After having a couple of days to reflect on this incident, I've decided to share the experience and lessons learned.My wife and I we're returning home, to the Boston area, from the Mystic rendezvous last Friday on our H410. We had left Woods Hole MA at 7:00 AM for an approximate 8-9 hour trip home. Visibility was about 1-1 ½ miles with heavy haze. I had the radar on the entire day because of the haze. Sea state was 1-2 foot waves and a SW wind at 15-20 knots. The weather forecast was for possible severe thunderstorms after 6:00 PM. We caught the current thru the Cape Cod Canal, and once on the east side of the canal had a broad reach up Massachusetts Bay. We were running between 8.5 and 9.5 knots. By the time we reached Plymouth MA we were fully an hour ahead of what was our projected schedule. We were projecting to be home by 2:30 pm. Everything was going tremendously well. At approximately 12:30 the winds picked up to 35-40 knots and we put the second reef in the mainsail and reefed in the jib. Also started the iron genny so we could maintain speed. Some where around 1:00PM the winds had dropped back to 15 knots and I considered raising the main again. At around 1:15 PM the Coast Guard announce the National Weather service had issued a severe thunderstorm alert. The report was kind of nebulous. It indicated a line of severe T-storms from Harrisburg PA to 35 miles east of Portsmouth NH. I knew my general geography well enough to know we were going to run into the storm. At this point we were around 12-14 NM from home with no optional port a refuge readily available. We did our storm prep with foul weather gear, closing up and the like. At around 1:30 PM I felt a very cold gust of wind and ordered my wife below. The radar showed no indications of rain and the sky above was still blue and obscured sun. Within five minutes the winds had shifted to the NW (about 25 degrees off the port bow) and increased from 14 knots to over 50 knots and still increasing, it was raining and serious thunder all around us and I still couldn't see any lightning. At this point the boat was still heeled at less than 20 degrees when it really started to blow. Hanging on for dear life, and trying to keep an eye on things when I could see, the wind continued to increase. We caught a gust and the boat had a near knockdown. The starboard rubrail was 1 ½ feet under water. The first lifeline was under water and my fenders were threatening to float out of their holders. The portholes on the starboard side of the saloon were under water! I couldn't see the inclinometer, but can anyone out figure the degree of heel at this moment? The boat did what it was supposed to do and developed weather helm, righted and pointed back to the wind, when a second gust did the same thing. The lower spreader was within feet of the water and the rubrail was again under water. I had managed to see the anemometer twice during this time and it indicated 65 knots and 70 knots respectively (remember this is average wind speed). I should mention the boat was on AP the entire time, and the seastate remained at 1-2 feet. Within no more than 15 minutes from the first gust of cold air, the winds started decreasing. Never in my sailing and boating days have I been so happy to see winds at 45-50 knots. (The boat handled very well with the winds back under 50 knots). I know this story takes longer to read than the time that actually elapsed, but we went from 14 knot winds to 70 and back to 20 knots in under 20 minutes. The boat sustained virtually no damage and her crew survived with no harm. I don't ever need to go through an event like this again. An interesting aside, I'd been towing my dingy on a ½ inch three strand bridle attached to both stern cleats and attached to the dink with a 1500 lb WL shackle. The bridle had separated and the bend in the SS shackle had been totally straightened. Needless to say if anyone on Mass Bay finds a gray inflatable with T/T Spellbinder lettered on it please contact me or the Boston Coast Guard.As hindsight is always 20-20 here are the mistakes we made and and are willing to share. 1.I underestimated the weather window. First time and last time. This is probably the single largest reason for cruising boats getting into trouble.2.I had no formalized "5 minute emergency plan". If I had had unfamiliar guests aboard it could have been disastrous.3.We lost precious time grabbing foil weather gear, harness and the like. It was all stored in the saloon. At least the harnesses and tethers should have been topside.4.My cockpit has only 2 tether attachment points behind the wheel. I couldn't have gotten forward in the cockpit to the running rigging even if I had tried.5.Even with the second reef set in the main and a small jib, we had way too much sail for the winds we experienced. Even if we had had a third reef, I probably couldn't have set it, under those conditions, even if the above weren't true. It's been said on the forum many times, reef early, reef a lot.6.Always anticipate at least 2 times the worst probable conditions. I didn't even come close to anticipating the conditions we experienced. 7.Take the time, in advance, to make sure any and all guests are indoctrinated to the entire boat. S--- happens very quickly sometimes. I have other items that have moved up significantly in my priority list. These include an EPIRB and a life raft. As always with a boat, when money allows.I know this was a freak of a storm, and I hope to never encounter conditions like this again, but if I do I'll be better prepared. Hope this helps others out there, because it could happen to you.BryceS/V SpellbinderH410PS. I kissed the boat after we we're on our mooring. This experience answers any doubts I may have ever had about the seaworthiness of my H410.
