An Etymological Dictionary of the German Language/Annotated/Büse
Büse, feminine, ‘herring-boat,’ not from Middle High German buze, Old High German buzo (z for ts), but from the equivalent Dutch buis, to which Old Icelandic búza,. Anglo-Saxon bûtse (in bûtsecearlas), English buss, also correspond. There are similar words in Romance — Middle Latin buza, bussa, Old French busse, buce. The origin of the cognates is probably not to be sought for in Teutonic; the source whence they were borrowed is uncertain.
