1. A mounting structure for mounting a propulsion unit to a hull of a floating structure, the mounting structure comprising:
a first mounting surface, and
a sealed portion provided on the first mounting surface for sealing the propulsion unit to the hull,
wherein the first mounting surface is further provided with:
a pivot point provided at an edge or in the vicinity of an edge of the first mounting surface and outside the sealed portion, and
at least two first protrusions spaced from each other on the first mounting surface, wherein each of the first protrusions includes a surface at least on a side of the first protrusion facing away from the pivot point, said surface is formed at least in a direction perpendicular to the first mounting surface dependent of a distance between the pivot point and the surface such that the first protrusion provided in a cylindrical cavity formed in a counterpart is configured to guide a mutual tilting movement of the cylindrical cavity and the first protrusion, when the mounting structure and, thus, the first protrusions are tilted with respect to the cylindrical cavities about the pivot point.
