Abstract

The present invention provides a sail safety release system 1 for sailing vessels, such as yachts, to release a sail of the vessel when the sail is overloaded. The system comprises a link (L1, Fig 3) between the sail S at one end and a control line C leading back to the boat for restraining the sail at the other end. The link is configured to act as a mechanical fuse that will break apart releasing the control line's initial restraint on the sail, if the load applied to the sail and pulling on the control line exceeds a predetermined safe threshold level. A parallel tether link (L2, Fig 3) may be provided, in parallel to the mechanical fuse, to provide a secondary restraint on the sail, once the mechanical fuse has broken, that is less restrictive than the initial restraint on the sail.
