It is my considered opinion that all containers should be made so that they
will sink if they go aglub.


They will unless full of low density water resistant cargo. The doors
on the boxes are not watertight. Electronics, with all that foam, just
won't sink. CRT's are bouyant. So is wood. Depends entirely on the
cargo. With the right cargo a boxboat is basically unsinkable.
Read the empty weight stenciled on one that I spotted on I-80.
Something over 8000 lbs. and they would weigh over 40 tons if full of
water. That is way too heavy for a boxboat, some of those carry 8 000
containers. Those ships will not carry 300 000 tons. that is
ridiculous, so the boxes have to weigh much less. They mostly start
out very bouyant, but they are not watertight, like I said .Even so
they can't be guaranteed to sink. They will take quite a while to,
however. even if they do, eventually. A container washed off a ship
and spilled a cargo of bathtub ducks. Scientists collected data on
currents for years. Had it not come open, it would not have sunk until
it dissolved into rust.
There are the floating oil drums as well.

Actually container ships are rated in 20 ft equivalent containers,


The figure I gave was for a twenty foot box. Seemed a lot, so I
refigured and got the same forty tons. I used ' The Calculator That
Takes No Prisoners,' the HP 48. The Chinese are building some 90 000
ton boxboats. To big for the Canal.
