[Rhodes22-list] CDI Furler Wire Halyard Snapped - What's at the top?

[ROGER PIHLAJA]

Peter,

S/V Silver Heels experienced scenario #1 from my previous post.  If Allyn’s boat experienced the same issue; then, we may have a problem area.  We might want to warn the whole Rhodes list to inspect the toggle joints on the top of their forestays.  From your U-Tube video, your failure looked like a chloride stress cracking fatigue failure.  Such failures are common with 300 series stainless steel alloys in a salt water environment.  They can be early detected by dye penetrant, magnaflux, or ultrasonic testing.  Dye penetrant would be the easiest for the average boat owner.  All boats that sail on salt water would be subject to this issue.
