Yep, even spray clear polyurethane over it....

Thanks for the reply guys. I was on the CG web site too and got the "law" but again, I want to do something cool yet legal. After reading these replies I am leaning toward getting an anodized aluminum plate and having the NO. and numbers engraved in it leaving behind a shinny surface of engraved area. That then will be riveted to the bulkhead alongside one of the engines. I want the next owner to be able to remove it without really scaring up the boat.

Yep, even spraying clear polyurethane over the vinyl shoiuld work. Scarring would occur should it be removed. But the only test would be to actually have Coast Guard check it....

Decided to get some aluminum deck plate, have it powder coated to match the bezels and CNC the numbers in it.

I am Having Dana Marine mill the numbers in a piece of Billet, and then I am going to have the area surrounding the letters / numbers painted to match the battery covers. The numbers / letters will be polished.

I have had this boat for two seasons and have yet to be checked yet. I have had the local law enforcement agency look at the back of the boat for name and hailing port, but they have never asked to see the I.D. numbers.
