    Thanks for all the reactions.

    I don't quite agree with you, Dan; I think logs were carried by many if not
    all small yachts crossing the Channel or North Sea in a not too distant
    past. Trevor thinks so too.
    
    I regard it as good practice to keep a DR plot and a log is very helpful
    for that. I have tried to estimate speed from looking at the wake.
    Apparently I am a very bad estimator and I doubt if I will ever be able to
    make a satisfactory guess under quite different circumstances of wind, sea,
    day or night, etc. Even if I could: would my crew be equally proficient in
    the time that he is on watch and me asleep?
    
    Doug Royer's suggestion of showing shapes and lights indicating that I have
    something in tow was also ventilated by Jared Sherman. Indeed, as a
    variation on Dan's objection to that, the signals will not be recognised
    (or even seen) by helmsmen that don't spot the log line hanging from my
    stern. (What is DAMHIK, Dan?) An other objection could be that, if I
    remember the COLREGS well, signals are prescribed when towing vessels. A
    log rotator does not count as a vessel.
    
    If George feels uneasy about his log line troubles, he might like to know
    that I once entered a lock, doors closing while I manoeuvred alongside,
    totally unaware that the log line was still 'in use'! All sorts of nasty
    things could have happened to it: caught in the propellor, or between the
    doors, but we were extremely lucky that time...
    
    Jared's suggestion I hold for extremely valuable: to have a few cast before
    your last one is gone. Once you have a good mold, the price will almost
    surely be less than the cost of a new/second hand complete set. Thanks very
    much, Jared.
