It's probably closer to 80-90 degrees for most of us. Tacking angle isn't everything though and is hard to compare to monohull world. Speed is king on cats and although we can sail just as high (or higher) than any other monohull while still going faster, we can get to the top of the course more quickly sitting in the 80 to 90 degree range. Speed through the water increases dramatically as we crack off of the wind.

Talk of tacking angle also ignores the effect of speed - apparent wind angle. Because we move faster, our apparent wind angles are much higher and our sails/mast/tuning are tailored to handle this high apparent wind angle. This is ultimately the limit of getting to the top of the course in short order.
