A 22-year-old Vermont man was found alive Monday after spending more than a week in a life raft after the 31-foot aluminum fishing boat he was in sank.

Nathan Carman and his mother, 54-year-old Linda Carman of Middletown, Connecticut, left Ram’s Point Marina in Point Judith, Rhode Island, for an offshore fishing trip Saturday, Sept. 17, according to a Coast Guard report. Avid anglers, the pair were reported missing the next day when they didn’t return to the marina.

The Coast Guard says it searched more than 62,000 square nautical miles before suspending the effort last Friday, Sept. 23.

Carman told the Coast Guard he got into the life raft when their boat took on water and sank Sept. 18, according to published reports. He was unable to find his mother, who remains missing and is presumed dead.

There was no distress call made, according to the Coast Guard.

A freighter crew spotted Carman in the life raft Sunday, Sept. 25, 100 miles off Martha’s Vineyard, Massachusetts. He arrived in Boston on Tuesday and was reported to be in good condition.

Carman is said to have Asperger’s syndrome and had gone missing in 2011 after the loss of his horse, according to a Fox News report. He was found in Virginia unharmed a few days later.
