Take a look at this website. We ordered our USCG Documentation Plaque from them. Very high quality workmanship.This is the first time I will have a documented boat. How did you guys install your numbers. I've found some laser-etched stainless plates on the Web. I'm a little concerned about routing numbers on a laminate bulkhead.
This is how I did mine, it is fast and easy. Inside the port lazarette.Go to hardware and buy stick on numbers of the required size. Stick them to the hull - I put mine behind the settee cushion. Get some west systems epoxy and mix it up and paint over the numbers. Permanently attached, inexpensive and nice looking.
