With Matilda Emilie sold, I left the regular survey of the mooring gear until I had some time over the Christmas break.
While the shackles were in quite good condition and came apart relatively easily, despite being submerged for most of the time, the wear and wasting was a concern as shown below.
These have only been in use to two seasons as I bought all new gear when Matilda was moved to her mooring at the beginning of 2013. She's not a heavy boat at 21 feet so I presume the wear must be down to the constant abrasion or maybe inferior materials.
