This document summarizes several ferry designs and their fuel usage and costs. It compares the current ferry design to designs using Andy engines, which are more fuel efficient and can reach double the speed. The Andy single speed design would use less fuel and emit fewer CO2 emissions per year than the current design, while the double speed and double load Andy designs would allow ferries to transport more passengers and freight using less fuel. Adopting Andy engines across various modes of transportation could save over 12 million tonnes of fuel per day, valued at over 7 billion.
