Evolution of the
Great Lakes Self-Unloader

On
a warm summer afternoon in 1927 off South Haven, Michigan, an
old barge began taking on water. Helpless to staunch the flow
and realizing their vessel would inevitably sink, the crew
escaped to the accompanying tug, and watched as their ship
plunged beneath Lake Michigan. Its loss unlamented, its career
unheralded, it slumbered on the sandy bottom in the same
obscurity that had shrouded its earlier work days as a steam
freighter sailing the Great Lakes. However, the vessel’s
anonymity ended in 2006 when Michigan Shipwreck Research
Associates located the sunken wreck of the Hennepin. It
is now listed on the National Register of Historic Places as the
world’s first self-unloading vessel.
Buckets
and Belts: Evolution of the Great Lakes Self-Unloader
traces more than a century of innovative technological advancements
in the conveying of bulk cargos from the Hennepin’s
conversion to a self-unloader in 1902 to today’s mammoth
thousand-foot long lakers.
Enhanced with the most comprehensive collection of self-unloader
images ever published and dozens of underwater photographs, the
book also explores the lives of the people who designed these
vessels, the crewmen who sailed them and the self-unloaders that
tragically went to the bottom, often taking entire
crews with them.
