An official aboard the HTMS Hua Hin patrol ship said another two bodies were found on Friday afternoon.
One of them was a boy, who appeared about 10 years old, and the other a man who appeared to be about 35 to 40 years old.
The figures detailing the retrieved bodies and still-missing tourists were still being revised.
The boat with 105 people aboard sank while returning from Koh Racha to Phuket.
