Have you had a look through the list of surveyors provided by your insurance
There is a Marine
Surveyors Association but the insurance
company approved stamp may be essential for insurance purposes.
I had a less than fantastic experience with a cargo surveyor
some considerable time ago.
I used a local surveyor in Mooloolaba who'd been in business for a very long time for my insurance renewal and that worked out OK.
I just had a chat and he showed me a couple of surveys he'd done. Easy peasy.
