We are working on a seastead design that will have a 40 by 16 foot living area above the water.
There will be 4 foot wide columns that are about 20 feet long going out from 
from the 4 corners of living area and down into the water at 45 degrees, which half of
each column under water.   The bottoms of the floats will make a rectangle about 44 feet wide and 68 long.
From the bottom of each column there will be 
2 cables going to the adjacent corners to hold it in place.
There will also be a cable making a rectangle between the bottoms of all the floats so we have some
redundancy in case one cable breaks.
The seastead is about 30,000 lbs I think but this is NOT a normal boat hull shape,
it is more like a tiny oil platform as far as drag.

We expect to use 2.5 meter diameter propellers on two submersible mixers and solar power to move
at around 1 MPH plus any help from using eddies.


We are thinking to have the metal work done in China and so want a design where the parts can be shipped.

We are keeping the floats under 4 feet diameter so we can pack 4 of them into a shipping container.

We also want the living area to be modular pieces that can pack into a shipping container.
The frame or beams around the sides will be such that they can fit.
I am thinking of a correlated plate for the body.  This way pieces can easily ship
and then we could bolt them together.  I am thinking either marine aluminum or
duplex stainless steel.   The legs/floats and cables will probably be duplex so there
is some simplicity to having the body also duplex so we don't get galvanic corrosion issues.
It is a tensegrity design and there will be a rubber layer between the legs and the body,
so we could probably get electrical isolation if we go with Marine aluminum.

How would you recommend we design the body so it can be shipped in a container?
