81B. (1) Any officer appointed under section 81 has reason to believe that an inland ship has been or is being used in contravention of the provisions of sub-section (1) of section 18 or without the certificate of survey required by sub-section (1) of section 9 or without the permit required by sub-section (3) of section 9, seize and detain the inland ship. (2) Notwithstanding anything contained in sub-section (1), where any such officer or person has reason to believe that an inland ship has been or is being used without the certificate of survey required by sub-section (3) of section 9, he may, instead of seizing the inland ship, seize the certificate of registration of the ship, certificate of competency of master and driver and shall issue an acknowledgement in respect thereof. (3) Where no owner of a detained inland ship is found after a reasonable enquiry, the ship may be auctioned in public in such manner as may be prescribed or taken in to custody in favour of the Government, in order to stop the non-compliance.
