A lot of stell cargo containers have merchandise packed in boxes, protected by foam. They won’t sink.
Other containers hold many thousand sneakers, unsinkable rubber.
These containers may float for months or years, nearly level with the ocean, unseen in any kind of chop or waves.
This is one of the reasons I built a steel sailboat.
Was the welding tricky with that?
years ago sneakers were washing up on Ft Ftld beach forget the incident but it had something to do with containers ?
The Titanic was steel...just sayin...lol
Many years ago A 40-ton work boat I was on hit a shipping container near shore. It dented a few things on the bow and the boat had to be sent out for repairs. It felt like we had hit land. Captain says a good radar is needed to look for these things. We weren’t running a good radar. :) Those containers are invisible in the water.
Some time in the '90s, a container load(s) full of sneakers got washed overboard and broke open. For a few years after, marine scientists were tracking ocean currents via the sneakers.
We used to carry green hides from the Pacific Northwest to Asia. They dripped smelly salt brine all the way over. Until they figured out better packaging we had to replace steel decks after a few years of that.
What amazes me is if the storms are that brutal to such a giant ship, how does a 30 foot sailboat survive at all?
