A nitrogen compression system for a leakage test on a gas pipeline used for an engine according to the present invention includes: a nitrogen generator which is installed on a hull and generates nitrogen; a nitrogen storage tank which stores the nitrogen generated from the nitrogen generator; an air compressor which generates compressed air used to support starting of an engine for propelling the hull and supplies the compressed air to the engine; an air supplier which supplies air to the air compressor; and a first diverter valve which is installed on a first diverter pipeline connecting the air supplier, the nitrogen storage tank, and the air compressor and is controlled to supply any one of air and nitrogen to the air compressor. When the first diverter valve is controlled to supply nitrogen to the air compressor, compressed nitrogen compressed by the air compressor is used to purge a gas pipeline connected to the engine.

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.
