there were a few 474's in Australia in the early 80's and there was one here in South Australia that had a jib. From memory it still had a fairly high bridle with an extension below the bridle/forestay connection which allowed them to have the jib tack lower than that point and still keep the bridle still quite highly mounted. It seemed to have a good turn of speed but I never saw any of them ever raced. They were relatively heavy when compared to the main cat that they would have had to compete against I.E the mosquito, but no problem when matched against the Hobie 16
