PART 181—MANUFACTURER REQUIREMENTS
Subpart C—Identification of Boats

Sec. 181.29—Hull identification number display

Two identical hull identification numbers are required to be displayed on each boat hull.

(a) The primary hull identification number must be affixed—

(1) On boats with transoms, to the starboard outboard side of the transom within two inches of the top of the transom, gunwale, or hull/deck joint, whichever is lowest.

(2) On boats without transoms or on boats on which it would be impractical to use the transom, to the starboard outboard side of the hull, aft, within one foot of the stern and within two inches of the top of the hull side, gunwale or hull/deck joint, whichever is lowest.

(3) On catamarans and pontoon boats which have readily replaceable hulls, to the aft crossbeam within one foot of the starboard hull attachment.

(4) If the hull identification number would not be visible, because of rails, fittings, or other accessories, the number must be affixed as near as possible to the location specified in paragraph (a) of this section.

(b) The duplicate hull identification number must be affixed in an unexposed location on the interior of the boat or beneath a fitting or item of hardware.

(c) Each hull identification number must be carved, burned, stamped, embossed, molded, bonded, or otherwise permanently affixed to the boat so that alteration, removal, or replacement would be obvious. If the 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. A hull identification number must not be attached to parts of the boat that are removable.

(d) The characters of each hull identification number must be no less than one-fourth of an inch high.

Sec. 181.31—Manufacturer identification code assignment

(a) Each person required by Sec. 181.23 to affix hull identifications numbers must request a manufacturer identification code in writing from the Recreational Boating Product Assurance Division, 2100 Second Street SW., Washington, DC 20593-0001. The request must indicate the manufacturer’s name and U.S. address along with the general types and lengths of boats that will be manufactured.

(b) For boats manufactured outside of the jurisdiction of the United States, a U.S. importer must obtain a manufacturer identification code as required by paragraph (a) of this section. The request of an importer, as defined in Sec. 181.3 of this subpart, must indicate the importer’s name and U.S. address along with a list of the manufacturers, their addresses, and the general types and sizes of boats that will be imported. If a nation has a hull identification number system which has been accepted by the U.S. Coast Guard for the purpose of importing boats, it may be used by the importer instead of the one specified within this subpart. To request a list of those nations having such a numbering system, write to the Recreational Boating Product Assurance Division, 2100 Second Street SW., Washington, DC 20593-0001.

(c) Persons who are required to identify boats under Sec. 181.23(b) must obtain the required hull identification number from the State Boating Law Administrator of the State where the boat will be principally used, or, if the State Boating Law Administrator does not assign these numbers, from the Coast Guard District office in the area of principal use.

[CGD 79-013, 48 FR 40718, Sept. 9, 1983, as amended by CGD 88-052, 53 FR 25122, July 1, 1988; CGD 96-026, 61 FR 33669, June 28, 1996]

Sec. 181.33—Conditions for use of manufacturer identification codes

(a) No manufacturer or importer may sell or transfer a manufacturer identification code or use a manufacturer identification code that has been assigned to another.

(b) A manufacturer or importer who changes the business name or address must advise the Recreational Boating Product Assurance Division, 2100 Second Street SW., Washington, DC 20593-0001 of the change in writing.

[CGD 79-013, 48 FR 40718, Sept. 9, 1983, as amended by CGD 88-052, 53 FR 25122, July 1, 1988; CGD 96-026, 61 FR 33669, June 28, 1996]

Sec. 181.35—Removal of numbers

No person may remove or alter a number required by this subpart unless authorized by the Commandant, U.S. Coast Guard.
