SS Servia

SS Servia, also known as RMS Servia, was a successful transatlantic passenger and mail steamer of revolutionary design, built by J & G Thomson of Clydebank (later John Brown & Company) and launched in 1881. She was the first large ocean liner to be built of steel instead of iron, and the first Cunard ship to have an electric lighting installation. For these and other reasons, maritime historians often consider Servia to be the first "modern" ocean liner.
