A boat requiring numbering by this state shall be registered with the department. The application shall be accompanied by a fee to be set by rules promulgated by the Game, Fish and Parks Commission pursuant to chapter 1-26. The new owner of the boat shall present a manufacturer's statement of origin or assigned certificate of title if a title has been previously issued for the large boat, or if no title is required, the ownership document issued by that jurisdiction; a bill of sale containing a complete description of the large boat; the purchaser's name and address; the previous owner's name and address; the full purchase price as defined by this chapter and how computed; the trade-in allowance and description of the trade, if any; and any other relevant information the department may require to the county treasurer in the county of the owner's residence or if the new owner is a nonresident to any county treasurer. If a person intentionally falsifies information on the certificate, the person is guilty of a Class 6 felony.
