This 3 inch set of numbers and letters comply with Canadian boat identification rules. Four sets of each number and letter are included except for: only two each of A,B,8 and 5; only 4 in total of the letter O and number 0 combined; only 4 in total of the numbers 6 and 9 combined; and no number 1 . 16 dashes (-) are also included. This shaded number/letter set is black and white and is marine grade. I currently use this coloring on a black boat, and the decals show up perfectly. A 6”x23” protective boat bumper is also available. Airdrie.
