Hi Ron and Mike,
Ron Holtkamp (he was at Homer's) had his depart
from his engine a few years ago. He was over the
Mississippi (i think that's the one) and had to
auto onto a levee beside the river. The only one I
have heard of though. But that doesn't mean there
have not been any. There have been many chain
master links come off, (including ours)  but  we
didn't hear about them either.

There was also a failure of the main drive pulley at the top of the engine last week. Apparently this ship had suffered an upper engine clevis break some time back. The pulley had been inspected after the event and put back in service. Tom Smith speculated that the pulley may have suffered some unseen damage and ultimately failed itself. Tom showed me the pulley and the entire bottom of the pulley inside the bolt spot faces had sheared out. A very interesting failure mode! I believe this is an isolated incident, I had never heard of this type of failure before.
