Hi Fred, you wrote: "Slocum DOCUMENTED but one lunar that he shot during his circumnavigation. We don't know how many he shot, although available evidence, his book, suggests he shot only that one." There's more evidence than that in the form of a letter written in the shade of a plam tree on a beach in the Keeling-Cocos islands (in the Indian Ocean, south of Sumatra) and mailed home to New York in August of 1897. Slocum was more than two-thirds of the way through his solo circum-navigation, and he wrote how impressed he was by the accuracy of his landfalls despite the fact that he carried no chronometer and despite the fact that he had taken only one lunar observation on the whole voyage up to that point. The letter was collected by Walter Teller and included in his detailed biography "Joshua Slocum" published in 1971. Teller took no interest in Slocum's navigational methods and quoted this letter mostly because Slocum continues on in it musing about starting a sea-going navigation "college ship" for young women when he returns to America. It sounds like he wants a great sailing ship filled with beautiful women, sailing the seven seas, where he is the sole instructor in celestial navigation. Now there's a plan hatched on a tropical beach! It's possible that Slocum became a born-again lunarian the very next day after he wrote his letter, and maybe he shot many lunars after that, but the descriptions of his navigational methods in "Sailing Alone Around the World" after that date are strictly traditional DR, so if was "born again", he certainly kept it a secret. We could also entertain a "statistical model" and hypothesize that his rate of taking lunars was equal to the rate in the earlier portion of the voyage in which case there would be a 50% chance that he shot another in the remainder of the voyage after that letter was sent. -FER PS: "Joshua Slocum" by Walter Teller, Rutgers University Press, 1971. The text of the letter is on pages 147 to 149, and a photo of the first page of the letter is on page 85. --~--~---------~--~----~------------~-------~--~----~ NavList message boards: www.fer3.com/arc Or post by email to: NavList@fer3.com To , email NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
