Humphrey & Dowerman Shipyard - Robet E. Lee steamboat build site

The Robert E. Lee, nicknamed the "Monarch of the Mississippi," was a steamboat built in New Albany, Indiana, in 1866. The hull was designed by DeWitt Hill, and the riverboat cost more than $200,000 to build.
It was named for General Robert E. Lee, General in Chief of the Armies of the Confederate States. The steamboat gained its greatest fame for racing and beating the then-current speed record holder, Natchez, in an 1870 steamboat race.

Shipyards in New Albany weren't large cranes, steel and welders. What you needed was a stretch of river bank, an army of carpenters and lots of wood.
