1. Was Rick Scot on-board? (n/t)

[Polly Hennessey]

4. My first thought also. Hope springs eternal.

[Trailrider1951]

6. Yes, that was my question

Crossing my fingers.

[SheilaAnn]

21. My question too, first thing I thought of. n/t

[Zambero]

11. Tragically, most likely no

If this is indeed the case, Rick Scott will continue his campaign to sink Medicare and Social Security.

[Coventina]

24. That's what I was hoping! n/t

[Gruenemann]

2. Insurance policy near the stern exploded,

breaching the hull.

[NBachers]

7. I'm leaning toward insurance. I hope they'll be able to inspect it where it sunk.

[Mystery sage]

3. There goes half a trillion dollars down the drain literally

[JHB]

19. No, not literally. There's no yacht that cost 500 billion.

The navy could buy a few dozen aircraft carriers for that much.

[DenaliDemocrat]

5. They ate that last meatball...

😀

8. Because it became heavier than the water it displaces

Fairly common occurrence. These are all recent:

12. All insurance jobs, I take it.

Seems the yacht building industry would know about such a basic fact in ship building.

I mean aircraft carriers haul multiple aircraft, launchers, crew and all their gear, food, water and all kinds of stuff all over the world's oceans and don't effin sink from being heavier than the water they displace.

Sounds like there's a racket going on.

[Effete Snob]

14. Why assume that?

Waterborne vessels have sunk ever since people stopped floating on fallen logs. Big ships also sink all of the time for lots of reasons. So do medium sized ships, boats and ferries.

I said "became" heavier than the water it displaces. These things are not exactly built to mil-spec.

I don't think insurance investigators or insurance companies are uniformly stupid. I imagine they are pretty good at what they do.

Many of these things are owned by persons so wealthy that they probably self-insure anyway, instead of paying premiums to insurance companies that are being used as ATM's by their cohort, in your imagination.

16. Seriously. You're saying it is not unusual for...

ships to sink because they're heavier than the water they displace? I don't care what you say, that premise sounds doubtful, and
wouldn't professional, experienced ship captains, of all people, in charge of multi-million and even billion dollar vessels, be knowledgeable enough to not let that happen?

Making sure their ships and cargo don't sink and get to where they're going is what they're paid for.

IMO these "accidents" happen, but the vessels being heavier than the water they displace is probably the last reason they happen.

[Effete Snob]

20. If a ship is not heavier than the water it displaces, it floats

That is the only reason why anything sinks.


"but the vessels being heavier than the water they displace is probably the last reason they happen."

No. When a vessel becomes heavier than the water it displaces is the ONLY reason it sinks. You seem to be hung up on how it became that way.

Nothing will sink if it is lighter than the water it displaces.

This is the most basic principle of buoyancy:

https://en.wikipedia.org/wiki/Archimedes%27_principle

In On Floating Bodies, Archimedes suggested that (c. 246 BC):

Any object, totally or partially immersed in a fluid or liquid, is buoyed up by a force equal to the weight of the fluid displaced by the object.

Archimedes' principle allows the buoyancy of any floating object partially or fully immersed in a fluid to be calculated. The downward force on the object is simply its weight. The upward, or buoyant, force on the object is that stated by Archimedes' principle, above. Thus, the net force on the object is the difference between the magnitudes of the buoyant force and its weight. If this net force is positive, the object rises; if negative, the object sinks; and if zero, the object is neutrally buoyant—that is, it remains in place without either rising or sinking. In simple words, Archimedes' principle states that, when a body is partially or completely immersed in a fluid, it experiences an apparent loss in weight that is equal to the weight of the fluid displaced by the immersed part of the body(s).

And, I assure you, a fully-laden aircraft carrier is lighter than the volume of water it displaces. Ships have big empty spaces inside, and water is kind of heavy.

That's why it is important not to allow the water outside of the hull to come unimpeded into the hull. Because then the water starts taking up some of that space and the vessel proceeds to become heavier than the water it displaces.

I am utterly certain that is why things sink.

22. "Accidents" happen. Ships sink. Ships being heavier than the volume...

or water they displace is a very rare "accident" in my opinion. Experienced, professional ships' captains know better than to let this happen. Let's not be naive, it's more likely someone wanted the ship to sink than in the more unlikely event that an experienced ship's captain allowed it to be heavier than the water it displaced. An inexperienced captain, ok, maybe. But one normally doesn't get to be in command of a ship without the prerequisite credentials.

[Effete Snob]

26. There's a reason why...

Every ship, boat, and what have you, is required to be equipped with life boats, rafts, personal flotation devices, flares, a radio, etc.. these things are required for a reason.

As to your grasp of the essentials of “why do things float or sink”….

[brush]

27. Naivete.

9. If I was to hazard a guess, the rear barn doors were breeched by wicked following seas

[Liberal In Texas]

23. According to a post at the video link:

My friend (who is a mediterranean based yacht captain) told me this: 127 Foot Motor Yacht "Motia Saga" sank off the coast of Italy 9 nautical miles from the Catazaro Marina. The crew reported that a seal on the stern door (under water line) failed and started taking on water the previous night during the early morning hours. Boat leaned heavily on starboard and never recovered. The local Marine Authority attempted to tow the boat back to Crottone but never made it. 9 people were evacuated and are all safe.

These yachts look wonderful, but I wonder how well they're structurally designed and built for safety.

[Initech]

10. Uh... have you seen The Wolf Of Wall Street?

[brush]

13. Yeah, a racket, insurance job? Good movie.

DiCaprio is good in those roles. I liked him in the fake pilot movie too.

[MarineCombatEngineer]

25. Catch Me if You Can, with Tom Hanks as the FBI agent pursuing him.

It was based on the true life story of Frank Abagnale.

https://en.wikipedia.org/wiki/Frank_Abagnale

Damn good movie.

[Deep State Witch]

15. Which Russian Oligarch

Was the owner?

[harumph]

17. It was listing severely and still under power.

It (looks) to me like it was scuttled.

[brush]

18. Scuttled means purposely sunk, right?

Accidentally on purpose even?
