MS Yavari The world's oldest iron kit-built ship. Designed by James Watt & Co and built in 1862 by the Thames Ironworks & Shipbuilding Co, she was assembled on the shores of Lake Titicaca, Peru and launched in 1870. Now powered by a 1914 4-cylinder Bolinder hot bulb semi-diesel engine producing 320bhp at 225rpm, MS Yavari is an enduring symbol of the ingenuity and global reach of British engineering.
