Electric-powered boat or marine vessel

Abstract

A marine vessel includes a hull assembly, and the hull assembly includes a deck assembly, a first battery assembly, a second battery assembly and an electric motor assembly. The deck assembly is contained within the hull assembly. The first battery assembly is located completely under the deck assembly. The second battery assembly is located completely under the deck assembly and is physically separate from the first battery assembly. The electric motor assembly receives electric power from the first battery assembly and the second battery assembly to propel the hull assembly through water during operation.
