The original thread is three years old so the original issue was dealt with (I would hope). In most cases the USCG does not override state rules if the requirement is over and above their own, which is the reason why each state has different regs for stuff like the minimum age for wearing life jackets and who has to take a boating safety course.
Boaters are responsible for knowing the regulations in the state(s) in which they boat.
