  Recently worldwide interest is growing toward commercial, military or
scientific Unmanned Surface Vehicle (USV) and hence there is required to
develop their guidance, navigation, and control (GNC) systems. Real USVs are a
relatively new advent, so the drawbacks of each model will be modified during
the time. The proposition of an environmentally friendly as well as high
efficient USV's design are the main purposes of this paper to guide future
researches. Power management between renewable sources and storage units is
considered. Furthermore, suitable and modern sensors are applied for state
estimation and environmental perception. Technical requirements relate to
guidance and control methods are provided to achieve the highest performance in
the environment. Also, the hull structure and its material are important
factors that are considered in this paper.
