57. Proof of position of vessel

This section and section 58 apply for the purpose of proving in any legal proceedings the position of any vessel at any particular time or when any particular event occurred.

Unless the contrary is proved, a document purporting to be an entry in the log book of an enforcement vessel certified by any enforcement officer is deemed to be such an entry.

Unless in any legal proceedings the court otherwise directs, a document which is referred to in subsection (2) shall be received in evidence without the person who certified the entry or who gave the certificate having to be called as a witness.
