După mai bine de un an, NTSB a lansat raportul său despre răsturnarea și scufundarea iahtului cu motor Northern Marine Long Range de 90 de picioare. Iată un link către pagina în care publică rapoartele. Uitați-vă în partea stângă pentru „Launch Capsizing of the Yacht Baaden”. O eroare transcrisă într-o măsurătoare de greutate este motivul final al acestui accident. http://www.ntsb.gov/investigations/AccidentReports/Pages/MAB1514.aspx

Apparently, as per the NTSB, there was an error in the final weight calculation and center of gravity estimation of the yacht so they put too much ballast weight which in turn resulted in low/poor stability.
Ultimately, what gets things done is not rich folks letting go of some of their cash. The economy is always based on the not so rich actually doing work.
What was the reason it sank.? Was it a design flaw it looks top heavy .
What a useless follow up! Nothing about the cause of hte problem!
Interesting reading. Summary. Never would have thought a motor boat would be ballasted like a sailboat but the boat should have had 23 tons of lead ballast. It only had 16 tons. 2 of those tons of ballast were not secure. The boat had an 8,000 lb weight imbalance that was missed. Final nail was the narrow ramp where one sides dollies slipped off the side starting the whole roll process.
why are there even people on the boat during the launch.. that seems pretty risky for the exact same reason what eventually happened…
This fellow is preaching to the choir. Apparently some one does not know the economic impact of this yacht at it's travel stops.
The accident report was published in August http://static-yachtsmagazine.s3.amazonaws.com/wp-content/uploads/2015/08/MAB1514.pdf
Seems someone wrote a "0" instead of and "8" on a form that was to be sent to the naval architects doing the stability calculations. Consequently, one side of the boat was 8,000 pounds heavier than it should have been. Also, for some reason New World/Northern Marine indicated a ballast mass of 23LT, but only installed 16.16LT. You can see what happened next.
what is this? A stolen clip to comment on for self glory?
One town should not rely on a boat with a handful of people coming through buying groceries to support them. I think the boating industry is definitely a large economic fundraiser for any coastal town, but focusing more on the "poor" folks who don't get to see this boat come to town is quite bullshit. The manufacturer launched this boat INCORRECTLY, in my eyes it was a risk to the customer, a risk to his employees and the safety of everyone in the area not to mention the surrounding boats. I think we should load the manufacturer up with so many fines they have to go out of business. Trust me the yachting world will survive. After all, this is a planet mostly made of water
The ironic fact is, this event CREATES more jobs, the opportunities you speak of are only Delayed, for the present, there were the barge people,the rescue services,the media,the insurance assessors& the investigators etc etc.This incident is an accidental blessing for many ,many people. Bravo the sinking 🙂
Curious, why was the boat not stopped and allowed to take on ballast and then slowly lowered further into the water? Seems that would have provided the much needed stability that could have avoided this costly event.
If I were to ever get rich, I would rent these things [yachts] for short term cruse. then be on my way and let some one else throw $$ into that hole in the water.
good thing it never go to deep water… twits who did the weigh in…
As a former marine Engineer I would have had a near heart attack when she heeled over. The engineer is always in the lower spaces to observe any leakage but to have the vessel unbalanced that's both the yard and Engineers responsibility. Lots of lost time there, glad no one was seriously hurt.
Well, if they don't know how to properly and safely launch a boat then they deserve not to work in the industry…
In the end,isn't it just another piece of junk?? More shit for marine life to endure..when I say marine life,I don't mean boats,.
Question is why did it sink.. any links thx
The story gos they got rid of the one guy that knew how to launch a boat like that. Trying to save a buck and it bit them in the ass big time
Here's some highlights of the investigation.
The vessel was weighed in July 2013 and found to be within limits.
The vessel was weighed again in March 2014 and found to be within coast guard limits.
The investigators reviewed the photos of the second weighing, and found the company doing the weighing used a grease pencil to write down the numbers from the load cell, (device used to weigh the ship). One load cell read 60, 350lbs while another read 60,550. The ship had ballast installed and this would require movement of the ballast to balance out those numbers.
The load cell that read 60,350 lbs was erroneously recorded and given to the naval architect as 68,500 lbs. A completely wrong figure. The naval architect had the ship wrongly balanced by more than 8,150 lbs. to port side. The fault is with the company hired to weigh the ship, which was called New World.
Post analysis review of the balance calculation revealed the ship would heel over no matter what.
The launching method of using two doilies was not reviewed by the coast guard, but obviously to anybody who watched the video, the doilies were overloaded because the tires were flattened trying to carry the weight. The front dolly could not (and was not designed to) support the off balance rear of the ship as it entered the water.
Also not mentioned in the report is of a crane launching using a cradle would have gone better. This method more than likely could have saved the ship as the cradle straps would have prevented the list from getting too severe.
