EarthBM 89 Posted November 11, 2020 Share Posted November 11, 2020 Odd... Hallucine, which won the last ARC, had as competent crew as any cruising cat could. 16-20 TWS, two reefs. They claim the capsize happened after hitting something in the water, but the hulls seem intact (pic). It did happen around where killer whales have been attacking boats’ recently. hmm... thoughts? https://voilesetvoiliers.ouest-france.fr/securite-en-mer/disparition-en-mer/le-catamaran-hallucine-de-regis-guillemot-chavire-au-large-de-vigo-un-mort-trois-rescapes-491bc45c-237e-11eb-97e1-64af5fb563fa https://www.is.fi/kotimaa/art-2000007609445.html Quote Link to post Share on other sites

Because they just slip through the water easier and they generate larger rig loadings with the wider beam, they usually reduce the rig size to produce a really stable safe platform. Even then, sailing/racing at night on multi-hulls is a very different experience in risk management. The penalty for not seeing and getting hit with a squall with the rags up on a mono is a knock-down, on a mutlihull it can be a capsize. Not sure about the bigger boats being more difficult to put in the piss, you are probably right but it just depends on the circumstances. 1 Quote Link to post Share on other sites

I’d think beam is more important than length, it’s hard to imagine going ass over teakettle. It’s easy to imagine going over sideways. TS5 is 8,6 meters wide, GB68 is 9,12 and HH66 8,7. So yeah, it is wide! Quote Link to post Share on other sites
boardhead 290 Posted November 16, 2020 Share Posted November 16, 2020 So you hit something that causes rapid deceleration or change of heading and/or damage to hull(s) or appendages which leads to deceleration pitchpole or increased TWS due to that deceleration or different angular exposure due to directional change from the impact or lack of control from appendage damage etc,etc, etc. Not enough information on the incident to make any determination so it's all conjecture. Two reefs but how much foreword of the mast? The capsized shot shows some swell but how much and how long after the incident was that picture taken. Lack of underwater damage save the missing board and high freeboard indicating no hull punctures suggests she sailed over and 16 - 20 with a big reacher and a broach on a light boat might be enough. Conjecture on beam ratio/rig height without displacement or prismatic is grasping at straws too. That's a fine boat representing the current development of fast, fun, offshore cats so let's hope there are some lessons learned when more specific information emerges.

I have had a similar incident but not at night and no fatalities ... Beam ratio absolutely plays a part .... my boat is a racing boat and is close to 1.5 with low volume in the bow and large roach in the main so not surprised that when it went over it was more pitch pole than capsize ..(A bit of both really). The TS5 is a safe ratio and a well proven fast ocean cruiser that can be raced so a safe boat in my opinion. it would be great to get the actual reasons for this capsize for all to learn and hopefully help avoid future incidences but unfortunately we rarely get the actual blow by blow, warts and all account due to either an ongoing investigation from police and or insurance (In my case) Sometimes those that were there just don't want to talk for whatever reasons as that's their right. Sailing the worlds oceans is never totally safe regardless of the boat and in life accidents happen so the secret is how to limit it to an acceptable percentage.... for me it's risk Vs mental reward in racing... but i learned recently in my crash that I risked others for my reward which is not acceptable and I regret that and have learned from it. I believe a bigger problem now that impacts us is No.1... the shear quantity of inexperience people now out cruising the world. It seems with youtube the new phenomenon is to buy a boat with a GPS and go with next to no real time sailing / traveling miles under your belt and No.2.... The amount of large floating objects in the ocean ready to take you out at any time. This boat is now part of that problem and should be removed. I hope the boat will be recovered and if so we will hear more .... Condolences to the family 2 Quote Link to post Share on other sites

One of the two boats was Hallucine... Interesting how Charles prefers to reduce the foresail first, because it can make it harder to head up in a gust; and also it will power up more than main when bearing off. This is kind of opposite to my intuition that it's always easy to depower the foresail by just dumping the sheet, while the main can be a problem in a bear-away situation. I suppose that if you're single-handed, your just have the main and traveller sheets in your hand, and leave the foresail as is in a gust? He also says to not bear off with the hull flying - again, it felt to me that you want the centrifugal force helping you by bearing off. No advice on what to do when the lee bow is stuffed.

Then we'd keep depowering by putting in a reef of the main. And we added cam cleats nearby the primary genoa winches so we could blow them faster in a hurry. This was after another Atlantic 57 capsize. The mainsheet was in a double cam cleat (4:1/8:1 mainsheet) so if you flicked both it would run out very fast. Traveller was on cam cleats too.

