The ship was built by Wigham Richardson, Wallsend, in the United Kingdom, and launched on 21 May 1894. Boris arrived in Bulgaria on 2 July 1894 at 9.30 am in the Bay of Varna. In the first years the ship carried out voyages between the Bulgarian ports. On 21 September 1915 the ships Cyril, Boris, Bulgaria, Varna, and Tsar Ferdinand were moved to Lake Varna and anchored against the Cotton Factory. In 1920, the ship was struck by the Russian steamer Kronstadt near Sevastopol, during the evacuation of the remnants of the Bulgarian military in the Crimea. The Russian side found Sakharov, the captain of Kronstadt, guilty. As a result, Russia offered to replace the Boris with the Yalta.
