Sorry I have switched back to John, Could you call a Master of a boat a seaman 
Yes

1901 census has John W. Thomson age 50 and married born Harwich, Essex - Master of 'Emma of Plymouth' with crew of one James Larsen. They are moored in Salcombe. Can only see him on later census though.
Excellent news. Essex-born is looking good!
