El Horria (originally called Mahroussa) was a Royal Yacht built for Isma'il Pasha, the Khedive of Egypt in 1865. It was built by the Samuda Brothers on the River Thames and designed along the same lines as HMY Victoria and Albert II, and remained in service with the Egyptian royal family until 1951. In 1869, the Mahroussa gained fame as the first ship to pass through the newly completed Suez Canal as part of the opening ceremony.
