Research guide C12: The Merchant Navy: Ship registration and Custom House records


This guide outlines the history of ship registration in Britain, from the mid 17th century until 1857, when the official Mercantile Navy List was first published. 

It also explains where to find transcripts of ship registers from Custom Houses throughout the British Isles.

Before 1786, there were no central government records of ship registration, although ships began to be registered around the middle of the 17th century.

  • 1661: Foreign-built ships were required to register with Custom Houses in order to obtain the same trading privileges as British-built ships.
  • 1695: British-built ships also had to register before trading to or from the colonies. This was later extended to ships importing wool from Ireland.
  • 1786: The Merchant Shipping Act (1786) required all British ships of more than 15 tons to register with Customs in their home port. A copy, known as a transcript of each entry was sent to the Custom House in London or Edinburgh.
  • 1814: Fire in the London Custom House destroyed all the early transcripts sent from other ports. However, registration books for the Port of London itself survive, as do some local records kept by Custom Houses at other ports (see below).
  • 1835: The official method of calculating tonnage was revised; for steamships, engine-room space was deducted.
  • 1854: The Merchant Shipping Act (1854) introduced official numbers for all newly-registered ships and further revised calculations of tonnage.
  • 1855: New measurement became compulsory for any ship re-registered or transferred to a different registry.
  • 1857: The first generally-available Mercantile Navy List was published, covering all ships registered in Britain or at Empire (subsequently Commonwealth) ports, and was issued each year until 1976.
