In view of demands of wetland tourism, protection and development, a design scheme for new airboats including rotary electric propulsion plants rather than traditional fuel engines for propulsion was put forward, in which supercapacitors and lithium battery packs are used for composite energy storage and solar photovoltaic power generation devices are used for auxiliary supply energy. Analysis was carried out on the basic structure and principle, key technologies and advantages in this study. The study indicates that such boats take advantages of environmentfriendly supply energy, lowering emissions and wastes, flexible operation, more flexibility, and better adaptability of the wetland environment including more obstacles and complicated water surface situations; moreover, they have high application values and broad development prospects. 
