Several Hatteras-Ocracoke ferry runs will be missed Monday because a vessel is down, according to the North Carolina Department of Transportation.

Because the ferry is not operational, it will miss the 12:30 p.m. run out of Hatteras.  The 11:15 a.m. and 1:45 p.m. runs out of Ocracoke will also be missed.

DOT officials did not explain what caused the ferry to go down.
