Gideon Welles being secretary of the navy was already on 29 April 1861 informed by James B. Eads that the snag boat known as the Submarine No. 7 was suitable to be rebuild as a so-called cotton-clad. This center-wheel snag boat build by the navy was now property of Eads’ Missouri Wrecking Company and was used to salvage ships sunk on the Mississippi. She was a catamaran with two hulls each divided by 7 watertight compartments. This made believe Eads that she could suffer badly from enemy gunfire without sinking and for a sum of 3,000 dollars she could be rebuild ad a so-called cotton-clad armed with 32-pdr guns. . She was begin November 1861 for a price of 2,600 dollars as a rebuild by James B. Eads at St. Louis.
