For H. M. Post Office, Dover station. The Arrow was built by W. Evans of Rotherhithe. She was moved to the Port Patrick station in 1825, but in 1833 she was fitted with 30 horse engines and returned to Dover for the Ostend service. She was re-named Ariel in 1837 when the Navy took over the Post Office packet fleet. As Ariel, she took part in trials against the the screw-propelled boat Archimedes in 1840.
