    Wow 17 Lunars at sea in a wide range of conditions. Fantastic!! Could i ask the question "As a seaman what ship would a crew member have more confidence in  being aboard,a ship where the crew are aware of the conditions around said ship because they are regularly outside of the vessels bridge doing Cel Nav or a ship whose crew are all warm & cosy on the bridge looking at the GPS while a huge storm cloud approaches from astern.??
    My money is on the dude with a Sextant in his hand!!

    For the record, I've shot 17 lunars in the last month AT SEA on a ship of various bodies and in various conditions (including rolling 20 degrees) with a cumulative average error of +0.26 minutes of arc.  Each of those lunars aveaged 4-7 sights each.
    With modern reduction techniques (read computers) it takes a matter of minutes to reduce the sights.  I am certainly more confident of both my determined index error and my chronometer because of my lunar work.
