Nine people were hurt when a speedboat crashed into a fishing boat off Cape Bali Hai in Pattaya late Monday night.

The Pattaya City sea rescue unit said the crash occurred about 11pm, resulting in injuries to six Thai women, two Russian females and a woman from Ukraine.

All were pulled to safety and then taken to hospital. It was unclear whether the injured were passengers on the speedboat or the fishing boat.

The boat skipper, named only as Pong, said he took his passengers out fishing off the cape, with the vessel's lights on. The speedboat came out of nowhere and hit his vessel, he said. The impact sank the speedboat.

Pattaya police said the speedboat was taking 27 Thai and foreign tourists from a seaside restaurant back to the bay pier. The boat driver said he did not see the chartered fishing boat.

The police investigation was continuing.
