    The book "Latitude Hooks and Azimuth Rings" has a basic version with how-to. I 
    constructed the weatherglass and it worked well. From Amazon.com

    As anyone who has read Patrick O'Brien's Aubrey/Maturin novels knows, the
    use of a log line is often mentioned. It is essentially a board with a
    bridle and a long knotted line on a reel. I surmise that the bridle was used
    to keep the face of the board perpindicular to the water flow in order to
    maximize the drag on the log. It was the midshipman of the watch to use the
    log to ascertain the speed of the vessel at periodic intervals. I am sure I
    am not telling members of this list anything they do not know! I would like
    to duplicate this speed log for my own sailboat. I understand that the log
    was tossed overboard and a 30 second sandglass was turned. The board pulled
    the knotted line off the reel and the mid counted the knots that passed thru
    his fingers during the 30 second interval. He then nipped the line which
    caused the board to become more streamlined (parallel to the flow)  in the
    water and the line was reeled in. The number of knots counted equalled the
    speed.
    
    Is there a description somewhere that would tell me how to duplicate such a
    log?
    
    Any enlightenment will be appreciated.
    
    TIA
    
    Vic
