Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

i'm guessing these pleasure super yachts are not hardcore sea fairing vessels that might not handle sudden extreme weather at all well. also might not be captained by people that would do all the right things in those weather conditions.
obviously i have no idea if any of that is true
In this case they suspect there were a number of features on the yacht that contributed to its sinking. It had the world’s tallest aluminum mast, a retractable keel and large openings for windows and hatches all over the main deck that were most likely unsecured at the time.
They suspect she was knocked down by high winds or a water spout. Sailboats get knocked down all the time but all the factors I listed above may have contributed to her being unable to right herself quickly and subsequently filling with water.
It really would have to be willful negligence from the designer, the engineer and the insurance company not to have the keel and mast balanced so that if it gets knocked down even to the point the mast touches the water it will self right as long as the boat does not take on water. It's the whole point of a keel on modern sailboats, retracting or not.
On a boat this valuable the insurance company would want underwritten engineer reports about the seaworthiness of the boat and will only insure you for pre agreed areas based on said report. It might not be insured but with a commercial crew that is highly unlikely.
If the keel was up for shallow draft or it fell off, this happened to a number of oyster yachts a while ago so its not that unusual, then they would be fucked. If it took on water in large quantities so that the bilge pumps could not cope, they would be fucked. However it should be unlikely that the windows are open during a storm with commercial crew onboard.
My guess is that the keel either part or all of it came off, that will fuck you even in calm seas.
From what I read it was also anchored, which according to my very own unscientific and probably incorrect hypothesis helped with the tipping over when the wind hit the tall mast because it couldn't even try to float with the wind.
Well there’s extreme weather and there’s extreme weather. There have been reports that the yacht was struck by a waterspout, which is basically a tornado but over the water. I’m not sure if the strength of it has been reported or not, but given tornadoes have been known to throw trucks and train cars it doesn’t surprise me that it was likely powerful enough to capsize the yacht.
Unlike trucks & trains, a sailboat is designed to roll side-to-side. One current theory I’ve read is that the waterspout damaged the mast, causing it to unbalance the yacht (and possibly damaging the hull). The combination of being unbalanced and being slammed by the waterspout likely rolled the hull enough to flood it within seconds. Even if the mast wasn’t damaged, a tornado striking the yacht broadside would have likely been catastrophic depending on the strength of the storm. And waterspouts that powerful are still rather rare so I wouldn’t blame the captain for not anticipating it.
There are now some reports as well that the yacht sank in roughly one minute. If that’s the case then it means the yacht indeed rolled very quickly and took on a huge volume of water in very little time, so much that it was unable to right itself or that its bilge pumps could contend with it. Again, not something that could have really been anticipated.
I've seen a clip about that. Many hulls are styrofoam with fiberglass. It's cheap, looks good, but doesn't do well with collisions and bad weather. If that's the case here is to be determined.
Go to any marina and 90% of the boats there are „styrofoam” and fiberglass. In this size range core fiberglass is a tested technology with many advantages over steel or aluminum hulls (those sink too when abused)
You see the Titanic was made out of steel and it didn’t handle collisions very well. Boats aren’t usually designed to hit things.
