Research was put into the shape of the hull with the objective of making the electric boat run efficiently. This project examined the practical power characteristics of a sightseeing boat of about 20 m in length that would travel at a velocity of 5-8 km/h. It is hoped that the obtained information will be applied to future hull designs. This paper reports result of comparisons between previously proposed characteristics that were tested using a 1:4 scale boat fabricated specifically for this research.
