    Funny thing.

    Once upon a time we were underway in the NC sounds on AP when a guest came
    on deck with her water bottle. Shortly after she sat in the navigators
    chair I noticed the shadows in the wheelhouse begin a slow march across the
    room. When I glanced astern I saw our wake was a big arc.

    Our friend's water bottle had a magnet (purported to enhance the health
    qualities of the water) in it and the AP compass was about two feet away on
    the other side of the bulkhead.
