Now (one) is to tell about Búi. (It) blew slowly for them (ie they got very light winds) and reached (the) Orkneys (Seal-Islands) late in the autumn.

Búi sagði af hið ljósasta "og vildi eg þiggja veturvist með yður herra."
Búi said (rattled off? said of (it, himself), I´m not sure what “af” is doing here) the most-plain (answer)  “and I would-want to receive a winter-stay (winter-lodging) with you, lord.”

Jarl segir: "Fylgd góð mun í þér. Skaltu víst vera með oss í vetur ef þú vilt."
(The) earl says: “Good support will (be) in you (you will be useful to us?). You shall certainly be (stay) with us this winter if you want.”

Búi was (stayed) with the-earl’s guard (security-forces) during the-winter. Earl Einar had much trouble during the winter.

Búi was the most-fearless in all trials-of-courage. But during the-spring when that ship*

Jarl segir: "Hitt þykir mér ráðlegra Búi að þú dveljist með oss. Höfum vér
(The) earl says: “That (other option) seems to me more-advisable, that you remain with us. We (royal “we” or the court as a whole) have

therewith other honours if you want to be (stay) here.”

Búi þakkaði jarli með fögrum orðum en kveðst vilja til Noregs. Jarl kvað svo vera skyldu.
Búi thanked (the) earl with fair words but declared-of-himself to want (to go) to Norway. (The) earl declared (it) should be so.

Eftir það sigldu þeir til Noregs og komu að norðarlega.
After that they sailed to Norway and came upon (approached) (it) far-to-the-north.
