    Suggest read "Maskelyne, Ed Revecca Higgett.2014 and his own "British Mariners 
    guide 1763, in particular his voyage back from St Helena. 
    Using lunars, (probably the first to do that)he was pretty well the only 
    person on board who knew where he was, especially longitude.
    Seems like a pretty good navigator to me.
    Others  on board may have been great "navigators" in the traditional sense, 
    but had no idea where they were.(especially longitude).
    I'm a great fan of Maskelyne who has been much maligned.

    Was he?  What about his trip to St Helena in 1761 to observe the transit of 
    Venus, and incidentally to try out his ideas on lunars;  his trip to Barbados 
    in 1763 to observe Jupiter’s satellites and test Harrison’s watch, Mayers 
    Tables, and Irwin’s chair; and his trip to Schiehallion in Perthshire to 
    measure the density of the Earth.  As Astronomer Royal he would have spent a 
    lot of time gazing skywards from the house on the hill at Greenwich, and as a 
    cleric his soul might have been aiming even higher.  DaveP
