Hull for dual electric motor marine propulsion system

A watercraft hull for supporting and protecting a pair of propulsion units, the hull comprising:

• a shell having a longitudinal centerline and a stern section;
• a first recess formed at a first location offset from the centerline in a lower region of the stern section and open along lower and aft sides, the first recess configured to receive a first propulsion unit;
• a second recess formed at a second location offset from the centerline and symmetrical with the first recess about the centerline, the second recess being open along lower and aft sides and configured to receive a second propulsion unit;
• first and second openings through the shell, the first opening being operable to drivingly couple a first electric motor to the first propulsion unit and the second opening being operable to drivingly couple a second electric motor to the second propulsion unit;
• and
• first and second seal plates to seal the first and second openings when the watercraft is operated without the first and second propulsion units.

A boat hull comprising:

• a shell having an inboard cavity, an outboard surface and a longitudinal centerline extending from a bow region to a stem region;
• first and second recesses formed in the stem region of the shell at symmetrical locations with respect to the centerline for receiving and housing a respective propulsion unit, each recess being open along lower and aft sides and having side and upper walls oriented to direct water aft and towards the centerline during use;
• and
• first and second openings through the shell, the first opening being operable to drivingly couple a first electric motor housed inboard of the shell to a first propulsion unit housed within the first recess and the second opening being operable to drivingly couple a second electric motor housed inboard of the shell to a second propulsion unit housed within the second recess.
