Be careful who you get to service your mooring as some of the mooring contractors are not approved by MAST and this can cause some drama's if the mooring is in the incorrect position
This always REALLY annoys me. I asked MAST why they are approved and others not? Is there a training course? A set of standards or guidelines they complete there work to? Does MAST inspect their work every year? Nope!!
When it comes down to it (and this came straight from MAST), anyone can service a mooring as long as you keep invoices and take pictures and use the right gear.
