Doc. Numbers
Don,Its nice to display your documentation numbers on a plaque and I agree with the other responses as to how to do it but, I would inform you that documentation numbers, by law, must be affixed to the boat in such a way that removal would leave an imprint of the numbers. When I did my 28 MKII I used black stick on numbers which I stuck to the hull --- this must be in an area that is easily found, I used the storage area under the setee. After the numbers are fixed you coat them with clear epoxy the liquid stuff that they poor on tables. I brushed it on. This meets all the law requirements and if you have your boat Coast Guard inspected they will check. I also have a nice plaque with the boat name and numbers mounted on a forward bulkhead.
