I typed this up as a reply for someone but i think its a good enough breakdown to post it as a stand alone. (the question was, what caused the hole in the hull?) --------------My answer ------------- Non release of the backstay prevented dumping the top of the main. they powered up like a windsurfer or a foiling moth, as the boat loaded up you could see it pivot to port and rise . This is made worse as the rudder gets more and more exposed, reducing turning efficiency. This is highlighted at 00:15 ( ruclips.net/video/U3mpklj7_Yo/видео.html ). This rapid power up causes the boat to transfer all pressure to the port wing. When this happens the boat again is experiencing a big puff so the power has to go somewhere. The person flying the foil would have max down trim on but their is still too much power in the boat to prevent it climbing on the foil. Watch the boat then tip back, start to heavily drag the port stern, and that sudden drag increase allowed the back of the boat to become a fulcrum, the boat rises up (40ft?(i thought it heard that quoted) & the fun is officially starting. When the boat comes back down its going 50 mph and falling off a 40 foot cliff. The interior structures in the boat acting like ribs and braces- did not yield. The boat falls back 40 feet to the water , lands on the port forward quarter and all that energy had to go somewhere. Water is incompressible & gives zero F's. The boats "bones" so to speak were not giving way , so it left the path of least resistance. If it had landed square on the "keel" line American Magic have stated the boat would have been fine. That was a car crash. The stringers inside the boat acted like a guillotine. the carbon fiber skin found itself between two immovable objects and the combined weight of the boat and the enrgy from the fall caused the boat to go straight through the skin of the boat. Kinetic energy is like a honey badger, it don't care who you are, it always wins. -------------------------How sailboats work explained -------------------------------- (incase you are not a sailor, the way sailboats sail upwind( these boats are going so fast they are basically upwind on all beats due to the forward angle of the apparent wind) is that the sail acts like a wing trying to generate lift. Take this example: {the boat is on starboard tack{ wind coming over the right side & the sails on the left side of the boat} sailing to weather. The sail plan is creating lift like i said and this would be trying to push your craft 90 degrees to the bow ( blow your butt sideways). This is Why sailboats have [keels/daggerboards/ canting freaking foiling wings ;) ] These structures underneath the boat prevent the sideslip. This forces the boat to heal over and go forward. The rudder and keel ( or in this case rudder and wing) are the primary points of contact for the distribution of that energy ( a traditional monohull also prevents sideslip from its wetted surface, further increasing the boats motion in heeling and accelerating forward. The second that puff hit it was good night Irene. These boats are doing 3 times the wind speed ( the fastest ive been was 17knts on a Thompson 30 ( boat designed to plane while sailing downwind. Fast F'er) ------------- This is just a summation but i hope it helps you understand what you are seeing. feel free to respond if you have more questions.
Great breakdown. The hull might be reinforced down the center for heavier impact, but not so much along the port side where it took the hit. I still believe the impact load on the foil as it reentered the water was the source. A distinct cracking sound can be heard immediately after the foil reenters(0:18) prior to the hull splashing down.
@@northernguy8860 the amount of energy from the foils drag without a doubt played a part. I personally think the shock load on the was making a point of pressure right about where the hole ends up. So the foils already dragging, and then the boat smacks back down... 1 2 punch. --- i just watched the video of AM's near pitchpole on their first day sailing Patriot. This time by being rolled over the bows buoyancy was not able to eat the impact. The sailing world is a tight nit one. That boat will be back out, but SOO much work in front of them, Electronics toast, foil cants ---toast
You are correct on the cause of the hole. But not the runner being the issue ask any ice or land sailor. They will turn at higher acceleration than this. Easing the main just makes it full of power you cannot dump it enough. Easing just makes it stupid full. Look at the initial bare away lots of white. Air is being sucked in, the down wind turn was just to hard. If they had taken a wider turn they would have extended their lead.
@@grahamm2015 Ex Americas cup skiper Ken Read had a great breakdown of the incident. he speaks to how having the main hard on the runners caused the boat to twist in the air and land off the centerline. ruclips.net/video/BNOVcOsNh9Y/видео.html It was an interesting watch. - also listen to your damn team-members when they voice concerns over the feasibility of success of a given maneuver. They started the bear away without building speed back up. As ken will talk about this shifts the apparent wind and sets them up for fun. Have a good afternoon.
