What about boats which go underwater |
Was on the ferry in rough weather , so thought to myself , Why not have a boat which can
drape a waterproof double layer canopy around itself in rought weather and go underwater where there
is no risk of capsizing?

They are called submarines.
The "waterproof double layer canopy" is generally made of steel so it
doesn't collapse as soon as the boat submerges.
There are also a few problems with ventilation and running engines under
water, but they were pretty much solved about 100 years ago.
You may have read something about submarines in one of the comic books you
read under the covers with your LED flashlight after mommy puts you to bed.

how about trains that go underwater instead.

This concept reminds me of something similiar I had in mind for an
engineering concept that could build a bridge theoretically any
distance, say between America and Europe. The cars however on the
bridge would be "bubble cars" perhaps on a mono-rail. If there is very
bad weather or if part of the bridge collapses, then the bubble cars
can float and survive partially submerged until the storm is over and
rescue arrives. Sort of the same idea of something above surface being
able to adapt in an emergency to survive in it's own bubble or "double
layer canopy". The bridge however is distinct because it exists through
pontoon style floats beneath and helium blimps above. Very flexible but
vulnerable to the piped helium supply being broken or the pontoon
floats being lost in rough weather. Hence bubble car passengers must be
able to sit tight for a few hours under their "waterproof canopies"
before rescue. Take your own sandwiches and you could "mono-rail" it
from Liverpool to New York in a day - and what a view beneath your
"double layer" perspex canopy!

As they used to say at the shipyard, "all submarines have deep diving
potential."

Here is the job.
Move 20 tons 1 mile by hand.
if you role on a cart 200 pounds a trip..you make 5 trips a day..its
hard to push.
If you put it all on a barge one hand will push the barge slower than
the cart and it takes all day but is very easy .
1000 pounds per day by rolling or 40,000 pounds per day easy.
the less drag on the barge the easyer it is.
6000 ton train neads 4 engines.
2500 hp each 10,000 hp.
30 ton fuel day 1250 rpm.
6000 ton ship 2000 hp 3 ton fuel day .longer stroke 230 rpm
ship at 12 knots train at 45 knots.
4 x 3 is 12 ton vrs 30 for the trip.

You are a greater idiot.
So everybody have just been imagining submarines. Or planes for that matter?
Or even cars and trucks?
Woe to those who have you as their uncle.

Hey stooopid, nobody proposes submarines as an efficient conveyance
for people or materiel. Supersonic transports are fools' tasks for
the same reason. The Concorde was a giant sucking fiscal sound.
Trains are much more efficient than trucks.
Hey idiot, do you know what conveyance in the Space Scuttle costs?
$30/gram. Now go have somebody competent look up today's price of
gold.

I meant some kind of invention which would make an inflatable
draping for a boat to convert it into a submarine so it could continue
underwater in rough weather.

The cover would behave like a shrink wrap for the items on deck
as soon as it was more than a few inches below the surface.
If you had a sub/boat/shallow submarine with watertight hull and very
reliable
bouancy control you might be good to 100 feet or so. Your cover might
be good for lazy people to avoid having to stow deck items.
To dodge really hairy storms you need to go down about 500 feet,
so you need a real submarine anyway.

That shrink wrap effect would also turn cars and trucks into
very small metal balls. 1200 feet is the limit for modern subs.
Avoiding a storm is pointless, once you are under water.
You will still have wave effects, that move you around.

How fucking stooopid can an idiot wog be? INFLATABLE so it goes
UNDERWATER. Let's load it with concrete so it flies.

a truck is 3 mpg per 20 ton load.
1000 miles per truck is 300 gallons $ 600 bucks , 50 trucks is 150000
gallons per 1000 tons in trucks.
A 1000 ton ship is 2 ton fuel day $ 300 bucks.
it will take 3 days $ 900 bucks .
$ 30 000 vrs $ 900 in fuel cost.
A train is worse than a truck.
$ 2.50 per road mile $2500 to get one truck 1000 miles.
A good dutch coaster 400 gt 1000 dwt
will take 50 and cost you 100 grand to buy and 30 grand dry dock and 1
new $ 50,000 diesel.
find all the bad steel and cut it out and weld new in and zink the hull
..
200 grand in a boat .
$ 3500 day tramp .
me ,,I started with a 1000 ton ship and ground wood for paper off the
beach for free and sold at 170 per ton. reloaded evry 10 days.
had a 1200 hp dutz in it.

The fuel bill would suck.
if a bulker under water is a sub or a tanker.
So much of a tanker is underwater and still tanker hulls are cheep trans
per ton.
But if the tanker was 1 mile long and 10 feet wide and 200 feet
tall with a draft of 100 feet you could do 1 container wide like a
giant wall
and use 10 % of the hp pushing it.
The side friction on 5000 feet is small .
100 foot draft in a boat 100 feet wide moves 10 times the water to go
forward 100 feet.
But thats a hard boat to biuld .
the fuel saved is still 90 % .
100 containers long 2 containors wide and stacked 16 high .
3200 containers.
never empty anyway .
3200 containers 5000 hp. 16 knots would be killer.
