Abstract: What is disclosed is a supporting frame for a hand-supported sailing rig in which a mast with a middle section curved in a preferably circular arc-shaped manner and merging into two end portions is formed, the radii of curvature of said end portions being smaller than the one of the middle section. The supporting frame has supporting means for supporting the rig at the body of the user. The middle section is preferably provided with a joint device which allows the arrangement of the supporting components in the folded state in a parallel orientation towards each other.
