Failure to properly display boat registration numbers (OR#’s) and have current registration decals is a Class D Violation ($110 fine).
*If your OR Numbers have 3 letters, group them next to each other (as shown below). Oregon Revised Statute (OAR 250-010-0040).
US Coast Guard Documented Vessels
Documented vessels moored in Oregon waters are also required to register the vessel with the Marine Board and affix the expiration stickers (decals) on the port and starboard sides of the boat at the stern.
A Boat Documentation plate displays the identification number assigned to boats by the United States Coast Guard. The Coast Guard number marking requirement in 46 C.F.R. § 67.121 states: "The official number of the vessel, preceded by the abbreviation "NO." must be marked in block-type Arabic numerals not less than three inches in height on some clearly visible interior structural part of the hull. The number must be permanently affixed to the vessel so that alteration, removal, or replacement would be obvious. If the official number is on a separate plate, the plate must be fastened in such a manner that its removal would normally cause some scarring of or damage to the surrounding hull area." Permanent installation would therefore require both screws and adhesive. When you document your boat with the USCG, place the name of your boat and the hailing port (the home port of the vessel owner by city and state) on the transom.
