    Multiple answers.
    
    1. We don't know how accurately they were able to  navigate. But,
    whenever Polaris is visible, latitude sailing will get you home. All
    they would need to find Iceland, say, would be a Polaris altitude. The
    same for the Faroes, Shetlands, etc.
    
    2. Morison believes they may have used mirages to sail toward islands
    way beyond the horizon. Apparently these are both common and stable at
    higher latitudes. I have seen mirages on the Maine coast many times,
    but usually only a few feet higher than the reality.
    
    But, I remember in Cape Cod Bay at dawn seeing the City of Boston high
    in the air. It stayed in place for at least two hours. I guess that is
    the kind of mirage Morison was talking about.
