Quantity = 3600 x Area of hole in sq ft x sq rt of depth.

3600 x 1/9 x 3.16

1264 gpm.

So another set of numbers we don't know what to do with now that we have them.

Greetings,
I'm unwilling to speculate but we know these facts for sure:
1) NO loss of life (the most important).
2) Water was entering the vessel faster than it was being emptied, IF in fact (speculation) it was being emptied at all.
3) I'm going to have to re-evaluate the pump system on our boat.

how does that compare to the chart I posted? (to lazy to do the reverse math right now )


but with a square root that results in 3.16 would be around 1 feet deep, the chart I posted would show that to be a little over a 4 inch hole...which9s not what I get when I reverse math it...more like a 2.25 inch hole.


My math could be off as I am whooped...

24.9% higher.

To me the variation of numbers makes sense as these are all just means of approximation. I would still like to know where the brackets belong on the Navy formula.

As to the formula used on your chart, you now do have me curious. Might have to reverse engineer that.

Here's what I get on your chart.

Q = 20 x sq of diameter (which is area if square) x sq rt of depth

So 4 inches at 10 feet would be

20 x 16 x 3.16227 = 1012

To sum up the water flow issue-if you have a 4" hole in your boat, lots of frickin' water is coming in your boat really, really fast!

I have to say I like the idea of the guy in the bunk as an early warning system! Just don't let him drink too much!

Maybe someone wanted the boat to sink. I know of an airplane in Hawaii that suffered an engine "problem" that put it in the ocean in a thousand feet of water, a ditching that was very convenient financially to the air cargo company that owned the plane.

Never say never......

Not likely with the owners on board. And 6 or 7 crew. To many to pay off, to many that could talk.

The best two days of your life: when you finally get to buy "The Boat", and when you sell "The Boat" or settle with the insurance company for the loss of "The Boat"

My favorite "was it an insurance job?"

Get a SAR call at daybreak....80 foot fishing vessel sinking 40 something miles off Atlantic City. It's March or April so the water temp is in the 50s if I recall.

We do our search as a Brooklyn USCG helo does their half of the search area for an hour plus.

We are low on fuel and declare bingo fuel to return to base to refuel. The brand new crewman says over the intercom...."sir, whats that off our port side?". Back in the day the Jersey coast was filled with trash and it looked like a line of trash way out. Even though this was the crewmans first rescue....he was pretty adamant (pretty gutsy considering the rank difference and the copilot was tapping the fuel gauge) that we investigate.

So I slide the helo over and sure enough, one guy laying prone in a survival suit, 4 guys in regular life jackets and street clothes clinging to him, and one guy with no life jacket in street clothes laying across the guy in the survival suit. Fortunately it was fairly calm (maybe 3-4s).

We hoisted 3 or 4 and the Brooklyn helo grabbed the rest.

We flew them to Atlantic City airport where ambulances staged and checked them out for injuries and hypothermia.

As the last one was taken off to the hospital in an ambulance with now a pretty big crowd forming, a reporter walks over to me and asks "do you think it was an insurance job?".... I turned to her and replied "if it was, it was some pretty poor planning on someone's part"...

Both helos were about to leave the area for at least an hour while refueling and restarting a search that probably would not have sighted them until well into the next search where it overlapped the first.

Several of the crew would not have lasted another couple hours in that water....they were VERY lucky...and no it wasn't the captain in the survival suit IIRC.

So whether or not this yacht was an insurance job, as Capt Bill pointed out, planning for contingencies is important in insurance fraud...

So does ABS. The rules for yachts follow the "standard" IACS wording that the stabilizer be fitted in a watertight compartment or if damaged cannot lead to flooding of auxiliaries or other necessary equipment or create progressive flooding.
Yup, as posted by RickB on Yacht Forums. Which leads to the question to what regs, codes and class was this vessel built?

It was built to ABS Class.

So that being the case, it could not have been the stabilizer area sinking the vessel. A strike would not have sunk the vessel. Unless of course incorrect maintenance, corrosion or faulty construction occurred.

It would seem the case. Now, their class was terminated in December. It may just be deciding not to renew as many do. However, it may mean that the normal survey that would have been done last year was not done.

Still, the stabilizer story, while possible, sure doesn't sound likely.

The article from PassageMaker / Soundings says

"Thirteen people were rescued from a 106-foot yacht that sank Monday evening in the waters off Fort Lauderdale.

A family of six from Brazil, who owned the yacht, and six crewmembers were rescued and were not injured."

What am I missing? 6 +6 = 12 not 13. Just a typo?

Maybe the guy who opened the scuttle valves jumped off in the inlet.

Or a friend of the family who the reporters didn't include in their "sound bite" style.

Captain.

They repeatedly list it as family of six, crew of six, and one captain. Don't ask me why they just don't call it family of six and crew of seven.
