    Re: Artificial Horizons

    I have the small plastic artificial horizon that Davis used to produce, and used it with motor oil. Though the oil had to be kept in a different jug, I didn't need much and the size of the Davis made it easy to transport. I've only used it a few times; once taking a series of shots along a cove I was trying to chart.
    My only other experience with artificial horizons was in a dead calm fog bank off Nova Scotia. The sun broke through, but the horizon was nowhere to be seen. I quickly "borrowed" a baking pan from the galley and some motor oil from the engine room to get our only sun line in three days . It worked quite well, though neither the cook or the engineer seemed very impressed, as I recall!
    (By the way, this was on a sail training voyage in which we had started the week attempting to stick to celestial for education purposes. It should be noted that despite the visibility, our DR, GPS and radar helped maintain safety margins.)
