I am not sure if this will be of any help, but I have the same issue with an ancestor from the 1840s who was a sailmaker on sailing ships
If you are in UK, then I think it helps if you know whether Royal Navy or Merchant Navy.
Ancestry seem to have some docoments of people who were apprenticed in the Merchant Navy in early 19th century
I looked at CLIP on crewlist.org.uk and rmg.co.uk (Greenich Maritime Museum) and National Archives in Kew, but I just got confused
Different resources seem to be held in different places, and it depends on the dates, and for some, you need to know not only the name of the Merchant ship but also its unique registration number.
The person in my tree is from the Shetland Isles and I am hoping that the Shetland Archives may have some information.
Good luck. I will be very interested to see if you get a better informed response than mine from someone with experience searching.
