    I have tried bubble horizons at sea on numerous occasions. Even in a
    moderate sea, the bubble scoots around like a ferret on speed. An averager
    won't help in this case because it will just average out a series of
    demented observations. The averager was designed for the relatively smooth
    platform of large aircraft. It was never intended for use at sea.
    Trust me, I have tried many times. Even on a calm sea, using a bubble
    horizon can be tricky.
