I ran aground in my '88 35 on sand with a lee shore in 2-3' waves off the lighthouse on Key Biscayne Florida. Missed the outer marker of the channel, really stupid. Every wave would pick the boat up and bam! throw it back on the sand. We tried to motor out, every wave would pick us up about enough to go one foot then bam! it'd slam back down on the hard sand. It was terrible. The whole boat would shudder and it sounded like it was taking a terrible beating. This went on for what seemed like an hour, thoughit was probably less, before we finally got back into deeper water. I was sure that we had messed up the rudder and the keel. But when I took a look at it later, however, they were fine. I probably damaged the fiberglass a little bit on the top of the trailing edge of the rudder, (I didn't notice it until it was hauled out the following month, and there might have been a couple little dents in the keel that weren't there before, not sure, but the biggest change was all the barnacles got scraped off the bottom of the keel. It was quite a pounding. The winged keel and rudder are tougher than you think.
