The longevity of the 12 meter class is owed in no small part to  Lloyd’s scantling rules. They were strict and the boats were indeed inspected for compliance. These boats were overbuilt certainly by today’s standards and the result is that they are still here today.
In fact while I was building “Courageous” at Minneford’s Yacht yard one of my jobs was to co ordinate with Lloyds, as we were building the first ever aluminum 12 meter.
