An introduction to the hydro-generation system developed for SY Zero, showing how sailing yachts can produce clean energy while underway. It explores the move from diesel generators to quiet, self-sufficient systems powered by wind, solar, and water. The presentation combines practical engineering insights with design and comfort benefits, showing how hydro-generation can improve efficiency, onboard experience, and sustainability. SY Zero demonstrates a new direction for the yachting community — efficient, independent, and quietly capable.
