Launch Capsize of Yacht Baaden

Launch Capsize of Yacht Baaden

Launch Capsize of Yacht Baaden

(OP)
I was just pretty sure this was posted here when the yacht capsized, but can't find any such post.

Anyway, the original video that came out a couple of years ago is here:
https://www.youtube.com/watch?v=N6TYQZd0HPs
Another video here: https://www.youtube.com/watch?v=lEBJjsdTyWY

And, the reason for posting now, is there is an NTSB report that makes for interesting reading:
http://www.ntsb.gov/investigations/AccidentReports...

RE: Launch Capsize of Yacht Baaden

But, if the launch had been in due center, would that tipping angle to port occurred in the first place? (Assumes the left support tires had not run off the concrete.)

RE: Launch Capsize of Yacht Baaden

(OP)
One thing that wasn't apparent to me is that you have to evaluate stability in the floating condition (which they did), but you also have to evaluate stability in the back-end-floating, front-end-up-high-on-a-dolly condition, which is not as apparent that it was done.

This is not my field of expertise. I just ran across the old video on Youtube last night, and wondered if that NTSB report was out, and it was.

RE: Launch Capsize of Yacht Baaden

I skimmed the report, but I seem to recall it mentioning that those conditions were not appropriately designed for in the launch sequence (could have had a lot to do with the differing load call values from actual versus submitted for the calcs).

This is very similar to the story of the 'Vasa', a 17th century warship that capsized and sank in the Stockholm harbor less than one mile into it's maiden voyage.

If any of you are ever in Sweden, you must stop and visit the 'Vasa Museum', it's absolutely amazing.

RE: Launch Capsize of Yacht Baaden

I thought the 'we need the rich because they drop some cash and take taxis when they come into port' apologism on the follow up video was precious.

RE: Launch Capsize of Yacht Baaden

Yeah, thank Gawd for 'em :)

An incident like this kinda brings a whole new meaning to the "hole in the water..." saying.

The problem with sloppy work is that the supply FAR EXCEEDS the demand

RE: Launch Capsize of Yacht Baaden

Yes, can you imagine the 'demographics' of the people who are regular viewers of that 'YachtVid' YouTube channel? Now there are some true believers in the 'trickle-down' theory of economics.

More proof of how important it is to choose your parents wisely :)

RE: Launch Capsize of Yacht Baaden

Back to the topic, 8,000 lb transcription error on a load cell reading contributed to ballasting error of a low margin vessel. I thought the transcription errors that I had occasion to point out were a lot.

RE: Launch Capsize of Yacht Baaden

It was all that dark beer in the port side cooler for the christening party.

Heavily hopped craft brew, no doubt.
