The bad news: Last night, I looked out into our cove to find that our 500 lbs. mooring system was not in its usual location ... in fact, nowhere to be seen.
The good news: Our boat is on the hard for the winter.
So, this mooring ball was installed with a 500 lbs mushroom in 2009. I found the ball still attached to the lighter top chain on nearby shoreline. I dragged it up on land but I haven't examined it closely yet because the sun was setting and it was raining. It looks like it failed at the first swivel at the bottom of the upper chain.
Is less than four years a short life for a mooring system in a protected cove in brackish water? I thought that I would pull, inspect, and or replace after 5 years being on the cautious side.
I have to forensically go back and examine what we put down there. But was there anything that we could have done incorrectly here?
This is similar to what we had in our setup:
