A floating pirate-themed café and restaurant was flooded and left partially underwater by rough seas off Pattaya on Monday evening. Nobody was hurt.
The double-decker raft, named Krakenian, offers dining, live music, a karaoke room and squid fishing.
It began listing to one side as it was hit by waves driven by strong winds around 4pm on Monday. It was flooded and partially submerged.
There was an unconfirmed report of a problem with a water pump not working properly. Rescuers helped employees to safety. There were no guests on board.
The pirate-themed restaurant was only recently opened.
The restaurant had been closed for some days because of the poor weather and rough seas.
An executive said water had entered the side of the boat and caused it to list heavily. The entire raft did not sink.
The hull was nose-down and resting on the sandy sea floor. The water was not deep.
Raising it back to the surface would take about one hour once the operation got underway, officials said.
