On 26 December 2004, Thailand lived one of the darkest episodes in its history, a tsunami of an incredible magnitude struck the south coast of the country. Khao Lak was the most affected city. The wave penetrated more than 1 kilometer inland and took a police patrol baot, the Police Boat 813, almost 2 kilometers from its anchorage on the land, where it is now exposed. A memorial is being built around the ship to remember the tragedy and honor the victims.
