     < If you are on a watercraft half way between,>
     You're not disagreeing with me, you may have just failed to note that I
    pointed out the fetch is 4000 miles--to the Califormia coastal sailor. The
    fetch will be different at every different distance in the path.
     Without looking it up, I only recall "seiche" motions from oceanography
    class. When you are walking with a cup of tea and the tea finds a motion
    resonant with the dimensions of the cup, the motion reinforces itself and
    the the tea slops over the side of the cup. This resonant motion reinforcing
    a wave is what I was told is seiche motion. Not just the wind building up
    more water at one end of the lake, that's not seiche motion. If the buildup
    causes the water to slop back and forth across the lake and a resonance
    builds up which increases the wave height on the shore--that's what I was
    told is seiche motion. I won't swear to that, I never asked the professor to
    cite his sources. Could be you're hearing a misuse similar to "rip tide"
    and fisherman asking what time slack tide is, when they mean slack current.
