What You May Find in the Records Great Britain has long been known for its maritime prowess in both military and commercial spheres. The certificates and other documents included in this database were issued to merchant seamen who qualified as masters or mates aboard merchant ships. Records include certificates of competency, certificates of service, examination applications, and other documents. Forms vary, but they may include the following details: name certificate number birth date birthplace issue port issue date address examination date history of service (dates, vessels, occupations, years in service) Some of the information is included on the back of the certificates, and some documents in a seaman’s folder have not been indexed, so when you find a record, use the arrows to browse surrounding documents to make sure you see all the records available. You may want to browse through an entire roll since the original folders were sometimes filed in random order. -- Nivard Ovington in Cornwall (UK)
