A fuel reservoir is disposed in the compartment and extends longitudinally over the keel. The fuel reservoir has an external hollowed portion. At least one battery is at least partially disposed in the external hollowed portion. ## Claims ### Claim 1 A watercraft comprising: a hull having a keel; a deck supported by the hull; a compartment defined between the hull and the deck; a fuel reservoir disposed in the compartment and extending longitudinally over the keel, the fuel reservoir comprising an external hollowed portion; and, at least one battery at least partially disposed in the hollowed portion; wherein the external hollowed portion is a recess extending laterally inward from a lateral wall of the fuel reservoir; wherein the recess is disposed longitudinally centrally along the lateral wall of the fuel reservoir. ### Claim 2 (depends on 1) The watercraft of claim 1 wherein the at least one battery is disposed in the recess and laterally inwardly from the lateral wall. ### Claim 3 (depends on 1) The watercraft of claim 1, wherein the fuel reservoir is laterally centered about the keel. ### Claim 4 (depends on 1) The watercraft of claim 1, wherein: the fuel reservoir comprises a bottom left side surface and a bottom right side surface; and the bottom left and right side surfaces define a generally V-shape. ### Claim 5 (depends on 4) The watercraft of claim 4, wherein: the hull is a V-shaped hull; and the generally V-shape of the fuel reservoir is angled substantially similar to the V-shaped hull such that the fuel reservoir lays flat on the hull. ### Claim 6 (depends on 1) The watercraft of claim 1, further comprising: a plurality of fasteners fastening the keel to a bottom surface of a hull body of the hull; and wherein a bottom surface of the fuel reservoir defines a longitudinally extending groove, the groove is sized for avoiding contact between the fasteners and the bottom surface of the fuel reservoir. ### Claim 7 (depends on 1) The watercraft of claim 1, further comprising a hatch door; wherein: the deck defines a hatch disposed above the at least one battery; and the hatch door is configured to selectively close the hatch. ### Claim 8 (depends on 1) The watercraft of claim 1, wherein: a longitudinal distance between a rear face of the fuel reservoir and a rear end of the hull is less than a longitudinal distance between a front face of the fuel reservoir and a front end of the hull. ### Claim 9 (depends on 1) The watercraft of claim 1, wherein the fuel reservoir is disposed laterally centrally in the hull. ### Claim 10 (depends on 1) The watercraft of claim 1, wherein: the at least one battery comprises two batteries; and the two batteries are disposed within the external hollowed portion of the fuel reservoir. ### Claim 11 (depends on 10) The watercraft of claim 10, wherein one of the two batteries is disposed in front of another one of the two batteries. ### Claim 12 (depends on 1) The watercraft of claim 1, further comprising a power cable, the power cable connected to a terminal of the at least one battery and extending along a top of the fuel reservoir. ### Claim 13 (depends on 1) The watercraft of claim 1, further comprising at least one of: an above-deck side compartment and an above-deck rear compartment. ### Claim 14 (depends on 1) The watercraft of claim 1, wherein: the hull has a first pontoon, a second pontoon, and a central portion disposed laterally between the first and second pontoons; the keel is a first keel of the first pontoon; the second pontoon has a second keel; the central portion has a third keel; the compartment is a first compartment defined between the first pontoon and the deck; the fuel reservoir is a first reservoir disposed in the first compartment; and the at least one battery is at least one first battery disposed in the first compartment. ### Claim 15 (depends on 14) The watercraft of claim 14, wherein a second compartment is defined between the second pontoon and the deck; and the watercraft further comprises: a second fuel reservoir disposed in the second compartment and extending longitudinally over the second keel, the second fuel reservoir comprising a second external hollowed portion; and at least one second battery at least partially disposed in the second external hollowed portion. ### Claim 16 (depends on 15) The watercraft of claim 15, wherein: the at least one first battery comprises two first batteries; and the at least one second battery comprises two second batteries. ### Claim 17 (depends on 16) The watercraft of claim 16, further comprising a first hatch door and a second hatch door, wherein: the deck defines a first hatch disposed above the two first batteries and a second hatch disposed above the two second batteries; the first hatch door being configured to selectively closes the first hatch; and the second hatch door being configured to selectively closes the second hatch. ### Claim 18 A watercraft comprising: a hull having a keel; a deck supported by the hull; a compartment defined between the hull and the deck; a fuel reservoir disposed in the compartment and extending longitudinally over the keel, the fuel reservoir comprising an external hollowed portion; at least one battery at least partially disposed in the hollowed portion; and a support frame disposed in the external hollowed portion; wherein the at least one battery is connected to the support frame.
