Four people were rescued from a 35-foot boat when it caught fire Sunday afternoon near the Bridgeport & Port Jefferson ferry terminal and Danford's Marina, authorities said.

A Suffolk police sergeant, Michael Guerrisi, was off-duty and on his personal boat when he saw the 33-foot Sea Ray Sundancer on fire in Port Jefferson Harbor at about 12:50 p.m., Suffolk police said.

Guerrisi pulled four people who were in the water onto his personal boat after they abandoned their burning vessel, police said in a release. 

The Port Jefferson Fire Department responded to the scene at 12:50 p.m., officials said.

Port Jefferson Second Assistant Fire Chief Anthony Barton said the boat was “free standing” near the docking area when the fire started.

The owner of the boat that caught fire, Charles Schwartz, 59, of Greenwich, Conn. and Ainsley Lothrop of Norwalk, Conn. were taken to Stony Brook for evaluation. David Lamontagne, 47, of Norwalk and Robert Corbi, 31, of Greenwich were taken there with non-life-threatening injuyries.

The fire is under investigation by the Suffolk County Arson Squad.

Port Jefferson Fire Chief Brennan Homes told News 12 his department was notified about the fire by a Lake Grove fire marshal who was on the docks at the time.  

When the fire department arrived, the boat was fully engulfed in flames and floating toward the marina, Homes told News 12. At one point, the boat got within 10 feet of the other boats but crews pushed it into open space.

ire-retardant foam was sprayed on the boat to extinguish the fire. The Port Jefferson and Lake Grove fire departments were assisted by Terryville Fire Department, Setauket Terryville Fire Department and Mount Sini Terryville Fire Department as well as Port Jefferson Volunteer Ambulance Squad.
