This was a real missed opportunity shot.  A few moments before the rainbow was on the other side of the boat and it looked like the boat was sailing in to it.  

unfortunately i was driving, so i stopped the car and grabbed my compact camera which isn't as easy to control and burnt out the highlights of the white boat. I also note i cropped off the second rainbow just to the right of the frame. 

oh well.  say lavey.  go on.  say it.   thank you.
