Methods of recording should be permanent and may be:

Page numbers

Each page of the ship’s log-book should have a page number printed on it.


Handwritten records, which need correction should be rewritten after crossing out the incorrect version.


The times used in automatic and permanent recording facilities should be synchronized by using a common clock.


Electronically or mechanically input records should be protected by means to prevent them from being deleted, destroyed or overwritten.


Ships should keep records for as long as their flag state requires, provided that it is not less than one year.
