The yachting industry is undergoing a dynamic transformation driven by global environmental policies, technological advances, and rising societal awareness of sustainable transport. Conventional motor yachts powered by fossil fuels contribute significantly to greenhouse gas emissions and local pollution, prompting increasing interest in alternative propulsion technologies. This article examines two of the most promising solutions—electric propulsion and hydrogen fuel cells—focusing on their technical characteristics, economic feasibility, and environmental impacts. A methodological framework was developed to assess modern fuel station infrastructure for motor yachts, applying criteria such as availability, safety, energy efficiency, and regulatory compliance. Life-Cycle Costing (LCC), Net Present Value (NPV), and Life Cycle Assessment (LCA) analyses were conducted to compare the long-term economic and ecological performance of electric charging and hydrogen refuelling stations. Case studies from Europe, North America, and Asia illustrate the rapid expansion of alternative fuel infrastructure, ranging from high-power DC charging and wireless inductive systems to containerised hydrogen stations integrated with renewable energy sources. The results demonstrate that electric propulsion is best suited to short-distance recreational navigation, while hydrogen offers advantages for long-range and intensive applications. The study concludes that both technologies will likely coexist as complementary solutions, with investment potential concentrated in tourist-intensive waterfronts and urbanised port areas. Future prospects include innovations in wireless charging, local green hydrogen production, and hybrid infrastructure, reinforcing the role of marinas as active players in the maritime energy transition.
