Records for merchant seamen

[Karen Norwillo]

Is there a central resource for information about merchant seamen and sailors in Sweden in the late 1700's into the 1800's? Especially interested in the area around Blekinge län.I am hoping to find more about Petter Hagelund from Hallersboda who was identified as a merchant skipper in the household rolls up to 1812. I lose track of him after her moves away after the death of his wife in 1812. GID:1763.52.42200, 1763.22.90100, 1763.5.48600, 1763.6.79400. This is the last place I found him. Petter and his wife Kaisa were my 4th great-grandparents.
