Rotatable mounting for sail - has set of rings around mast to form connection for sail independent of relative rotation

摘要

The sail hoisting device forms the connection between the sail and the mast (4) and can rotate relative to the mast. It is formed by a set of freely rotating rings (2) around the mast. The edge of the sail is fixed to these. A fairing (3), improving the aerodynamic shape of the mast sail is fixed to the rings. It can be formed by a rigid or semi rigid sheath around the mast, with sufficient play, and fixed to the connector of the sail to the mast.
