In any case, there you go, now you have seen one.

Seems to me trees are the biggest actual floating danger, the metal detector
isn't going to work for those, but as I said, it is a brilliant idea,
anything to appease the fear will work.
Actually plenty of steel containers will float, if only temporarily. All depends on what's inside. Rubber toys, tennis shoes, wood furniture, mattresses, fumed silica, any cargo in sealed boxes are a few that come to mind.

Re: Forward Looking Sonar

So, just buy a boat that is certified for ice?

Auto inflate pfd's.... life rafts....

BOY... you never would run into one of these would you!?!?!?.....

"Yea... It was the craziest thing... You're not going to believe this... but after the container holed the boat, the door popped open, and we were surrounded by 200 inflated life rafts..."

I'm pretty sure that is exactly what was in the container the Robert Redford hit in All is Lost.

Surrounded by 200 life rafts?? I don't know, it sure looked like 200 lifelike vinyl "companions" from here. ;-)

There's also been serious talk, especially in racing circles, about mandating a forward watertight bulkhead on the boat, typically where the bulkhead for your forepeak already is.

But unless you want to kidnap a sharp-eyed teenager and lash them where the figurehead normally goes...there's nothing that competes with a Mark I Eyeball for that job yet.
Corbin 39 has a very strong watertight compartment forward for such a reason as this. Of course, anyone who knows anything about the construction of Corbins will know that rupturing the hull is very unlikely in any event due to it's laminating schedule.

Re: Forward Looking Sonar

Good friend has admiralty law practice here in NYC.
He tells there are 1000s of containers floating around,perhaps 10s of 1000s.
He gets alot of cases of container collisions and also for "lost cargo".

As for aluminum containers- I doubt they exist !
I've had half dozen "refers" for my farm biz.Steel frame with steel sheet exterior,SS sheet wall/ceiling with heavy aluminum extruded track floor fastened to STEEL.

They'll show up on magnetometer or ferrometer.
focsle watertight bulkheads are suggested ! Lol


All the Best

Honest sweetie... I was just trying to stay afloat, and the thing kept trying to squirm out from under me...
