St Edmund was a turbine screw car ferry built for British Rail (BR) in the early 1970s.

[2] On 20 May, St Edmund, set sail from Devonport for the Falkland Islands with 5th Brigade troops along with some members of the Royal Air Force.

[1] On Good Friday 1983, St Edmund was commissioned formally into the Royal Navy as HMS Keren with a crew of 35.

With the addition of extra refrigerated storage in the car decks and a new water osmosis plant, Keren could accommodate approximately 1000 troops.

[clarification needed] In July 1985, Keren returned to the UK and, after a government funded refit at Vosper Thornycroft in Southampton, she was laid up near Portsmouth for sale.

In January 1986, Keren was sold to the Cenargo Group who operated the Ferrimaroc service between Almeria in Spain and Nador in Morocco.

By February the ship had been chartered by British Channel Island Ferries, operating from Poole to Guernsey and Jersey as the Rozel.

[2] During the summer of 1993, the ship was chartered to Compagnie Marocaine de Navigation (COMANAV) for the Nador to Port-Vendres service.
