Tackful's forestay fitting broke on our way home after racing on Saturday. Fortunately the jib was up and held the mast in place until I could rig additional support. The forestay tang broke where it joins the well-supported base (see photo on fleet e-mail), which must be the point where metal fatigue cause by 25 years of hard sailing is concentrated. I suppose that a stress crack developed, after which internal corrosion led to eventual failure. Not all our boats have a forestay fitting with an extended tang like Tackful's, but those that do may merit close examination.
