byrðingr, búza (m., f.) ‘freighter, merchant-ship’: Both terms denote large merchant-ships. While the first is an indigenous Old Norse word (cf. borð and byrði ‘ship’s side’), the second is a loanword (< MLG būtze, būse < MLat. buza, bucia ‘ship for transporting cargo’; AEW: búza, bússa). Neither ship-heiti occurs in skaldic verse, but both terms are found in the rímur (Finnur Jónsson 1926-8: byrðingr; búza). See Falk (1912, 110-12). It is possible that Skuldelev 3, a fourteen-metre long coastal trader with a carrying capacity of 4-5 tons, was a byrðingr (Crumlin-Pedersen 2010, 110).
