A man in need of emergency assistance while aboard a tugboat Monday morning off Southold was rescued by the U.S. Coast Guard, officials said.

The Coast Guard Sector Long Island Sound received a call about 11:15 a.m. reporting a 56-year-old diabetic man on the tug near Race Rock had been vomiting for a day and requested a medical evacuation.

The Coast Guard dispatched a 29-foot response boat that had been conducting training nearby to rescue the man.
