This paper presents an overview of fuel-efficient design aspects of a 100-meter vehicle and passenger ferry for service in the Gulf of Alaska and the Aleutian Islands. The paper will discuss the unique design requirements for a small RoPax ferry operating in harsh conditions together with design choices for meeting the requirements in a fuel-efficient manner. A cost-based methodology for decision-making was developed to guide the design process. Functionally equivalent alternatives were selected to meet operating requirements and then evaluated on life-cycle cost. Energy cost typically dominated the life-cycle cost evaluation. This paper discusses the functional requirements and cost saving advantages of the optimization of hull lines, optimization of propulsion plant, and stabilizer fin selection.
