According to the references that I have seen, the other end is supposed to be in Brittany. Since Brittany is still at least two months away, it still links to Ardoris. I personally think that it would be cool to have a Brittany boat reach west HV and an Ardoris boat reach Kingsport. Without looking at sotamap, there's maybe six in Owl's Head, and six in Kingsport. So a dozen NPC/PRT row lots in HV. This will probably change when they get around to rebuilding PRTs.
