He put clothes on this time — but shook off the authorities.

The disturbed man busted for a naked joyride on two stolen boats in a Manhattan marina escaped from a local hospital Wednesday – disguised with a lab coat but no shoes, cops and sources said. 

Stephen Blasetti, 36 – who was being held on grand larceny, criminal possession of stolen property and reckless endangerment charges in connection to the clothes-less Saturday romp – escaped from Columbia University Irving Medical Center around 6:30 a.m., police said. 

Blasetti was last seen wearing a lab coat, blue hospital pants and hospital socks but no shoes when he bolted from the hospital’s Milstein building on Fort Washington Avenue near West 168th Street, according to the sources.

It was not immediately clear how he managed to flee the hospital, where he was being held since NYPD Harbor Unit cops arrested him. 

He was not shackled or handcuffed, the sources said. 

The chiseled Blasetti hopped into the smaller, dinghy sailboat at the Dyckman Street Marina around noon Saturday after employees there kicked him out because he was acting erratically, cops said. 

Blasetti – who a police source said was high on methamphetamines – was already sailing into the Hudson River before employees could stop him, cops said.

But the NYPD’s Aviation and Harbor Units were quickly notified and went on the hunt for the hard-to-miss nutjob, cops said.

The seafaring kook then sailed that boat up to a larger, anchored catamaran sailboat and climbed on board that vessel, police said.

Members of the Harbor Unit quickly responded and got on board the catamaran too, arresting Blasetti, cops said. 

That’s when he was taken to Columbia University Irving Medical Center for treatment, police said.

Besides the boat incident, he has no open cases in the Big Apple, cops said.
