Wear and tear can cause moorings to deteriorate very quickly. They can be moved out of position by severe weather and corrosion and abrasion can reduce the condition of the mooring significantly.

Mooring licence holders are required to maintain their moorings in the appointed place and in good order and condition.

It is also compulsory to have every part of the mooring lifted and inspected at least once every two years, however it is recommended that this occurs more frequently.
