The disaster management department said there were 93 tourists on the boat with 12 crew members and 39 on the yacht with two crew members. It said that all the passengers had been saved from the yacht, meaning that all the casualties were from the boat. “On the same day, a Russian couple’s jet ski overturned near Koh Racha, 15 kilometres from Phuket, however, they have already been rescued,’’ Somsak said. Police attributed the cause of the incidents to strong sea currents and wind. Thailand is in the middle of its rainy season, with sailing often not advisable during this time.
