BOSTON (AP) — A Vermont man who spent a week at sea in a life raft before being rescued by a passing freighter will be reunited with his family in Boston, while his mother is still unaccounted for and presumed dead. The mother and son disappeared Sept. 18 after leaving a Rhode Island marina to go on a fishing trip in the son's 31-foot aluminum boat named the Chicken Pox. Petty Officer 3rd Class Nicole Groll, a Coast Guard spokeswoman, said Carman told the Coast Guard that when the boat started to sink, it went down quickly. "When Nathan comes into port, he'll be met by Coast Guard officials, and they'll get a better understanding of what happened in this particular case and how to better prevent something like this from happening in the future," Groll said.
