I have been out on my 192 in very gusty NW winds, and on a NW wind day at our lake, there's usually a big lift associated with the big gusts.
So one day I was sailing with full sail, close hauled W on the lake on starboard tack, and a big lifting gust comes. Normally I hang on to the tiller, and don't let her round up, anticipating a bit of "toe rail washing." This particular gust was big enough, lifted enough that I was WAY over-trimmed being close hauled, and long enough that I looked down from what appeared a very high height on the high side, to see water pouring in over the cockpit coaming. Luckily I finally started to head up, and the boat came upright with a wet seat. Of course, that's the side of the boat with the lazarette that opens clean through to the cabin, and I didn't have drop boards in.
Rather than tuck in a reef, I waited until the seat was dry enough to tack around, and headed back home figuring I'd had enough sailing for the day. Luckily that area was where the gusts are strongest on a NW day, so I didn't see any more gusts that big. If she had laid down much more for too much longer, water may have poured in the lazarette, which is not a good thing.
A couple years ago down on the Cheasapeake Bay in the Annapolis area, there was a Precision 18 that went out in late March, I think, on a very windy day. The boat sank, and one of the 3 people died of hypothermia. It probably got blown over on starboard tack, and the port side lazarette filled, and the people probably clung to the boat, keeping her on her side, and the cabin filled through that lazarette, and it sunk.
