ǫrt ‘swiftly’: Syntactically, the adv. could modify bǫrðusk ‘they fought’ (so Finnur Jónsson in Skj B), or gengu (fyr borð) ‘went (overboard)’, or flaut ‘floated’. On grounds of word order the latter is favoured here, following Kock (NN §620). Kock (NN §2988C) compares fljóta hvatt ‘float briskly’ in KormǪ Lv 42/1-2V (Korm 61). The reading út ‘out’ in Kˣ and other mss gives equally good sense and is adopted in Hkr 1893-1901 and ÍF 27.
