It is my considered opinion that all containers should be made so that they

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.

If I'm not mistaken the maximum total weight of a 20 ft. container is
35,000 lbs., and a 40 ft. container 45,000 lbs. I believe that the
Emma Maersk is considered the largest container carrier in the world
with a capacity of at least 11,000 TUE's.. Length 396 M, Breadth 56 M,
Draft 30 M. No mention of displacement. 110,000 BHP, a cruising speed
of 27K and a crew of 13.

Maresk has the reputation of under stating the capacity of their ships
and outside estimates of capacity are in the range of 14,000 TEU's
giving a possible cargo capacity of 245,000 tons.

Gross weight for a 20' ISO 1C container is 52900 lbs, 24,000 Kg. For
a 40' 1A container gross weight is 67200 lbs, 30480 Kg. Typical tare
weights are about 5000 lbs, and 8000 lbs respectively, though there's
a lot of variation. I think Casady was talking about the mass of
water they'd hold, which determines whether they'll sink or not.

The 8000 pounds figure was empty weight, and the 40 ton figure was the
displacement, the weight, at 63 pounds/cubic foot, of a chunk of water
8x8x20 feet. At 35 000 lbs a 20 would float with half of it out of the
water.
The original question was if the could they be made to sink and I
pointed that if they started out that heavy , the all up weight comes
to a ridiculous total for the ships. As it is, a container of
machinery will slowly sink, but foam packing may keep a box,or enough
of them, the boxboat itself, afloat until it lots of rusting has
occured.

35,000 lbs., and a 40 ft. container 45,000 lbs.

Twice as big as a 20 would translate to 70 000 pounds for a 40, not
35k. 45 000 does sound reasonable for something light enough to be
legal on the roads, however.

Crew of 13? One watch officer, one on the wheel, and one lookout times
three shifts. Plus a cook, the skipper, and the chief engineer. Twelve
right there. The seven masted schooner Thomas Lawson, had steam
winches to work the sails, and a crew of 18, and I believe Lakers
mostly have a crew of 29.

Go to www.pancanal.com to watch ships go through the locks in the
Panama Canal. Mostly boxboats.

How about passing international law that all shipping containers must be
loaded, either with cargo, mixed cargo or cargo and ballast, so as to make
them negatively buoyant? Might complicate loading a bit, but would increase
safety at sea immensely.

Na, I never try to argue with Wilbur, er, Crap'n Kneel. I do, however,
retain the right to poke him with sticks from time to time.

Well, that would be hard to top, though I'm confident you'll

Hey, if he wants dumber, he can always read and study the posts of some of
the more......proficient? posters of this group.
One who has more, is worth more, and is better at everything comes
immediately to mind. Also, one from a bay-area in Kalifornicatia.
