Systems and methods to provide an exterior stringer system inflatable paddleboard. The exterior stringer system inflatable paddleboard maintains the benefits of a baseline inflatable paddleboard while providing increased strength, such as increased rigidity or stiffness. The exterior stringer system is positioned on the bottom surface of a baseline inflatable paddleboard. In one embodiment, the exterior stringer system is formed by a set of longitudinal stringers positioned on opposite sides of an inflatable paddleboard and a set of transverse stringers arranged in an X configuration between the longitudinal stringers.

A surfboard with an electric drive (2), a battery for the electric drive (2), said battery being arranged in a battery housing (3), a first recess (4) for the battery housing (3), and a handle (5) on the battery housing (3), wherein the handle (5) is designed as a bracket handle which is mounted pivotably around a respective centre of rotation (21) at each of the handle ends on opposite sides (6) of the battery housing (3), and in each case a lug (9) protrudes from the base side of the recess below the centres of rotation (21) inside the first recess (4), and at each handle end of the bracket handle a second projection (33) is formed, which has a curved edge (34) and which rests on the lug, and a distance between a contact point of the curved edge (34) with the lug (9).