Excellent explanation. Worth mentioning, it appears that at about 16 seconds in the rudder quickly goes from a moderate port direction to 90 degrees off the direction of travel. This significantly increased drag at the stern and probably contributed to the slamming effect on the boat when it re-entered the water.
The reason they could not dump the main, is that they are all sitting directly to leeward of the boom after the tack , and a dump would have taken their heads off. Literally .
Yes, at about 0:24, just above the semi-transparent image of the cup, appears to be the piece of the hull that produced the hole seen when the boat was lifted out of the water.
As far as I have read every think below the water is powered by battery and above the water in hydraulic, like the runner not being released as people have said here, So i guess it could have been a hydraulic fault or whatever, sounds like people are blaming the skipper for good to fast around the mark, they where only doing 30knots.......Whats Amazing is the Kiwis and every chipping in to repair the boat to get them racing again....
@@kermets Everything is hydraulically powered on the boat. The Foils and foil arms have hydraulic power provided by battery driven electric pumps. Above water grinders generate the hydraulic pressure which is stored in accumulators.
Here's a question. If you pause the video at 0:10 I think the port side spreader on the main is already bent backwards. Then at 0:26 you can see a marked difference in backwards angle. Is this because something had already broken before the stall?
Good pickup George - if you click on SETTINGS on yr screen and adjust PLAYBACK SPEED you can slow the video down to observe things ... not sure if that helps... ;)
The 'Magic' is the way we whipped a 'U turn' on a dime around the left marker (instead of just taking the easy way around the right marker), pulled up the right foil, took a brief skyward flight, smashed back down busting a hole in the hull, then capsizing.
No 'Magic' here. "American Tragic" is more like it, with madman DB at the wheel. I think he has ensured that he'll never be allowed to drive another AC boat after this effort, which will likely be over sooner than later, and with just cause. Bear away(right turn) was the call here. That completely unnecessary left turn could've killed several people. TH deserves sacking, too. Most expensive grinder on the circuit, is Terry. Shame he isn't actually calling tactics here, which is what he is supposed to be doing......
I don't understand why they awarded the race to Prada? Traditionally you have to finish the race in order to win, no matter what happens to your competition.
Why didn’t they bring the starboard wing down? Surely there is a point when the boat has rolled that the windward foil can move down to stop capsizing?
They would never have got it down in time and with that much wind force acting on the mainsail the foil would have done nothing, just get dragged out as the boat goes over.
@@mini696 At a certain point, the foil weight becomes a downward weight straight through the hull, so at some point the wing is the highest point of the boat, if you lower just before this the boat may stay upright, but to prove that or prove me, they would need to have a similar condition and try my technique. 😎
Who was responsible for the running backstays? Looks like it could have been saved but the main could not be released, the boom was caught on the port backstay.
With the camera view it seems the helicopter was right over the boat! YEP - at 7:28 copter is just above the boat so adding some wind and turbulence for sure.
There are two runners one for port and starboard they run from the top of the mast to the stern instead of a single back stay, only one is used on each tack. So I guess they should have released it to let the boom go passed or the boom got caught in the slack runner rope.
Running backstays are a common way to provide support for a mast, they are an alternative to "conventional" rigging. But someone has to literally take the slack off one side and tension the opposite side, much like the sheeting on a genoa, when you cross the wind. Good for racing boats with extra hands, busy stuff for shorthanded crew. And if someone forgets to throw one free...someone on that boat is not a happy camper. Usually it is just one more line, simple rigging, nothing that would mechanically fail by itself that way.
Agreed ..... Barker thought his was the right call which I respect, but for a boat in the lead and a gusty wind that was shifting, and rounding a marker ....... major crew error, which Hutchinson stayed well clear of in the press conference.
Listen folks: I am United States Navy. US DD 680. I appreciate and applaud the commentators' courtesy in trying to find fault -- any fault -- with the weather to describe this unmitigated disaster.

Turned too fast....generated too much centrifical force, like a race car taking a turn too tight and flipping, and then too slow to pop the main sheet out of the cleat to let off wind pressure... so over they go......you can see wind gusts coming over the water, turn downwind or upwind to keep force off the main, or pop the sheet...