It wasn't super clear but the reducing the jib first is in the context of going upwind, he's saying that on MOD70s if you are trying to luff to depower with 2 reefs in the main and big jib it will actually round down if you dump the traveler. Going downwind would definitely be the opposite where you want to reef the main first. Quote Link to post Share on other sites
SeaGul 97 Posted February 27 Share Posted February 27 Bear off or luff up; its easier to control a luff - bec all sails are depowered without doing anything but turn the rudder. In a bear off with flying hull - on the edge - if sails are not eased perfectly it can easy tip over. The heeling moment will not be so big in a luff bec that is usually not many degrees - in a bear off it can help - but the windforce will easy counter it. Quote Link to post Share on other sites
Laurent 1,918 Posted February 27 Share Posted February 27 6 hours ago, soma said: There’s a transition where depowering is turning up or turning down. That transition is at about 90 degrees. We’ll call out “out is down” or “out is up” just so all crew are on the same page. If “out is up” you generally hold the sheets. If “out is down” you have to let the driver down. If conditions are marginal we’ll sit solidly on one side or another of that transition (75-80 TWA or 105-110 TWA). When things are really bad on my F40 there almost isn’t an “out is down” because the bows are getting pushed down too much and you’re on the verge of a pitchpole. In the video, Charles Caudrelier is talking about "l'angle mort", the dead angle; between 95° and 105° TWA. More upwind, you head up to let go some power in a puff. More downwind, you bear away to let go some power in a puff. But in that range, there is no hard rule, and depending on the sea, the reaction of the boat, it is up to the helmsman to figure out what is best (or not worst...). He explains that on the new foilers like Gitana 17, it is not really a problem: more wind = more speed = more righting moment from the foil... But on the other hand, with the ORMA 60 trimarans, there were some conditions where NOBODY would sail at those angles. Just too dangerous... As noted by others, interesting to see that he would reduce head sail first. That is not what they were doing there with the organized daysail with the shipyard people, and he was politely saying that it is not what he would do. He said that on fast trimaran, they go all the way to J3 with full main before taking a reef. On top of what EartBM explain above on the reasons to do so; Charles added that to reduce your headsail, you need to bear away to furl it anyway. (He said that if you go upwind and let your jib flock to furl it, you are going to ruin it...) If the headsail is not the first reduction of sail area you do, it means that when you want to reduce headsail, you are now maybe in a squall, and you will have to go through that 95 to 105 dead angle range to do so, with too much headsail, not safe... 1 Quote Link to post Share on other sites
tr1plet 15 Posted February 27 Share Posted February 27 There is also another reason to first reduce the foresails on ocean-going high-performance multihulls: For structural reasons, you need the main sail supporting the mast where the corresponding forstay of the foresail you are using is in the lock. Thus, on our Lorima carbon mast, you cannot use the mast head lock (for the spinnaker) or the one between the J1/Solent and masthead (e.g. for the screecher) with a reef in the mainsail, or the J1/Solent with two reefs in the main. 1 Quote Link to post Share on other sites
bushsailor 111 Posted March 2 Share Posted March 2 Really valuable video, everyone should watch it. We capsized a multi doing the exact opposite as explained in the video ie eased the main, heady took control of the boat 40kn gust could not head up quick enough ..... slow sideways capsize. The whole capsize was caused by not easing the heady. Any depowering now is done with Heady first. Before we actually did it I would have never thought the heady would have been able to capsize the boat. The other point made was not to bear away when reaching when flying a hull. Reason for that is that hull is already under pressure supporting the whole boat and it does not have as much reserve buoyancy so there is a danger of it nosediving. 1 Quote Link to post Share on other sites
teamvmg 119 Posted March 2 Share Posted March 2 They translate CC as saying the 'DEAD ZONE' which implies that there is not much going on there. A better translation is the 'ZONE OF DEATH' which implies that there is a lot going on there! I think he then says not to sail in the zone of death if you are powered up. Sail below it - then you can bear away if needed, or sail above it - so that you can luff up if needed. 2 Quote Link to post Share on other sites

I know you meant head sail but never heard it called a "heady". When the windward hull is flying it has zero reserve buoyancy (righting moment) and isn't likely to nosedive. If anything, the leeward hull might nosedive but that's more likely when the windward hull is is still in the water with reserve righting moment. Many factors like angle of aerodynamic force on the sails, boat speed, wave height and timing affect nosediving of the leeward hull but in general, I would say that if the windward hull flies before pitchpoling, the boat will likely roll over sideways without burying the leeward bow. Pacific proa theory. Quote Link to post Share on other sites
hump101 469 Posted March 2 Share Posted March 2 Not bearing away with the windward hull already flying is mostly because if the hull is flying the point of maximum stability is already exceeded. As the boat bears away the wind comes aft, increasing heeling moment, whilst the righting moment is reducing - an unstable combination. With the windward hull in the water the righting moment is increasing as the heeling moment is increasing - a much more stable relationship. This holds true for lateral and longitudinal stability.

