Electric Boats have been around for over 100 years in one form or another. With the advance of electric motor, battery and controller technologies, electric boats are quickly becoming a viable and desirable option. As the price of traditional forms of energy and concerns for the environment and water quality continue to surface, electric boating becomes an important economic factor as well.
