That's double the two jet-skis that have been spotted operating off the beach recently.
''If the operators are repeat offenders, they risk losing their permission to operate,'' said the director of Marine Office 5, Phuripat Theerakulpisut.
He said he would send Marine Office 5 staff to investigate. Swimmers complain loudly about the unwanted noise machines.
A jet-ski has also been spotted recently at Layan, a so-called ''virgin'' beach.
With 286 jet-skis operating on Phuket, authorities struggle to confine them to beaches where they are permitted to operate.
As Phuket grows and tourism becomes more popular, the prospects of stopping jet-skis from spreading to other beaches remain slim.
Jet-skis that now operate freely along with parasailers at Patong, once the holiday island's premium swimming beach, are likely to again be a topic when honorary consuls meet with Phuket's governor on December 17.
Partial insurance is just a partial answer to the jet-ski problem, with questions recently asked about what insurance covers the parasailers, who take over large sections of Patong for takeoffs and landings.
Having been a regular at Surin beach for over 10 years, jet skis have always operated there. And they have also intimidated anyone who has tried to move them on.Marine 5 need to station people at the beach for 8 hours a day - every day.
