Hunter 34 Lake Michigan
This spring I bought an '85 H34 and I sail on Lake Michigan. My learning is coming along and due to lack of real interest from the family, I mostly single-hand, although I never go out alone. I have also struggled from a lack of wind. Most days are 5 kts or less, like today. I did, however, install a downrigger and the kids love Salmon fishing (2 good ones today).

On our way back to the harbor a large T storm developed to the North of us. It seemed quite far away. After a short deliberation, I decided to drop the sails, as I thought this was the preferred course of action. There have been several capsizings this year during thunderstorms, most being experienced sailors.

A few short minutes later (first lesson, they aren't are far away as they look, at least not the bursts), the strong wind hit. I kept motoring into the wind, until it started to howl and blow the water into the air as mist. My first inclination from reading was to stop and get below until it passed (typical summer T-storm, not a system). I ultimately chickened out and chose to run off (notice speeds as high as 9 kts). The storm was to the North and the wind was blowing South. I rode the wind for about 45 minutes until it was not gale force and then wen't below. Was completely soaked and I was only on the edge of it. After riding it out for a bit, a new storm was developing south of me and the North was now clear, so motored back north to Harbor. Was amazed that 45 minutes of wind could develop 6 foot seas, as the lake was basically dead calm before the storm.

At the dock a guy on a neighboring mooring said he clocked 45 mph winds. I asked what he did and he said he just took down the sails and went below to ride it out (he has a 36' saiilboat). This is what I thought most sailboaters do on Lake Mihcigan.

My question is, did I do the right thing or should I have just went below? I had plenty of searoom and knew that breaking waves couldn't develop in an hour in 80' of water.

What scared me was an experience I had 2 months ago. I was on the boat doing maintenance work while on my mooring. I had watched a bad storm develop just off shore. Major lighting and eery, deep black clouds (tornado type). I was quite scared. While watching this develop, I saw very large chunks of water being blown off the sea. Shortly, I saw as very large wall of water lift about 25 feet above the lake. A few seconds later, the neighboring boats mast came over and missed my boat by a few feet. A split second later, my boat was on its side (about 80 degrees tipped). I was standing in the companion way, so well supported. I bounced back up and the rest of the storrn was classic fare with pretty intense wind. All the dinghys were flipped. The prevailing wind was 90 degrees from the burst (presumable off the cell a couple miles out). This presented my broadside to the burst. Mind you, I was in a harbor and waves were 3 feet at best. I was simply amazed that wind alone could knock my boat over.

Needless to say, this experience has intensified my respect for what a storm can bring. This was a "super cell." The rotating type that spawns tornado's and water spouts. A tornado actually struck a few miles south of my harbor, confirming my suspicion of the deep black. low clouds. The harbor 4 miles north, clocked gusts of 94 mph from that cell. As it moved down the lake, it capsized three boats off Chicago (headline news). I wondered how they were handling it when they went over. I suspect they had sails up, as it was dusk and the storm was not predicted.

I appreciate your support as I go through this learning experience. I try to learn all I can from events like this. We must always examine our decisions and pull out learnings.

I feel that I handled it well, but not sure it was best handled. It's amazing what you hear on the radio. Shortly before we were hit, there was some panicked guy on the radio asking the coast gaurd what to do. Made me glad I had done some research and knew my options and dangers (getting near shore or harbors).

Thanks,

Larry

Thunderstorms (as you can attest) can be very nasty and it is not terribly uncommon to see bursts of wind in the 60-80 knot range. Here in the South, we've even had measured 100knot bursts. That's hurricane strength. I've been fortunate to have only been caught out a couple of times so my experience is minimal but I do not understand the "go below" response. I'd rather be in a position to try and control the boat under motor than abandon that control and let the boat be blown in whichever direction the wind decides.

JMHO and $.02 worth.

On the Chesapeake Bay, mid summer thunderstorms can sneak up on you out of a gray haze and scare the crap out of you with the first boom of thunder, so much so that you think you've sailed into an ordanance test at Aberdeen or Pax River. You don't get a whole lot of warning sometimes as they can move so fast.

I've done different things in different circumstances. The Chesapeake Bay is mostly shallow, at less than 20 feet except in the shipping channels. One time have dropped anchor and waited one out. Intense winds and three to four foot waves inside of five minutes of the first outfall's blast.

Another time buttoned up, donned foul weather gear and powered through it when anchoring or running wasn't a choice. Yet another have run for the cover of a protected location off one of the Bay's tributaries and dropped anchor.

Having sailed off Chicago a number of times, your choices are more limited. And, it sounds like you gained a lot of experience from the choices you made. I'll bet the H34 felt solid the whole time!

