Note 260 — XXXVII THE DUTIES, ACTIVITIES, AND AMUSEMENTS OF THE ROYAL GUARDSMEN
Laurence Marcellus Larson translation
The prow-boar (rôðrgoltr) was not a beak but apparently some device fastened to the prow which served much the same purpose, namely to run down and sink an opposing ship. See the Sorö edition, 395-396; Falk, Altnordische Waffenkunde, 198-199.
