In a race last year we were sailing a close reach leg with 135% genoa and full main under rainy, gusty conditions, probably 18 - 20 with big gusts. We were hit with a gust clocked by another boat at 39 kt, in which we broached, rounding up and heeling to the point where a gallon or two of solid water came over the coamings, but I don't think the boom hit the water. We righted quickly, rolled up some of the genoa and continued on our way. I wouldn't call it quite a knockdown, but it was as close as I ever hope to come to one. The only way I can envision swamping is if a huge gust (50 - 70) knocked the sail into the water and continued driving the boat to leeward, forcing the sail under water. Hope never to test this!
