Section 18

If any vessel is detained under section 17 and the vessel proceeds to sea before it is released by the competent authority, the master of the vessel, and also the owner thereof and any person who sends the vessel to sea, if that owner or person is party or privy to the act of sending the vessel to sea, shall be guilty of an offence and shall be liable on conviction to a fine not exceeding $10,000 or to imprisonment for a term not exceeding 2 years or to both.

Any person authorised under this Act to detain a vessel may, if he thinks it necessary, place a police guard on board.