I was out in the same storm as you. We were near the 4 mile crib when we saw it coming. We turned around and proceeded to sail back to the harbor (Jackson Harbor). Winds picked up and the rain came. I sent my passengers below so they did not get soaked. We were on a reach/run. We kept our 150 jib up and made great time (7 kts.). Once it was time to head West we were way over powered with the 150. We dropped the jib and reefed the main (also started the engine) and kept up at 6.5 to 7 kt's to the protection behind the break wall. At the point we dropped the main and headed into the harbor. Our whole get away probably lasted 45 min. Once we tied onto our mooring the weather settled down, the sun cam out and we ate lunch. That was also the first storm I sailed in. I think our only mistake was waiting too long to reduce sail ( I kept hoping we could stay in front of the storm and drop sails at the mouth of the harbor).

The most glaring lesson was how fast large waves can develop. While I don't regret the decision to run, being on the edge of the storm, I think it could have been more problematic had the waves gotten much more severe. Curious on thoughts here. At what point does running before the wind with bare poles become dangerous?

When the storm first hit us, I went directly into the wind. I felt the bow moving around a good bit from the wind force on the freeboard (wind shifting some) Had I gone directly into the wind or 45* away from it while motoring, would I have been ok? I guess I panicked a bit thinking about the knock down I had a couple of months ago.

I don't like to run down wind on a storm becasue of resulting high speeds and the danger of broaching. In addition if you run with the storm you will be longer in it and if you have a lee shore in the way you may get pinned down. I prefer to "hove to" or motor into it with just enough power to maintain position and stearage.

It sounds like I shouldn't have too much problem heading into wind of 40-50 mph while motoring and this seems like a good strategy. Do I need to head right into it or can I approach at a small angle without having the bow blown off.

Also, Should I be dropping my sails when the T-storm hits? I am always afraid that having any sails up if 40-50 mph winds hit will be a big problem. Am I best off dropping the sails and motoring as a habit and put reefed sails up if the wind is not in that range? If I were to double reef the main and furl 2/3 of the jib in advance of the storm, will be I able to handle most storms without issue? This would allow me either to proceed or heave to, as appropriate. I have always been afraid to have sails up as it approaches in case it is a strong storm. I was reading about the Mackinac capsize this year and it seemed that the procedure for an approaching T-storm was to drop sail. Unfortunately, in their case they capsized anyways.

Thanks for the help here. I prefer to be prepared and not learn everything from mistakes.

Have a few of these under my belt. Caught at anchor in 6' of water with boats all dragging anchor down on me, very scary in 60 knots of wind trying to fend off a 30' boat. Got caught with the sails (main and 150 genny) up, went WAY beyond 50 degrees heel. The inclinometer gave up at 50 but the vertical surfaces where being stood on. Everything not nailed down went into the cabin sole. She came right back up (keels are COOL!!) and we turned her into the wind. Still a lot of heel but we could control her pretty easy as we were making about 4 knots even though we where beyond close reaching. Seemed to work best when the sails were just filling and had stopped shaking. Wind speed was above 50 for a minute or two then dropped to the high 30s. Biggest trouble was the mess down below and some broken glass. I think that if this where a longer storm I would have been able to trim the sails and continue on, no doubt with significantly more dampness in my shorts.

It was kinda fun but I’m not looking forward to the next one either.

My 2 cents, I always try to get the sails down way in advance, if you think you may have waited too long, you probably have. Remember that sail that furls so nice and the main that drops down is not happenin in 50 mph wind. If I am positve and I mean sure I will go for the mooring. However if you don't make it, my anchorage for example has 170 pin ball targets to hit, I think I am better off in open water engine on. Survey the area and KNOW where safe water is in front of you and you can then motor into it just hard enough to do a knot or 2, you usually can't see 50 ft, so is important to know the scope of degrees you can head. If u can set an anchor I still like to keep the motor running in gear kind of helping the anchor. If u get caught sails up no motor heave to. I have exp several and I am glad they usually only last 45 min..... Red

I have cruised and lived aboard a hunter 34 for several years in Florida, Storms were a regular occurance. In other boats i have left up the main for good control and sailed it out. With that boat the main can still leave the boat in a dangerous place. I preferred a reduced foresail only and the motor on idling just in case. I have seen Two hunter 34's in florida that did not reef on time and they lost masts. Hunters 34s are still the most fun to sail (aside from beach cats) in my opinion, but you must reduce that sail area about 10 minutes before you think you should, storm or no storm. I dont like going below for any storms, some of them bave a cyclical effect and the wind change, so you want to be prepard to chang sail and course respectively. I think sailing with reduced sail is actually the most comfortable way to get through a storm.

Agree with Teacher...

dropping the main on my H34 is the first course of action when a thunderstorm is bearing down. With it's tall blade it leaves a lot of sail area exposed even on the first or second reef with a shoal keel. Much easier to control the headsail or roll it up than to drop the main in a blow.
