105' yacht sinks off Fort Lauderdale

13 rescued minutes before yacht sinks off Fort Lauderdale's coast - CBS News

I'm sure it's a little too soon (not enough information), but why would this happen? Sorry if it should be obvious. I'm a bit of a newbie. :-)

On vessels of this size it is really important to know how the boat is laid out and with what systems and how those systems are rigged.

Sometimes its active flooding where a system on the boat is pumping water in, and once it becomes enough, another opening or system backfloods and the process accelerates as more places that can flood do. I have seen on smaller vessels where this often is self correcting because the system that starts the flooding gets terminated (engine, electric pump, etc) before the rising water becomes critical.

Sometimes its passive flooding where water starts coming in through a failure ( say popped hose) and the same progressive flooding overwhelms the pumps.

One can discuss why roving checks don't see these failures early on or why the crew doesn't feel the boat's motion change...but it happens more than you would think.

Then there is just the outright catastophic failure that is unwinnable.... something like a wet exhaust system exhaust flange fails so the engine is pumping water in and water is coming in through the hole. Easily this can overwhelm pumps, exhaust makes the engine room difficult to work in till it clears.

Everytime someone comes up with all the solutions to these problems...somehow some vessel and crew manage to get into this situation.

But you are absolutely correct in speculating ON THIS INCIDENT....MUCH more info is needed.

I think they broke Rule #1. Water should stay outside the boat at all times

Are you saying you think this is the yacht in question? This shows it's only 42.5'. ??? Maybe it's another yacht with the same name?

Sorry guys, These things are often in meters, so I thought it was longer ... my mistake.

Looks like that's the one, at least from the last reported location.

Must have hit something. Water alarms would alert to broken hose etc.

looks like they just made it to deep water (900+ feet) at 11.7 nautical miles out.

Looks like bad luck. 13 miles out, 13 passengers, just bad luck.

The boat sank in 1200 feet of water in the Gulfstream with strong currents so it is not likely that the insurance company will even do an inspection.
With 13 people on board and at night there was a good chance the owner was on board, the life raft was deployed and there were rescue boats on the scene. I saw on local television it took two hours to go down. No injuries reported.

The alarms were probably going but if it were hose failure IMO they would have alerted the crew early enough to do something. IMO it sounds like a large hole not just an even large cooling or exhaust hose.

Again all just speculation.


I never said it was a hose and I guess wrongly assumed a newbie wouldn't know that hitting something and causing a large hole would make a boat sink fast...even though that's not guaranteed.


Your idea, while valid...is just that...random speculation at this point.


here is equal speculation....night, lots of untrained passengers on board, unknown flooding.....


captain decides best to get alarm out, get the passengers off safely in the dark...by the time he finally searches the bilges and they have enough water in them that he can't find the source says to himself "not enough pay in this job for this" and joins the others.


Just speculation...but that's all we have at this point because all we know is the boat sank and even a salvage crew didn't pass on anything obvious to the media.

This is a forum where crew and owners of this caliber yacht hangs out. If there's scoop you'll find it here. A few posts down there is a link to some dramatic IR footage from a CG helo......
