I crewed as engr on a 90-something footer, about 30yrs old. The amount of plumbing below deck was phenominal. Some metallic, some hose, lots of fittings and valves. Some carrying seawater at sea pressure. None of that stuff was accessible so had to be original. If a leak formed down there, there would be no way to trace to the sea cocks and get it isolated before bilge was awash. Trash down there would clog pump strainers. Also, engines had 12" underwater exhaust with big gate valves that sure looked seized.
That boat scared the crap out of me.

Their comments had little to do with the technical aspects of a yacht sinking...even discussing grounding without knowledge of a previous grounding.

Which is why the engine room should have waterproof bulkheads with water tight doors. Unless there is someone in the ER that door should be closed and latched.
At least that's how it would be if I got to design it.......

You almost never see that on a boat unless it is built to class. And even then depending on to what state of class it's built it my not be 100% water tight.

If you read the ABS record in the link I posted, you could see that it has nine watertight bulkheads.

Gots to close the watertight doors, too. Before the water gets too deep.

Yes, even as a newbie, I had assumed they had not hit an iceberg...
Psneeld responded perfectly to my initial query.

Interesting timing. Class was suspended in September and withdrawn on December 28 for overdue surveys.

No BooBoo...I don't remember any boat named Yogi......
But I am sure your point is well made...plus there are hundreds if not thousands of boats just in my USCG/Sea Tow career that I studied that sank from progressive flooding.
Heck the Titanic had watertight bulkheads...someone just forgot to mention they would have been better carried all the way to the top. What good is anything half a**ed.....like watertight bulkheads that can't withstand pressures, the gaskets don't seal and all the bulkhead penetrations next to it are not sealed?
This is from an interview with the Yogi's captain....
" The yacht turned aft to the waves while they were busy with the engines. He told me the aft starboard side watertight beach club door blew open and a lot of water entered where he told Nedim that the portside watertight hatch blew open. (We are not sure which one he meant exactly.) "
Watertight doors "blew open"...then that yard was guilty as hell...that's not how they are supposed to work.

Funny-the first report I read this morning said the boat was being towed back to Lauderdale. Maybe they are into underwater towing?
I also remember Yogi. I have always wondered whether the owner even got to get on the boat before it sank.

Perhaps Sea Tow opened a new branch called Sub-Sea Tow?

Wonder if my boat insurance covers undersea towing.

My BoatUS insurance claims "no limits on towing," so I would assume it would cover that.

Most insurance on Classed vessels have a warranty that the vessel must remain in Class in order for the insurance to remain in effect. If Class was allowed to lapse, the owner might be in deep doo-do.
