Wake boats having battery systems and electric propulsion devices for wake boats

A marine vessel comprising:

• a hull extending from a stern to a bow in a longitudinal direction, from a port side to a starboard side in a lateral direction which is perpendicular to the longitudinal direction, and from a top to a bottom in an axial direction which is perpendicular to the longitudinal direction and perpendicular to the axial direction;
• an electric motor and a propulsor, wherein the electric motor is configured to operate the propulsor for generating a propulsive force for propelling the marine vessel in water;
• port and starboard rear ballast cavities configured to take on ballast water for modifying a wake produced by the marine vessel in the water;
• and
• port and starboard battery banks which provide battery power to the electric motor, wherein the port and starboard battery banks are located axially above the port and starboard rear ballast cavities, respectively, wherein the marine vessel has a center of buoyancy and wherein the port and starboard battery banks are located longitudinally between the stern and the center of buoyancy.

• and
• port and starboard decks located over the port and starboard rear ballast cavities in the axial direction such that port and starboard battery compartments are located axially between the port and starboard decks and the port and starboard ballast cavities, with the hatch therebetween, wherein the port and starboard battery banks, when installed in the port and starboard battery compartments have a length, a width and a height, and wherein the height is less than a width of the hatch in the lateral direction and the length and width is greater than the width of the hatch in the lateral direction such that the port and starboard battery banks are rotated when in port and starboard battery compartments relative to before entering the hatch.
