Since solar energy produces no by-products and consumes no natural resources, it is the from of energy that provides the greatest potential for the future. So far in the history, There are no records whatsoever on the use of solar energy as a source of power for marine vehicles. Moreover, there is only a handful of documented accounts where such an attempt has been made. The purpose of this research is to present the design of a solar boat with the aim of increasing its practicality. In particular, considerations on the optimal design and performance testing of the solar boat are presented. Furthermore, the use of solar cells and battery as a power source, the design of a body with minimum resistance, and the design of a propeller with low loading and high efficiency is investigated and tested in detail. At the end, putting together the various crucial factors as mentioned above, the overall performance of the solar boat is evaluated.