@@alan_davis You'll find some modern sources that do not differentiate but traditionally, a capsized boat refers to one that has completely overturned. I've never heard of a broach being called a capsize. On the other hand, I have walked on the mast while someone broached a boat. No one reffered to it by any other term. Maybe that's a regional thing, or a part of the push to simplify and popularize everything in the sport. Find any former USYRU member and they'll tell you the same thing. That's a broach.
@@lyfandeth literally been sailing all my life and never heard that term. Capsize has always to me me meant mast in the water, full 180 degrees upside down is called being turned turtle.
@@_Zekken I learned term in sailing books, possibly in Chapman's. And my USYRU and USCG trained and certified instructor definitely used the word on the day someone dumped us. Maybe it is an obsolete NE term. But if the keel isn't out of the water and you can still walk on the mast with dry feet...we called it broaching.
But what caused the hole in hull? Three mistakes in a row caused the capsize; the decision to go broadside to the squall, the ignoring of two mates warnings, and the non-release of leeward backstay.
The hole was likely the result of the foil leaving the water and reentering. Upon reentering, there was immediate extreme loading and the tensile strength of the hull was exceeded before load distribution could be more evenly spread out. Edit: It 's the difference between a steady, constant load, which materials are designed to withstand, and impact load, which is equivalent to a hammer strike. A point of weakness can be immediately overloaded with impact load.
The hole was caused by the hull hitting the water broadside on, from the high helicopter angle you can see the boat spins out when the rudder loses grip. Also looks like the leeward foil did flex on the impact too.
@@salmiakki5638 if you watch the press conference with Terry Hutchinson he says the hole was caused in manner I described. My remarks on the leeward foil is just my observation from the clips.
They were flying around the marker and it should have all worked out if only they could release the mains. Would have been beautiful if they could pull it off. Grip of these foils are just incredible.
This has happened before with the AC75s, but not with such damage. The language though, is being corrupted. Capsize means upside-down. Patriot was on her beam ends.
AC organisers must have at least a small team of divers in chase boats, right? I haven't heard or seen hide nor hair of any by the way. They must be there though, right guys? I talking to you AC organisers and don't give me any BS about STASS and knives. They have their place sure, but I'll take your heads off your shoulders in my reply if you go there. And no, I have no axe to grind and nothing whatever to do with the event.
its not a setup issue, the port running backstay was either not released or got jammed. The main is pinned against the backstay. ( with a dual running backstay boat you always release one while the opposite side carries the load of the mast. The main getting caught caused this because most of the power of that main is up high, without being able to roll the power out of the top of the sail they were in for a ride. These ac-75s do not have that much of a traveler so pressure management comes down to main trimming, instead of just dumping the traveler car to spill air out of the top of the main.
When sailing DN iceboats doing 80-100 km/h the fastest way to quickly reduce sail pressure is to fall off 5-10 degrees. Not sure if releasing the main sail in this situation had helped.
as a representative of donald trump i can assure all involved that his design would have been the greatest as it would come from the very best designer in the universe. i know this because he told me
American Magic will come back stronger from this incident. I believe they can make it for the 2 remaining round robins. They can win against Prada and then INEOS. And after that, no one would be able to stop them from winning the America’s Cup.🇺🇸🇺🇸🇺🇸
I don't really know, but that's a big hole in the side of the boat, and I imagine that wasn't the only damage. I would guess it's over for them this time around.
they are seaworthy, but they aren’t built for rough conditions. in the end, it was a combination of multiple things that caused the capsize. someone who understands sailing much more than me can explain that for you
Caitlin Holden I've been sailing for over 60 years. They are not seaworthy. Exactly like the very fast racing "skimming dishes" of the 1900s or so were unseaworthy. No seaworthy boat or ship would literally fly up out of the water like that out of all control. If the seas were really rough, sure, any boat or ship can capsize and founder. But the weather was not severe at all. I've sailed under full sail, including spinnakers, in that kind of weather with no problem whatever. Put it this way: would you sail in that boat in the Transpac? I don't think so.
@Norman Braslow they are not built for races like the transpac tho. They are built for short, quick races in mild conditions. It capsized because of multiple events. Im not a sailung expert, so I'm not exactly sure what is going on, but from my understanding it was a combination of that massive gust of wind at the wrong time, their high speed going round the mark and going for the wrong mark, and the backstay not being released. Again, it did not capsized because it was unseaworthy, all 4 of the boats have shown time and time again that they can sail. The teams would not pour that much money into boats that didn't sail well. Luna roads sailed in the exact same conditions as the patriot, yet came out perfectly fine. It was a combination of many factors at the wrong time that caused it to capsize
Caitlin Holden Actually, you have, perhaps inadvertently, put your finger on several aspects of seaworthiness. When things happen at sea, they happen very fast and even expert seamanship may not save the day. Generally, boats must be designed so that the seaman can take all precautions well before any foreseeable event occurs. If the unexpected happens, it must be designed so that the seaman has a reasonable possibility of corrective action. This is particularly so when the unexpected can kill or injure the crew. Here, it was very foreseeable that the boat could do what it did, and it was also known that the crew would be helpless to correct the mishap. These crews were incredibly well trained, and it they could not have prevented the situation, nobody could have. Sailing can be incredibly dangerous. I've almost died at sea from an entirely unexpected freak accident. We were several miles offshore in a 60 knot offshore gale. One cannot reasonably anticipate that a little 30 foot sailboat will explode because of a broken glass container of paint thinner, but she did. But, well before the boat blew up all of the crew had life jackets on, and sail had been shortened properly. And we practiced appropriate seamanship for the hour or so we were in the water before being picked up. Still we made mistakes, the thinner should never have been aboard, and we were out in a 60 knot offshore gale, with nobody else out there, but luckily our rescuers. We almost paid with our lives for that little mistake of leaving the glass container on board. We could have easily ridden out the gale, true, but that one little mistake with the thinner came within a hair of killing all of us. These boats are indeed just racing machines, and as such are very dangerous as we saw. I'm not saying that they should not be built or sailed, only that they are by definition unseaworthy and the crews need to know that they are assuming a significant risk of personal injury or death. And I'm absolutely sure they know that very well, and accept the risk. That's sporting activity. Life is full of risk, and risk confronted with training and intelligence can be a wonderful adventure.
there are some things that are simply unpreventable. it happens. but this could have been prevented, or at least done so that less damage occurred, they should have gone around the other mark, which was a much easier turn. also, unexpected accidents happen. this was one of them. this does not mean that these boats are unseaworthy. it simply means that mistakes were made, and this capsize is a result of those mistakes. whenever you do anything, there is always a chance that it capsule lead to injury or death. anything. these boats are only dangerous in certain conditions, like with strong winds. there happened to be a strong gust of wind at just the wrong moment, which also contributed to the capsize. it was not because they are unseaworthy

could it be that at 0:24 you can see a part of the broken hull in the water astern of Patriot?
Yes, at about 0:24, just above the semi-transparent image of the cup, appears to be the piece of the hull that produced the hole seen when the boat was lifted out of the water.
See my question regarding spreader angles before the squall and after
the green light ended to work just after the tack, you can see 4:40 - 4:45. This means they lost the power and were in black out, that's the matter!

what's the difference between a knock down and a capsizes apparently nothing ??????????????????????????????
Shark!
How did they right themselves after capsizing?
Either with a motorboat or by lowering the port foil, probably a motorboat
the support vessel pulled it upright by a rope
Commentator is full of it. Looks like a "running backstay" was not released Oops the commentator got it later in the video.
That’s what I see. Might have not got over had they been able to get the boom past the backstay
Turned too fast....generated too much centrifical force, like a race car taking a turn too tight and flipping, and then too slow to pop the main sheet out of the cleat to let off wind pressure... so over they go......you can see wind gusts coming over the water, turn downwind or upwind to keep force off the main, or pop the sheet...
Somebody should be heads up watching the weather. Not head down grinding and devising tactics too late. No excuses. Time to retire xxxxx
I want keels back.
More like American Tragic.
That's called broaching. You are not capsized unless the boat goes 180° fully inverted. Or at least, well past past 90°.
Incorrect. Capsized is defined as the mast being in the water.
@@alan_davis You'll find some modern sources that do not differentiate but traditionally, a capsized boat refers to one that has completely overturned. I've never heard of a broach being called a capsize. On the other hand, I have walked on the mast while someone broached a boat. No one reffered to it by any other term. Maybe that's a regional thing, or a part of the push to simplify and popularize everything in the sport. Find any former USYRU member and they'll tell you the same thing. That's a broach.
Turtling
@@lyfandeth literally been sailing all my life and never heard that term. Capsize has always to me me meant mast in the water, full 180 degrees upside down is called being turned turtle.
@@_Zekken I learned term in sailing books, possibly in Chapman's. And my USYRU and USCG trained and certified instructor definitely used the word on the day someone dumped us. Maybe it is an obsolete NE term. But if the keel isn't out of the water and you can still walk on the mast with dry feet...we called it broaching.
They call these the Formula ones of the seas, and as you know F1 cars crash to...lol
But what caused the hole in hull? Three mistakes in a row caused the capsize; the decision to go broadside to the squall, the ignoring of two mates warnings, and the non-release of leeward backstay.
The hole was likely the result of the foil leaving the water and reentering. Upon reentering, there was immediate extreme loading and the tensile strength of the hull was exceeded before load distribution could be more evenly spread out.
Edit: It 's the difference between a steady, constant load, which materials are designed to withstand, and impact load, which is equivalent to a hammer strike. A point of weakness can be immediately overloaded with impact load.
You're ignorance is showing...
The hole was caused by the hull hitting the water broadside on, from the high helicopter angle you can see the boat spins out when the rudder loses grip.
Also looks like the leeward foil did flex on the impact too.
@@salmiakki5638 if you watch the press conference with Terry Hutchinson he says the hole was caused in manner I described.
My remarks on the leeward foil is just my observation from the clips.
They were flying around the marker and it should have all worked out if only they could release the mains. Would have been beautiful if they could pull it off. Grip of these foils are just incredible.
Italy win.
duh
😮😮😮😮😮😮😮😮😮
This has happened before with the AC75s, but not with such damage. The language though, is being corrupted. Capsize means upside-down. Patriot was on her beam ends.
Turning turtle is upside down. capsize is mast in the water.
Boats are more and more just becoming planes. Just make a plane.
Slow down in turns!
If everyone pays more Global Warming Tax will this make the races better?
miss old boat :( 2005-2010
👍👌🇨🇦❤
Easier and safe doesn’t win the race. In heavy wind you follow pressure and worry about racing fast.
Still have to survive the race.
I doubt anyone would have done better under the same circumstances....
spithill handled it pretty well
He did but he then had time to hold back and gently Bentley. Dean Barker has dropped some real clangers and that was the loudest.
Other than not take such a risky maneuver when in the lead. It was a bad choice and it lost them the race and possibly the boat.
You know, other than all the other teams...
@@joestevenson5568
What's next, it's going to sink?
airbags and pumps kept it afloat.
it nearly did tho
Looks like the election.
Interesting that fascism came out of Italy and they passed Patriot and won.😑
@Seawolf well about that
New name for this boat the Biden/Harris express
this aged badly
Was really amazed me, that Luna Rossa just raced ahead, though they saw what happened🙁
What were they supposed to do????
The Americans had plenty of motorized helper boats out there. There was no need to invade Italy and bomb it in retribution.

AC organisers must have at least a small team of divers in chase boats, right? I haven't heard or seen hide nor hair of any by the way. They must be there though, right guys? I talking to you AC organisers and don't give me any BS about STASS and knives. They have their place sure, but I'll take your heads off your shoulders in my reply if you go there. And no, I have no axe to grind and nothing whatever to do with the event.
All teams have divers on chase boats.
@@alan_davis Cheers buddy.
Fools have the main sail boom permanently fixed into tight tacking position.
if only they had you along with them. the fools.
No thank you for your kind offer. But hopefully they will read my comment and add quick release to the boom.
its not a setup issue, the port running backstay was either not released or got jammed. The main is pinned against the backstay. ( with a dual running backstay boat you always release one while the opposite side carries the load of the mast.
The main getting caught caused this because most of the power of that main is up high, without being able to roll the power out of the top of the sail they were in for a ride. These ac-75s do not have that much of a traveler so pressure management comes down to main trimming, instead of just dumping the traveler car to spill air out of the top of the main.
When sailing DN iceboats doing 80-100 km/h the fastest way to quickly reduce sail pressure is to fall off 5-10 degrees. Not sure if releasing the main sail in this situation had helped.
Funny that kayaking makes you feel authorized to teach world class sailors how to deal with a 75 footer foiling at 80 km/h...
as a representative of donald trump i can assure all involved that his design would have been the greatest as it would come from the very best designer in the universe. i know this because he told me
Who?
?
Quitters.
do you mean they quit after the capsize?
