The Coast Guard's search for a missing boater from Massapequa was called off Monday evening, a day after police said he fell from a speedboat into the Great South Bay in the waters outside Babylon Cove.

Suffolk County police identified the boater as 28-year-old James Jaronczyk and said he was alone on a 22-foot Progression speedboat when he went into the water just after 4:30 p.m. Sunday.

Hunter Medley, a spokesman for Coast Guard's Long Island Sound sector in New Haven, said the search for Jaronczyk was called off indefinitely at 8 p.m. "pending further developments."

The Coast Guard searched for Jaronczyk for 34 hours and covered approximately 1,000 nautical miles, Medley said.

Suffolk County police said their search for Jaronczyk is still ongoing.

There are no indications at this point in the investigation, police said, that the boat was involved in a collision with another vessel.

According to statistics from Stony Brook University, the water temperature Monday morning from Buoy No. 1 in the Great South Bay was between 59 and 60 degrees. A hypothermia table from the National Center for Cold Water Safety indicates that survival, at that temperature, would last between one and six hours.
