Watercraft

A watercraft for operating on a body of water, the watercraft comprising:

• a hull;
• a deck supported by the hull;
• a propulsion system supported by the hull and configured to propel the watercraft;
• an electric motor operatively connected to the propulsion system to drive the propulsion system;
• a battery electrically connected to the electric motor for powering the electric motor;
• and
• at least one heat exchanger supported by the hull, the at least one heat exchanger at least partially extending out of the hull such that at least a portion of the at least one heat exchanger is in contact with the body of water,
• a first cooling circuit being in thermal communication with the at least one heat exchanger and at least one of the battery and the electric motor, the first cooling circuit being configured to circulate a heat exchange fluid therein,
• a second cooling circuit being in thermal communication with an other one of the at least one of the electric motor and the battery, the second cooling circuit being in fluid communication with the body of water during operation of the watercraft for circulating water from the body of water in the second cooling circuit during use.
