These are the bow chock ends of Orinoco's pendants. Note the chafe gear still in place, and munched, on one of them. I suspect the other one was lost to the sea. Good things can happen to well prepared people.
If you can it may be a good idea to watch your chocks and pendants interact when there is a blow. It may be a good indicator of how they will survive in a storm. These pendants would likely show virtually no signs of chafe until a storm, which for this owner, makes it tough to isolate what causes a failure.
Our boat was just 70' from where Orinoco was moored and suffered no chafe what so ever. She uses dual unequal length Yale Polydyne II mooring pendants. Ours survived without any noticeable chafe yet both of Orinoco's pendants parted and she drifted off...
It should be noted that these three strand pendant were only about three weeks old at the time of failure. They both chafed equally, and both apparently failed at near the same time, because they are equal length they will also chafe equally as fast..
