Meaning of German "Haupt" (Captain) in 1748

The marriage record is from Evangelische Kirche Pferdsfeld (Germany)
BUT as it turns out what I believed to be "Haupt" is actually "Kauff"
so I don't need to worry about what "Captain" referred to!

Thanks!
Trevor

Hallo Trevor.-
I have been very carefully studying your mail incl. your attachment.
1.) The handwritten copy: Pls state from what church and which
place/country it was written.
2.) The meaning of "Captain" in those days can be a rank in the army,
in the german army it equals "Hauptmann" or "Rittmeister".
I dont know in which country you live, but doesnt the US-Army as well
as the british army have a rank named "Captain" ?
I have no idea since when the master of a seagoing vessel was named
Captain.
