SS Binnendijk was a Holland America Line (NASM) cargo steamship. She was one of NASM's "B" class ships: the company's first cargo ships to be powered by steam turbines. Binnendijk was built in South Holland in 1921, and sunk by a mine in the English Channel in 1939. She was the first ship that NASM lost in the Second World War. Her wreck off the coast of Dorset, England is now a wreck diving site, nicknamed "The Benny".
Some sources anglicise the ship's name to Binnendyk. However, Lloyd's Register always recorded her as Binnendijk.
"B" class turbine steamships
Until 1920, every NASM cargo ship was propelled by a reciprocating steam engine; in most cases triple-expansion. However, in April of that year C. van der Giessen & Zonen's shipyard in Krimpen aan den IJssel laid down the first of a class of new ships of about for NASM. Each member of the class was to be driven by two Brown-Curtis steam turbines, driving a single screw via double-reduction gearing.
Van der Giessen launched the first ship in October 1920 as Burgerdijk, completed her in June 1921,
