Solar Sailor clearly articulates the choices that need to be made when designing, constructing and operating a commercial boat. Robert Dane takes us through a personal journey that starts with an observation and a question, and results in the building of a ferry for Sydney Harbour, that utilises a hybrid power system. Interviews with Grahame Parker, Naval Architect, show the importance of planning and testing to produce maximum efficiency. This program is an informative, rich and valuable resource to use when studying the design process, including investigating, designing, producing and evaluating. Students' science knowledge and understanding will also be vastly enhanced, specifically in areas such as energy, power sources and alternative energies.
