Ben-my-Chree was built by Robert Napier and Sons at Glasgow in 1845 at a cost of £11,500.

Boiler pressure had increased slightly in the 13 years since the start of the Steam Packet Company, and this vessel's was 20 pounds per square inch (140 kPa).

Ben-my-Chree has the distinction of being the first iron-built vessel in the Steam Packet Fleet.

She was sent to Leith, Scotland, and sold by Tod and McGregor for £1,200 (equivalent to £142,374 in 2023)[4] to the African Steamship Company.