@@Chikkitiger35 Yep.
dude, they had a massive hole in the side of their boat
they could not sail their boat
@@Chikkitiger35 That's no excuse for giving up.
They were over their heads in this league from the beginning, what an embarrassment.
American Magic will come back stronger from this incident. I believe they can make it for the 2 remaining round robins. They can win against Prada and then INEOS. And after that, no one would be able to stop them from winning the America’s Cup.🇺🇸🇺🇸🇺🇸
And then you woke up...
I don't really know, but that's a big hole in the side of the boat, and I imagine that wasn't the only damage. I would guess it's over for them this time around.
yea.. spoiler alert buddy, they lost EVERY SINGLE RACE in the round robins. dean barker completely failed
I don't understand english sorry I'm Italian... American Tragic what?? Say again please
These things are simply unseaworthy. End of story.
they are seaworthy, but they aren’t built for rough conditions. in the end, it was a combination of multiple things that caused the capsize. someone who understands sailing much more than me can explain that for you
Caitlin Holden I've been sailing for over 60 years. They are not seaworthy. Exactly like the very fast racing "skimming dishes" of the 1900s or so were unseaworthy. No seaworthy boat or ship would literally fly up out of the water like that out of all control. If the seas were really rough, sure, any boat or ship can capsize and founder. But the weather was not severe at all. I've sailed under full sail, including spinnakers, in that kind of weather with no problem whatever. Put it this way: would you sail in that boat in the Transpac? I don't think so.
@Norman Braslow they are not built for races like the transpac tho. They are built for short, quick races in mild conditions. It capsized because of multiple events. Im not a sailung expert, so I'm not exactly sure what is going on, but from my understanding it was a combination of that massive gust of wind at the wrong time, their high speed going round the mark and going for the wrong mark, and the backstay not being released. Again, it did not capsized because it was unseaworthy, all 4 of the boats have shown time and time again that they can sail. The teams would not pour that much money into boats that didn't sail well. Luna roads sailed in the exact same conditions as the patriot, yet came out perfectly fine. It was a combination of many factors at the wrong time that caused it to capsize
Caitlin Holden Actually, you have, perhaps inadvertently, put your finger on several aspects of seaworthiness. When things happen at sea, they happen very fast and even expert seamanship may not save the day. Generally, boats must be designed so that the seaman can take all precautions well before any foreseeable event occurs. If the unexpected happens, it must be designed so that the seaman has a reasonable possibility of corrective action. This is particularly so when the unexpected can kill or injure the crew. Here, it was very foreseeable that the boat could do what it did, and it was also known that the crew would be helpless to correct the mishap. These crews were incredibly well trained, and it they could not have prevented the situation, nobody could have.
Sailing can be incredibly dangerous. I've almost died at sea from an entirely unexpected freak accident. We were several miles offshore in a 60 knot offshore gale. One cannot reasonably anticipate that a little 30 foot sailboat will explode because of a broken glass container of paint thinner, but she did. But, well before the boat blew up all of the crew had life jackets on, and sail had been shortened properly. And we practiced appropriate seamanship for the hour or so we were in the water before being picked up. Still we made mistakes, the thinner should never have been aboard, and we were out in a 60 knot offshore gale, with nobody else out there, but luckily our rescuers. We almost paid with our lives for that little mistake of leaving the glass container on board. We could have easily ridden out the gale, true, but that one little mistake with the thinner came within a hair of killing all of us.
These boats are indeed just racing machines, and as such are very dangerous as we saw. I'm not saying that they should not be built or sailed, only that they are by definition unseaworthy and the crews need to know that they are assuming a significant risk of personal injury or death. And I'm absolutely sure they know that very well, and accept the risk. That's sporting activity. Life is full of risk, and risk confronted with training and intelligence can be a wonderful adventure.
there are some things that are simply unpreventable. it happens. but this could have been prevented, or at least done so that less damage occurred, they should have gone around the other mark, which was a much easier turn.
also, unexpected accidents happen. this was one of them. this does not mean that these boats are unseaworthy. it simply means that mistakes were made, and this capsize is a result of those mistakes.
whenever you do anything, there is always a chance that it capsule lead to injury or death. anything. these boats are only dangerous in certain conditions, like with strong winds. there happened to be a strong gust of wind at just the wrong moment, which also contributed to the capsize. it was not because they are unseaworthy
Dumm gelaufen
Who cares. What a waste of money
