A Maine man reported missing by his wife after he did not return from a sailing trip on Casco Bay has been located. The Coast Guard says 79-year-old Albert Kelsey was spotted early Wednesday morning. His 20-foot vessel had apparently run aground at low tide and got stuck in the mud. He appeared to be in good health. The Coast Guard said the South Freeport man was last seen departing from a local marina at about 5:30 p.m. on Tuesday and was scheduled to visit two Casco Bay islands. He was reported overdue by his wife at 10 p.m. A 25-foot response boat small from Station South Portland, a Jayhawk helicopter from Air Station Cape Cod, and a boat from the Maine Marine Patrol took part in the search.
