Never did hear of one going over, but I did stuff mine in to a 4ft. swell. Runnig in from Brenton's reef I was doing around 16 knots with a following sea. I had been on course for about 4 miles when all of a sudden the bow stuffed into a swell, almost tore the wheel from my hands. The water came over the foredeck up and over the windshield and into the cockpit. She came right out of it . Soaking wet I slowed her down for the rest of the way in. Capt K
