Section 53

The Port Master, an authorised representative of the Port Master, any officer of the Authority authorised by the Authority or any police officer may go on board any vessel in the port whenever he or she suspects that any offence against this Part has been or is about to be committed in any vessel, or whenever he or she considers it is necessary for him or her to do so in the discharge of any duty imposed by this Part or otherwise by law.

Any master of such vessel who, without lawful excuse, refuses to allow the Port Master or the other persons referred to in subsection (1) to enter the vessel shall be guilty of an offence and shall be liable on conviction for each offence to a fine not exceeding $1,000.
