SS Japan
A wooden sidewheel steamer of the Lincoln era. A wreck the ocean kept.
She was Pacific Mail's flagship - the largest American wooden sidewheel steamer in the Pacific, when fire took her in the South China Sea on December 17, 1874.
Abraham Lincoln signed her into existence. $10.47 million in silver trade dollars went down with her. 150 years on the ocean floor. 400 souls. A story most people have never heard - but deserves to be known.
The perfect palace of a ship.
