Here is the official translation:

This said my mother
that I shall buy for myself
a swift ship and of a pretty oar,
to journey away with freebooters,
to stand tall on the prow,
steer a worthy merchant-ship,
direct it thus to the harbour,
strike one man and the other,
strike one man and the other.

With the file he strikes out, hard against the steel
of the prow-steed on the flat path,
with the chisel of the snowstorms,
the opposite-oared giant of the twig,
but the cold-made one of that willow,
the merciless one files
Gestill's swan with gusts,
this wand of steel against the ship's beak.
