Any abandoned vessel impounded under this part that remains unclaimed by the registered or documented owner, lien holder, or operator of record for more than ten working days after mailing of the notice required by § 200-42 may be sold at public auction by the state or county agency that took custody of the vessel. If the agency does not, or is unable to, sell the vessel at public auction, the agency, after giving public notice of intended disposition, may sell the vessel by negotiation, retain and use the vessel, donate the vessel to any other government agency, or dispose of the vessel as junk.
