Patrol Boat 813 was built in 1994 and operated under Marine Police Station 1, Division 8 Marine Police Bureau, Pak Nam Sub-District, Mueang District, Ranong Province in the Kingdom of Thailand. The primary role of Patrol Boat 813 was to protect and secure the VIPs of the country and on the morning of the 26th December 2004 Patrol Boat 813 was anchored approximately one nautical mile offshore in front of the La Flora Resort in Khao Lak whilst Thai Prince Khun Poom Jensen was jet skiing.
Several hours earlier the third largest earthquake ever recorded on a seismograph struck off the west coast of Sumatra, Indonesia. The subsequent tsunami swept the Prince from existence and washed Patrol Boat 813 almost two kilometres inland killing the entire crew. Other members of the Royal Family were lucky to escape with their lives by sheltering in the upper floors of the resort.
Today the boat stands where the tsunami placed it and is kept as a sombre memorial to the estimated 227,898 people killed by the monstrous waves.
