Display of OR Number and Decals
OR Number and Decals
Proper Display of a Boat Number is Required
The proper display of a boat number is required for identification purposes. Improper display of number is a very common reason for being stopped by marine enforcement officers.
Figure 1
The numbers and letters must be 3 inches tall, vertical (not slanted), plain (not script or varying in thickness), and any border outline or shadowing must be disregarded in determining the height or color contrast. The number's color should be in contrast with the boat hull's color so as to be legible at a distance. No other number or letters can be displayed nearby if they will interfere with the identification of the vessel by its state number.
Figure 2
The validation decals, issued by the State Marine Board and renewed every two years, must be placed on each side of the boat, 3 inches aft (towards the back) and in line with the registration numbers as shown in figures 1 and 2. Only the current decals shall be displayed.  The Marine Board only furnishes the registration expiration decals.  You may purchase the OR numbers at your local hardware store or marina dealer.
For Documented Vessels, decals need to be affixed on both the PORT and STARBOARD sides of the hull at the STERN.  Click here for an example.
