Here's a correction to my last posting. I had asked- "For his dead reckoning, did he refer anywhere to towing or streaming any sort of log, or did he, just like many old salts, simply guess his boat speed?" and- "But is Geoffrey also claiming that he used dead reckoning, rather than noon Sun altitudes, for his latitudes? That I would find hard to accept." Having now taken another look at Slocum's "Sailing alone around the World", I have discovered a sentence that answers two questions at once., written on July 27, 1895, a few days out of Horta, Azores (chapter 4). Slocum wrote " ...A meridian altitude and the distance on the patent log, which I always kept towing, told me that she had made a true course throughout the tweny-four hours." contact George Huxtable, at george@hux.me.uk or at +44 1865 820222 (from UK, 01865 820222) or at 1 Sandy Lane, Southmoor, Abingdon, Oxon OX13 5HX, UK. --~--~---------~--~----~------------~-------~--~----~ Navigation List archive: www.fer3.com/arc To post, email NavList@fer3.com To , email NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
