    Greg - 

    I haven't had time to work it out, but, gad!!  that's an amazing photo.    So, the conditions are what over the water?   I have been reading in the news about the freak Santa Anna winds, and as I recall they're quite hot, so you have very hot air over cold water, which will create some interesting conditions.  

    Is there a rough air temp and a rough water temp you know of?

    Today's linked image was taken from a jetty at Channel Islands Harbor from a height of eye of 19 feet. The distance to the left end of the breakwall is exactly .37828 nautical miles. Minutes of arc per pixel is .0975'.

    What is the difference between measured dip from horizon to breakwall left end and the standard for the given distance ? (Santa Ana wind effect)

    Extra credit-How far is the closest sailboat ?
    Double bonus-How tall is the sailboat's mast?

    note-for those without iPhoto or photo shop the pixel measurement from the horizon down to the breakwall left end is 238 pixels.
