People aboard a charter fishing boat found the remains of an elderly man Thursday about 15 miles off Kennebunkport. It matched the description of Richard Pratt, 80, who disappeared last week.
A Coast Guard crew retrieved the body and brought it to New Hampshire for an autopsy.
Officials said Pratt was a seasoned sailor who set out alone for Maine on August 1st.
A search was launched when his sailboat was later found along the shore of Richmond Island off Cape Elizabeth.
The sails were still up, but Pratt was no where to be found.
