Police Boat 813 in Khao Lak marks the location where 10 years ago the Asian tsunami made its most graphic entrance, courtesy of those horrifying holiday videos showing the sea in the form of a massive wave sweeping up lives and buildings, mostly hotels in its path. In addition, this was the location used for The Impossible, the Ewan McGregor film set amid the tsunami. And finally, it also has the tragic distinction of being the Thai resort that recorded the most deaths in the disaster, conservatively put at 3,950 including a member of the Thai royal family. Police Boat 813 was at anchor about 1 nautical mile off the coast of Khao Lak, where Her Royal Highness Ubonrat Rajakanya Siriwaddhana Phannawaddee was staying at the La Flora Resort with her son and daughters. When the tsunami struck, the boat was swept inland almost 2 kilometers, to where it sits today. The boat was left where it landed and is now maintained as a memorial. The princess lost her only son on that fateful day when the tsunami swept Thailand and other countries in the region.
