    Re: Endeavor Voyage Recreation

    I find the comment about using lunars interesting.
    On one of Cooks voyages he took a copy of Harrison's chronometer with him
    (was this the same voyage as they are reenacting on the BBC ?).
    In the book "From Satellites to Sails" by J.E.D. Williams, Oxford
    University Press 1994. Page 102 with note reference to  page 106, referring
    to Harrison's chronometer no. 4
    "...There was not the remotest possibility that a copy of No. 4 could be
    put aboard every ship. The Board had to pay the enormous sum of 450 pounds
    to Larcum Kendall to make an exact copy (ref. 21) of No. 4."
    Ref. 21: This was the instrument that gave Captain James Cook such
    excellent results. On the conclusion of his second voyage of exploration,
    Cook wrote in the log that on making land about Plymouth on 29 July 1775,
    the error in longitude by Kendal's watch was only 7' 45". how Cook sights
    with such accuracy he does not say; but there is the entry in his own hand.
    While commanding Endeavour five years earlier Cook had remarked 'an
    observation (of longitude) to within 30' of accuracy sufficient for all
    nautical purposes'.
    I note the slight difference in the spelling of Kendall in the text and the
    reference - only 1 "L" in the reference.
    My copy of "The True Story of a Lone Genius Who Solved the Greatest
    Scientific Problem of His Time -- Dava Sobel;"  is in London (I'm in
    Venezuela), I am sure that some of our readers have this book; it would be
    interesting to cross check and see if  there is any reference to Captain
    Cook in this book.
