Official Log Books and Record Books

The Merchant Shipping Act 1995 (s.77) (MSA 1995) requires UK Flagged ships to carry an official log book (OLB), except for:  

  • A ship belonging to a general lighthouse authority;  
  • A ship of less than 25 gross tons; or  
  • A pleasure yacht (private use)

Maritime and Coastguard Agency (MCA) official log books are provided free of charge to UK registered vessels and can be provided on a case-by-case basis to vessels registered with other Red Ensign Group (REG) member registers.

Revision of MCA official log books

The MCA is currently reviewing its official log books. To prevent excess amounts of OLBs circulating that may become out of date soon, we can only provide two OLBs per eligible vessel at this time. This does not apply to different types of OLBs, for example if you require both passenger and merchant OLBs you can order two of each per vessel.

We thank you for your understanding with this matter.

The Merchant Shipping (Official Log Books) Regulations 1981 specify:  

  • The particulars to be entered in official log books or annexes to them;
  • The persons who should make, sign and witness such entries;
  • The manner; the time of making them and the provision for their amendment or cancellation;  
  • And the manner, times and circumstances for the production and delivery of official log books to the appropriate superintendent or proper officer

The official log book contains pages for each type of entry required which ensures that the entries are completed in a way that complies with the regulations.
