We all recognise the importance of maintaining our boat, in order to ensure that She remains safe and sea worthy. However, one of the most important things in keeping the vessel safe, are it’s berthing/ mooring chains and lines.
A number of factors affect the service life of a mooring chain. This includes not only physical wear, but also galvanic or electrolytic corrosion. Because of these, mooring lines and chains are corroding at rapid rates.
In order to prevent claims arising from vessels breaking mooring, we would highly recommend that both the mooring lines and chains are checked on a regular basis to ensure that they are not corroding or wearing to a point that they will fail.
Topsail Insurance recommend, and Lloyd’s Insurer’s would require, that moorings are professionally installed, serviced annually and certified for size of vessel by the mooring company when moored at one location for any period in excess of 30 day.
The chain shackles (in the image) were only 18 months old. Maintenance of the vessels mooring chains and lines is the boat owner’s/ Skipper’s responsibility.
