1. Introduction

A range of abbreviations were used by the Registrar General of Shipping and Seamen (RGSS) when entering details of voyages etc. in the various registers of service for seamen, masters, mates, engineers and fishing officers. The lists below, although not complete, do contain a lot of the abbreviations commonly used which offer a means to translating most of those not included.

It should be noted that no key has been found for the 'Port Rotation Numbers' used in many of the pre-20th Century registers of seamen's service. A key to Ships' Official Numbers may be found in class BT 336.
