With respect, subsection (b) doesn't say what the witness just described.
In this case, the enforcement officer could direct the vessel to moor, anchor, or remain there for any reasonable period they may specify. The change I'm trying to make here is to say that, if the enforcement officer has reasonable grounds to believe that an offence under this act has been committed, then they must act. They do have a range of pieces, but some of them absolutely could include a vessel that is already tied up to a dock having to remain there and cannot then vamoose and leave the marina owner having to pay the bill, for example.
The discretion is built in there, but the action, if my amendment passed, would not be.
