    Re: Time recording,Russian manuals, etc.

    Allow me three comments, please:
    
    As for marking the time of observation in our days - for the lonely navigator 
    without the crew, it should be difficullt to mark twilight observations of 
    several stars on deck even with modern stopwatches you have mentioned - 
    either he has to write notes in the flying spray or to go under deck to make 
    them. Both is cumbersome. Is it not possible to use some sprayproof sound 
    recorder (a digital one today, not mechanical)? And I saw some "chronographs" 
    with the lap function that can be fitted to the sextant, e.g. "Datascope" by 
    Celestair, but other cheaper solutions in catalogues of sextant makers, too. 
    The combination of those two gadgets seems an ideal set for a today's lonely 
    celestial navigator (or for a holiday navigator whose family isn't interested 
    in CelNav :) to me.
    
    According to the standard Russian work on the nautical astronomy from the 
    fifties and sixties (Matusevich, "Fundamentals of the Nautical Astronomy"), 
    in no way was permitted to take the chronometer to the deck. For marking 
    observation times, the observation clock was used, jumping in half seconds 
    (or in 0.4 seconds, so as to make very accurate comparisons of chronometers 
    possible - by sound coincidences). This aggrees to Alexandre's quotation by 
    memory.
    
    I cannot understand, why the observing mate would have said "yest = yes sir" 
    to the petty officer marking the time of observation. This "yest" means 
    "There IS the contact now" probably, isn' it? Of course, I am not a Russian 
    native speaker.
