A personal watercraft including a hull and at least two pontoons repositionably attached to the hull with at least one pontoon attached proximate the starboard side and at least one pontoon attached proximate the port side. In this manner a bolt element with a spherical head can be manufactured in an extremely favourable manner price-wise and it can be ensured that the spherical head has no burr which would lead to the wearing of the socket provided in operation which slides on the spherical head. A second nitride epitaxial structure is on the common nitride epitaxial layer of the first nitride epitaxial structure. In addition, when a channel width is longer than a channel length, the area of the channel formation region can be increased.
