1. A watercraft comprising:
a hull;
a deck disposed above the hull;
an electric propulsion system including:
a battery disposed in a rear portion of the watercraft at least partially between the hull and the deck, the battery having an elongated shape extending along a longitudinal direction of the watercraft, and
an electric motor electrically connected the battery;
an opening defined at least in part by at least one of a stern end portion of the hull and a stern end portion of the deck, the opening providing access to a space between the hull and the deck, the opening being sized to permit the passage of the battery therethrough; and
a rear module extending at least substantially vertically and selectively removable from at least one of the stern end portion of the hull and the stern end portion of the deck, the rear module selectively closing the opening, the rear module defining a stern-side surface of the watercraft,
the rear module, the battery, the deck, and the hull being arranged such that the battery is selectively removable by translating the battery longitudinally sternward and substantially parallel to the deck and out through the opening when the rear module is removed from the watercraft.
