A self-supporting rotary rigging and, more specifically, a rigging that has a circular platform adjacent to the deck of the vessel, which makes it possible to control the rotation of the rigging and to install rotary stays and shrouds, which assists in stabilizing the rigging. The rigging is characterized by the existence of a small common boom securely joined to the base platform and to which are fastened the backstay and forestay, all the aforesaid making the rigging very secure and enabling the backstay and forestay to be capable of downward movement. There is a base crosstree, likewise securely connected to the platform, perpendicular to the stays, and to the end thereof are fastened the shrouds, enabling the later to work at a suitable angle. In addition, there is a tunnel across the lower part of the mast, which allows passage from one side of the rigging to the other.
