A watercraft includes a hull structure, a deck structure, and a propulsion system. The hull structure includes at least one hull each defining an interior. The deck structure is mounted to the hull structure. The propulsion system is adapted for moving the watercraft within a body of water, and includes an electric motor and an energy storage device coupled to the electric motor. The electric motor and the energy storage device are positioned adjacent one another within an area including at least one of the interior of the at least one hull.

A cooling system for a boat includes at least one cooler located inside a hull of the boat and closed to the exterior of the hull. The cooler is configured for the exchange of thermal energy between a flow of coolant in the at least one cooler and a fluid flow outside of the hull via a hull wall positioned between the flow of coolant and the fluid flow. One or more coolant passages extend from the at least one cooler defining at least one coolant loop. The one or more coolant passages are configured to deliver the flow of coolant from the at least one cooler to one or more components located along the at least one coolant loop to cool the one or more components, and return the flow of coolant to the at least one cooler.
