Our high quality vinyl Boat Registration Numbers are produced according to required government specifications. Choose a main vinyl color and a back drop-shadow color from our wide selection, but keep in mind that it is mandatory for the main vinyl color to contrast with the background color of the boat. Vinyl Boat Registration Numbers are 3" tall and sold in pairs to clearly label both sides of your boat. Choose a font style from our 4 available options: Helvetica Bold, Chicago Style DNA, Clarendon Bold, or ITC Machine. These vinyl numbers are very resilient and can be expected to last up to 8-10 years.
