Just what the doctor ordered — cocaine, ketamine, guns and prostitutes on a multimillion-dollar, 80-foot luxury yacht moored in Massachusetts' Nantucket Harbor on Tuesday.

Police responding to a call to dispatch about a woman's possible overdose aboard the Jess Conn, a "petite superyacht" built by Nordhavn in 2021, have arrested its owner, a former physician from Colorado who retired to Florida.

Scott Burke, the yachtsman, faces a dozen drug and firearms charges following the encounter and a search warrant served on his vessel.

Authorities, including the U.S. Coast Guard, Nantucket police and the local harbormaster, boarded the craft Tuesday morning and found a disoriented woman in the master bedroom.

"[She] appeared to be under the influence of an unknown substance," a police statement of facts read. "She also stated that she did not feel safe."

She was taken to the Nantucket Cottage Hospital, police said.

Police also found a loaded handgun and a pink bag of cocaine in the room, the court documents allege. After obtaining a search warrant, police say they recovered 43.4 grams of cocaine and 14.1 grams of ketamine.

A source close to the investigation reportedly told the Nantucket Current that authorities also encountered prostitutes on board. 

"That's certainly not in my press release," Lt. Angus MacVicar, the Nantucket Police Department's public information officer, told Fox News Digital on Thursday.

Burke allegedly told police he had a license for the handguns — but police said his Florida license was not only invalid in Massachusetts, it expired last year.

Police initially charged him with possession of two handguns and a bag of cocaine and tacked on more charges after obtaining a search warrant for the boat.

A thorough search conducted by police, the USCG and DEA found more drugs, ammunition and large-capacity magazines.

Nordhavn's 80-foot trawler has been described as a "mini-superyacht," and costs more than $7.5 million, according to Motorboat & Yachting magazine.

Options include a hot tub on the flybridge and herringbone floors. The model is marketed to globetrotters who enjoy summers in the Mediterranean and winters in the Caribbean, according to the outlet.

Burke's vessel is reportedly registered out of the Cayman Islands.

Manufacturer specs show the vessels can carry more than 4,600 gallons of fuel and are powered by twin 375 hp John Deere engines. They come with four staterooms and housing for up to two crew members.

In May, a member of YachtForums.com shared a photo of Burke's boat run aground off the Florida Keys, but it reportedly suffered little damage and was pictured in a West Palm Beach marina days later.

The doctor has been released on bail, but attempts to reach him for comment were unsuccessful Thursday morning.

Public records show Burke obtained his medical license in Colorado in 1981. It was last renewed in 2019. He has owned at least two other large vessels over the years, 90 and 58 feet long, also named Jess Conn. 

According to his LinkedIn profile, Burke also founded a medical lien service firm called Injury Finance in 2003 and as a physician specialized in spine rehab and pain. His bio said he retired from active medical practice.

The investigation remains ongoing, but police declined to comment on potential additional charges.
