Abstract: A surfboard including a surfboard body and having an upper surface and a bottom surface, an upwardly open cavity formed in the upper surface, an electric drive for propelling the surfboard, a battery housing having an upper face and being connected with the electric drive for supplying electrical energy, the upper face having a recess extending between opposite side faces of the battery housing, the battery housing being removably received in the cavity. A bracket handle with a central portion and opposite side portions defining arms pivotally mounted to the battery housing to allow turning of the bracket handle between a carrying position for carrying the battery housing when removed from the cavity and a second position wherein the central portion is nested within the recess. The battery housing having a latching portion in releasable engagement with the central portion when nested within the recess.

Abstract: A modular electrically motorized watercraft may include a hull module and a driveline system. The driveline system may include one or more electric power modules and two or more driveline modules. The two or more driveline modules may be configured to be mounted to an underside of the hull module. The modules may constitute independent sub-assemblies that form the watercraft when assembled together.

Abstract: The disclosure relates to a powered watercraft (100) comprising: a host device (102), the host device comprising at least one host identifier device (104), a driveline (106) comprising a propulsion module (108) and a battery module (110), the battery module being configured to power the propulsion module, the driveline comprising an identifying device (112) and a control unit (114), the control unit being configured to adjust at least one driveline parameter, wherein the driveline is configured to be received in the host device, wherein the identifying device is configured to read the at least one host identifier device to obtain at least one host identifier of the host device, wherein the control unit is configured to receive the at least one host device identifier from the identifying device, to obtain at least one corresponding host device characteristic based on the host device identifier; and to adjust the at least one driveline parameter based on the at least one corresponding host device characteristic
