That HAS to be a Crowninshield design. We have one locally (Newport) called "Fortune". About 52 feet.
Sorry to be so slow on the details. This is Martha, built 1907 in San Francisco. Designed by B.B. Crowninshield 68 on deck, 16 beam, and 8draft She is a bit of a celebrity in this area and can bring a smile to even non-sailors like myself. http://schoonermartha.org/index.html
Martha has a sister, for those that care. ;-) http://www.woodenboat.com/forum/showthread.php?t=103479
I'll see if I can find a pic of "Fortune". I remember her as lower to the ground than these two, but maybe she's just overweight....
