We recently weight one of the Bay Area 125 at 9385 in orr trim. So 9500 seems about right.We had our boat weighed yesterday for Pacific Cup. Brochure weight/class minimum is 9,300 lbs. We came in at 9,573. I'm quite happy with that, as it included 100 lbs of batteries, diesel heater, autopilot, dodger, solar panels, and charge controller, e-rudder bracket, two tacklines, and our new rudder is slightly heavier than the original. I suspect we had something like 200 lbs of extra stuff that a boat racing Worlds, for instance, wouldn't have. Pretty good for a production boat, I'd say.
FWIW, a competitive J/125 was weighed at the same time. Brochure weight is 8,350. Measured weight - 9,500. Boom.
