All ships engaged on international voyages shall keep on board
a record of navigational activities and incidents which are of
importance to safety of navigation and which must contain sufficient
detail to restore a complete record of the voyage, taking into
account the recommendations adopted by the Organization*. When
such information is not maintained in the ship's log-book, it
shall be maintained in another form approved by the Administration.
Each ship of 500 gross tonnage and above, engaged on international
voyages exceeding 48 hours, shall submit a daily report to its
company, as defined in regulation IX/1, which shall retain it
and all subsequent daily reports for the duration of the voyage.
Daily reports may be transmitted by any means, provided that they
are transmitted to the company as soon as practicable after determination
of the position named in the report. Automated reporting systems
may be used, provided that they include a recording function of
their transmission and that those functions and interfaces with
position-fixing equipment are subjected to regular verification
by the ship's master. The report shall contain the following:
ship's course and speed; and
details of any external or internal conditions that are affecting
the ship's voyage or the normal safe operation of the ship.
