The Coast Guard is searching for the sole crew member aboard a sailboat making a Maine-to-Florida trip that hasn't been heard from since Sunday.

The Coast Guard says 61-year-old Stephen Crane last reported his position as he rounded Cape Cod, Mass., Sunday. They say his sister notified the Coast Guard the 31-foot Southern Cross sailboat called the Austina did not arrive in Cape Hatteras, N.C., as expected Thursday afternoon.

Crane departed Portland, Maine, on Aug. 1 and was headed to Fernidina, Fla.

The Coast Guard says its sectors along the east coast are attempting to reach the Austina. Additional crews are scheduled to make aerial searches Friday morning.

Anyone with information is asked to contact the Coast Guard.
