more persons to see through them. We think the larger windows will really be appreciated during rainy and cold weather." Mr. Reuther said the Creole Queen will also be the first of its type to use diesel-electric propul- sion. "We chose this system be- cause it makes the boat quieter, more fuel-efficient, and vibration free. It also gives us greater safety underway and in docking because of finite controls," he said. In a diesel electric system the generators feed power into a pre- fabricated General Electric sili- con-controlled rectifier unit (SCR) which converts the AC power into DC power. The power pool thus created is similar to an electrical power plant, from which power can be drawn as required. The Creole Queen will operate on two of the three generators with the third in reserve as a spare during maintenance or it can be used for additional power. As the generators are linked to the SCR system, one, two, or three can be utilized as needed in sev- eral voltages. The SCR system will also provide power to the boat's 200-hp Schottel bowthruster, as well as supply power for all of the vessel's other electrical power requirements. The diesel electric system allows finite control of the paddlewheel and bowthruster and eliminates costly clutches, and other expen- sive components while simplifying machinery requirements. "The Creole Queen will also uti- lize a new Halter developed drive system to the paddlewheel which eliminates the possibility of water pollution posed by chain, oil, and hydraulic fluid associated with some other systems," said Mr. Shopf. "In addition," he added, "it will also eliminate vibration and much of the maintenance required by other methods." A key element in the Halter sys- tem are two totally sealed, high- torque planetary gears. One is located on each side of the paddle- wheel and is driven by a D.C. mo- tor. Mr. Shopf said the Halter unit is a significant advance and that the company has applied for patent rights on the system.
