I thought that SF Bay sailors would appreciate this shot. I found it in a September 1970 issue of "The Skipper" magazine.
The caption (which I couldn't scan with the photo) reads: "On an April Sunday afternoon west of the Golden Gate Bridge, in gusty winds of fifteen to twenty-five knots and six foot swells, photographer Michael Murphy caught the twenty-two ton ketch Cayuga leaping off the top of a swell and into the trough. It was the only picture he got, for conditions were too dangerous to shoot any more."
I am attaching the photo. I hope it comes through. When you see it, you'll know why the photographer decided to retire from the field!
