Particulars on her dimensions and propulsion, recorded by her Union captors, were later included as a statistical summary in the "Official Records of the Union and Confederate Navies in the War of the Rebellion". In it, it was stated that she measured 217 feet in length, 48.6 feet abeam, and was designed to draw 13 feet of water and 13.6 feet when loaded. A twin-engined vessel, each driving a separate propellor, she was powered by two 22(L)×8.4(W)×9.1(H) feet boilers, heated by a 7(L)×3.6(W) feet furnace with a grate surface area of 96.8 square feet. Recorded is also an appraisal of an inspecting Union officer, who deemed "Texas" as "(...) one of the best and most valuable hulls built by the Rebels". It was only in this summary that the June 22 trial run was mentioned.
