. He managed to get most people to higher ground, but lost four tourists, 13 employees and 21 members of the royal security guard. 'I'm still suffering from the disaster. The princess and her family were staying in my hotel. I'm very sorry to say she lost her son there. 'As the owner of the hotel I feel deep regret. I can't forget what happened,' said Sompong, who was instrumental in relocating the Thailand Open from Pattaya to Phuket. 'I will do everything to support the hotel industry, the local people and the government. What I do, I will do it with all my will.' Sompong said his hotel in Khao Lak suffered 80 per cent damage, while his hotel in Phuket escaped with 20 per cent damage. 'My partner in Phuket called me and told me about the tsunami. Then four or five minutes later the water went out - about a mile off the beach. We started shouting to people to go to higher ground and managed to save about 30 to 40 lives. 'The security guards went to the princess' villa and took her to safe ground. But her son was not there. His body was found the next morning about 100 metres behind my hotel.' It was reported that Bhumi Jensen was jet skiing at the time, but the princess believed he was on the beach somewhere. Sompong said he was rebuilding his hotel and the one behind him, which he had just bought. He estimated he had lost 'about a 100 million baht' in the disaster. He said the government had made available 70 billion baht to rebuild the area, but it would take a year for Khao Lak to return to normal. Phuket was already back on its feet and moving the Thailand Open to the world-renowned Blue Canyon Country Club was one way of telling the world that paradise still existed, Sompong said. 'The message we are sending to the world is that Phuket is still the paradise it was. By bringing all these players here and the accompanying media, the world will know Phuket is up and running,' he said.
