    IMHO, use the short dip formula/tables if you can see the shore.  If the
    shore is not within range, you are good to go--use the natural water
    horizon.  The 6225 ft elevation relative to the sun, stars, and planets will
    be lost in the noise.
    Will let the better educated answer on moon parallax, or refute my opinion.
    Happy new year
