Cummins engines for electrical generation and two 950-hp Cummins for slow-speed propulsion. In order to perform its new role as an inland cruise ship, a com- plete reconfiguration of the drive system was specified by naval architects Rodney Lay & Associates of Jack- sonville, Fla. The company suggested a large increase in propulsion power from 1,900-hp to 4,600-hp — thus enabling Columbia Queen to maneuver through the eight locks of the Columbia and Snake Rivers, and high winds — providing a cruising speed of 12 knots. Cascade's crew accomplished this task by opening four access panels in the main deck, and building new machinery space in the stern compartment. The exist- ing 950-hp mains were then raised out of the engine room, and lowered into the stern where they became the auxiliaries, connected to upward-angled shafts turning azimuthing sternthrusters. The 950-hp auxil- iaries were joined to Schottel azimuthing drives with fore and aft propellers fitted in new transom wells. Contractors for the vessel's passenger and public- spaces was Hopeman Brothers of Waynesboro, Va.. who approached the project with a meticulous layout of the new floor design on the original steel deck, followed by the welding of U-section "shoe plates" to the deck wherever walls were indicated. This served as a foundation for a modular wall system, allowing a team of local craftsmen to rapidly subdivide the cavernous interior into recognizable spaces. During sea trials, the vessel achieved a speed of 12 knots with all four engines, and was able to cruise under mains at only 10.5 knots. The combined azimuthing drives with the 350-hp bowthruster gives off a high degree of maneu- verability, while fully-equipped, wing steering stations give the captain total visibility during docking.
