Actually Dave, I didn't say "self certification", I said "self measuring".

A fine point, but important.

As stated by others, most measuring is redundant anyway. 95% of what we see are one-design classes. If you want to find cheating, look there for compliance. In most cases, you will not find it with a tape measure.

Major regattas should and do have compliance oversight. That is where it becomes important.

There are many ways to cheat and the measuring certificate would be low on the list if I were to try.
