Royal Mail Ship

Royal Mail Ship (or Steamer), usually seen in its abbreviated form RMS, is the ship prefix used of any seagoing vessel that carries mail under contract to the British Royal Mail.

The designation has been used since the 1840s. It was used by a large number of companies, but is often associated in particular with the Cunard line, which held a number of high-profile mail contract business, and which traditionally prefixed the titles of all its ships with the initials "RMS". The best-known ship carrying the prefix is almost certainly the RMS Titanic of the White Star Line.

Technically, a ship would use the prefix only while contracted to carry mail, and would revert at other times to a standard type designation such as "SS".

Initially the Admiralty operated these ships. In 1850 contracts were awarded to private companies. The most valuable route, with the highest volume, was between Kingstown (now Dún Laoghaire), in Ireland, and Holyhead in Wales. The CDSPCo (City of Dublin Steam Packet Company) won the contract and purchased RMS Saint Columa and RMS Llwywllyn from the Admiralty.

Having the title RMS was seen as a mark of quality and a competitive advantage, because the mail had to be on time. In the 1860 CDSPCo contract there was a penalty clause of £1.1.4 (one pound and one shilling and four pence) for every minute's delay.

In recent years the shift to air transport for mail has left only a few ships with the right to the prefix; notably RMS St. Helena, which serves the island of St. Helena in the South Atlantic, and RMS Queen Mary 2.
