This page is an index of ships by official number. Bear in mind that ships were often re-named so there may be several different names for the same vessel.
The source of the information is shown. This may be shipping and fishing registers, the Mercantile Navy List (MNL) or the Appropriation Books at the Registry of Shipping and Seamen (RSS), in which case the port or ports at which the ship was registered are shown.
Known crew list holdings are also shown with a link to show the documents that we know about.
The index also shows any book references which quote the official number, showing the author's name first.
Please see the CLIP data page for more details on sources, the abbreviations we have used, and acknowledgements.
Where we are aware that there is a Board of Trade enquiry report - a 'Wreck Report' - relating to the ship, we provide a link to the Southampton City Library site which has transcripts and images of these documents.
Where the ship's official number and/or port of registry is not shown (or is incorrect in the report), we have deduced it from the other information in the report, in which case we have shown it in square brackets like this:  of [London].
This data set is not yet complete and we are gradually adding to it. Many thanks to Sid Barnett for helping to compile this index
