An adventurer who planned to row from New York to Scotland was rescued by the Coast Guard late Friday after cutting his head in an accident. Crew members on the Sailfish patrol boat reached Niall Iain Macdonald, 39, around midnight 50 miles off eastern Long Island. “We only had about 50 feet of visibility because the fog was so thick,” Lt. James Provost said in a statement. Macdonald’s face was covered in blood when they found him aboard his 24-foot ocean-rowing craft. “He was in a lot of pain,” Provost said. “He was very relieved we were there.” Macdonald, a television producer for the BBC, was taken to Bayonne Hospital. He took off from Liberty Landing Marina on June 5 for a journey to Scotland expected to take four months.
