Here in Michigan, the law was amended in 2002 and now states:.. The
operator of the vessel shall do the following upon the request of the
peace officer:..... If the vessel does not bear a decal described in
section 80166a or an equivalent decal issued by or on behalf of another
state, submit to a reasonable inspection and test....." The decal
referenced is the VSC decal, from the Auxiliary or the Power Squadron,
and now used by all DNR and County marine patrols (yes, they all use
the IDENTICAL decal!!).

So, if you have a current decal and there is no cause, you will not be
inspected on Michigan waters by different agencies. (Note: this is
state law, and the CG is not subject to it, so they can inspect as they
please).

AFAIK, Michigan is the only state that codified benefits to receiving a
Vessel Safety Check and receiving a decal when all requirements are
met.
