The build up to the America's Cup race in San Francisco in 2013 has already started with their one design, the AC-45. That is, the teams race essentially the same boat, designed by our friends at Morrelli Melvin Design.
The actual race is with the AC-72, which is much bigger, but they have been learning to sail these winged cats using the smaller '45s. They are using a rigid wing for the main sail, but still have a cloth genoa for their foresail, which makes an interesting hybrid. Also, unlike my thesis design, the wing is most definitely not self-trimming.
Today, on a practice run in San Francisco bay, one of them capsized. Actually, it pitch-poled, which is to say it buried the leading hull and went over the long way, not to the side. One of the things to notice is that as the boat is pitching over, the airflow from the rotation caused the wing to align to the relative wind and hit the water leading edge first. I am quite surprised that the wing did not break in the water, but one of the crew members did fall through the wing during the capsize (he suffered only minor injuries).
The article is quite light on the details, but the video is key.