I think upthread, one or two posters might be using pitchpole as general term for a catamaran capsize My first boat was a Hobie 16 - and this could pitchpole easily modern cats have hulls designed to go through waves - so called "wave piercing" hulls, and I think are pretty unlikely to actually pitchpole. The biggest danger is having the leeward blade too far down, although it seems that in this case (the TS5) it wasn't down, and I think everyone who sails these boats realizes that they can capsize even without the leeward board down My experience is that on these really powerful cruising cats, you need to be thinking way ahead - once it starts getting scary, it can be too late to do anything to the sail plan and you can be stuck for a _long_ time going way faster than you want to go - basically just hanging on and hoping for the best..

Yep and a great example of this is ....Sodebo @ProaSailor I believe Bush is referring to the leeward hull.... He would know as pushes his over 40ft (kind of) cruiser racer very hard indeed and would have found the limits more than most... Heady is a very Australian term... We shorten just about every word possible.... Quote Link to post Share on other sites

Sail below it - then you can bear away if needed, or sail above it - so that you can luff up if needed. We used to do something similar when sailing on an I14 and even on my F16 . If it was a reach with a bit on we would do a V instead of straight lining it . We would go high first for halve of it then go low for the second halve . Worked on my single handed F16 as well . You were able to do most of the work with steering input rather than massive amounts of sheeting while on the edge . Quote Link to post Share on other sites

It actually started life as a sub 40’ Adrian Rogers design which he extended to 50’. Has anyone got a link of the capsize of Afterburner in the 1997 Coastal Classic. A very interesting flip. 1 Quote Link to post Share on other sites

This is exactly how we think about sailing our A57, and we always reduce headsail first. Full main and staysail is a very capable sail combo. Put a single reef in the main from there and it's rare to need less sail....We've had two reefs in three times I can think of in 8,500 miles between Newfoundland and Grenada, and never for long. And we only once had two reefs and a single reef in the staysail, beating into winds gusting 31.5 True with 10' waves - boat did pretty well - though a very narrow sweet spot in those conditions. 4 Quote Link to post Share on other sites
Bill Gibbs 28 Posted March 20 Share Posted March 20 No disagreement with most of the comments here. Dumping sheets is always a solution, even in the zone of death. I've researched a lot of capsizes, and being unable/unprepared to do so is a common thread. Afterburner's capsize was with the previous owner. In my 15 years with her, my scary events had similar causes, sudden stops followed by rudder overpowered roundups leading to lateral capsize risk. We had winches with unused self-tailers, no cleats. We handheld sheets all the time on the winch, which wasn't a hardship for racing. At the tiller I held the main sheet in my forward hand, just like a beachcat. Event #1 had us doing mid 20's downwind off Pt Dume, Calif. With a couple crew new for the day. A big kelp island appeared in front of us and we attempted a very fast gybe, unsuccessfully, as the main sheet was overwrapped on it's winch (newbies). We hit the kelp and stopped, a bit nose down. The apparent wind clocked aft and built to the true wind. The main hooked up, created huge weather helm and Afterburner started rounding up at slow speed, overpowering the rudders, and heeling over. I was barely able to hold the helm up, slowing the roundup, until they dumped the main from the lee winch. Seemed like hours. A lateral capsize after a sudden stop and roundup is a real danger. Event #2 was double reefed in big winds and big steep 16' (?) seas, downwind again. Couldn't slow down below wave speed and surfing was crazy fast. A bigger wave stuffed us right into the back of the one in front, water up to the mast, rudders out of the water, and a big slow down. 20% of a pitchpole? Spin was released as this happened, and the main shortly after we slowed and started to round up again, the sterns came down. Our newbie that day was a mono racer who thought he was going to die. It was a bit hairy. We had Wahoo in the same race years later, same location, similar winds and seas, and the same thing happened. Because Wahoo isn't as overpowered as Afterburner, we hadn't reefed yet (a mistake). Big wave, we surfed down it and stuffed big time, water over the cabin top. On Wahoo I helm at a wheel standing. I was knocked down, couldn't see a thing. But I could feel the stern rising. The spinnaker block lashing had failed at impact, taking out a lifeline stanchion, and jamming block & stanchion on to the winch preventing further easing. The failure had eased 8 feet or so of spin sheet. This was pretty lucky I think. I could feel Wahoo starting to round up and heel as I'm screaming for someone to dump the main. He'd been knocked down too. He got it dumped. We got things sorted out and got back into the race. Deja Vu moment. In bringing Wahoo home 4k nm, we reefed early, often at night, ran a screecher instead of spinnaker, hit squalls, big seas and big winds, and never approached a capsize. Over 14 knots of boat speed we'd have someone standing/sitting by a sheet tail, in a cam cleat off the winches. In an early leg, the autopilot had us surfing down waves at 19 knots while we had dinner and toasted her tracking on rails. It dawned on me that this might not be a safe cruising practice, so we got in the habit of reducing sail whenever there weren't crew standing by to respond. 6 Quote Link to post Share on other sites
